Sperm's noun encyclopaedia of _ andrology
The sperm is man's ripe reproduction cells, form in the spermary.
The human ripe sperm is similar to tadpoles, it is about 60 microns long, is made up by the very beginning and end with movement function containing hereditary material of parental generation, , neck, middle, part of end four separately. I collect sperm's sport picture separately ' 69.1k) ,Very beautiful, worth visiting.
The odd-shaped sperm includes the shapes of the head, body, tail make a variation, or the mixing deformity of body of head. The head deformity is enormous head, head nuclear and the afterbirth thick liquid is reversed, mushroom one kind of heads, one pair of heads; The body department deformity has body in great and thick, Tenneco, triangles,etc.; The tail deformity has thick end, thick short and branching end and each; The mixing deformity of body of head has body of head that increases, the nuclear deformity lengthens and the body of head is mixed and lengthened etc..
Sperm's sports
Have several the intersection of sperm and sport of type, but a most common one have two, one to move forward directly, the sperm actually moves about forward; The second kind of sport is to swing, the sperm only swings the tail, but does not advance. Epididymis sperms and sport of the sperm of ejaculating types are different. Penetrate the sperm in seminal fluid different components, its sport type is different too. It is higher in penetrating a initial part of the seminal fluid because of the movement speed of the sperm, so penetrate a part of beginning rich in sperm of seminal fluid and is paid and fertilized dailily manually. , the sperm sport type is changing too. On condition that have oviducal mucus and ovum bubble liquid, sperm's sports accelerate. The prostate secretes liquid and seminal vesicle gland and secretes the optimum proportionate relationship between the liquid to bear on also sports to the vigor of the sperm. The seminal vesicle gland has compositions which damage function on sperm moving and vigor to secrete the liquid and contain several kinds; But the prostate secretes the liquid and stimulates sperm's sports. Mix kinin or kallikrein and seminal fluid sample, can improve the movement ability of the sperm. Take kallikrein for several months for sperm few patients continuously regularly, can increase the sperm number of the seminal fluid, and improve the vigor of the sperm. Kick the intersection of women and the intersection of reproduction and several hundred million sperm of line into, less than, can run, reach fertilize position by 100 sperm only any time.
It is sinusoidal wave that sperm's cilia spreads repeatedly with a kind of coordination order. In this way, regulate the sports of the sperm with the energy produced in the cilia. Shrink protein, thick fiber and little silk associating with it that the cilia has upper column of anatomy to arrange and managing a little. So in order to overcome the resistance such as a of liquid of such viscidity of neck mucus of the palace, have needed such motive force for a long time. Sperm's cells are in order to move forward effectively, must make the sport wave reach and coordinate, and maintain as a result in the development course.
Three-dimensional space model regarding sperm's tail moves, there is a lot of incompatibility, this may be because photos taken are basically all two-dimentional structure. But common understanding think, have one wavy to take exercises, pass from the base to the peak a main one at one level, this level is equivalent to wide one of sperm's head; It causes a kind of volution to move that one attached to this sport wave rotates the composition. But does not know it is clockwise direction or counter-clockwise direction that this one fastens and moves the composition.
When seeing from base to the peak, people sperm head and head agglutinate to rotate to counter-clockwise direction often, only contrary to fibrous small arm direction of silk periphery of the axle. If the axle silk is conducted in a certain way one shrink the pulse, then this is excited to pass silk of this axle along the same direction.
There are ATP playing an important role in the sperm in muscles shrink and three phosphoric acid adenosinase (ATP enzyme) ,They and sperm set up the connection while taking exercises in born, can react. Just as ATP offers a large amount of energy when the muscle fibre shrink, the resolving of ATP offers a large amount of necessary energy for the fact that the sperm fiber shrinks. ATP which the sperm consumed can be glycolytic through fructose can react and is supplemented with breathing to grow.
The supersession course produced energy (ATP is its final form) Spread to the structure that can change the chemical location into the mechanical kinetic energy. This kind of energy supply, supplemented partly by the substrate supersession of the medium, some are produced from the supersession route of normal position, including three phosphoric acid adenosinase. The start of flagellar sports, seem to pass second messenger and a phosphoric acid adenosine (cAMP) of ring partly With glucoside of a phosphoric acid bird of ring (cGMP) Rely on the endocrine to control. But react, compound body, come, start flagellar sport by the intersection of calcium ion and protein that activate mainly in a succession of.
The bio-electricity properties of the membrane of sperm quality, together with the regulating action of neurochemistry and transferase system of the special ion, namely the activation of Na +, K + depends on ATP enzyme of magnesium ion, may have causality with the coordinated function and movement speed of sperm's cells of the movement wave. The speed possibility of moving of the sperm is influenced by the fact that the flagellar movement frequency is changed.
The sperm happens, bes ripe and transports in people's embryo, can recognize primitive reproduction cells in development on the 24th day while making an appointment. They appear in the yolk Nang at this moment. Cell go on, have silk split, in 4- 5 travel round, go to, lie in the intersection of reproduction and primitive gonad of valley. The and later while swimming and going of primitive reproduction cell, increase rapidly through the cell division. By the 42nd day, can reach 1300 primitive reproduction cells, either turn into the original cells of ovum or turn into precise original cells to exist in the gonad not splitting up later. Letting pills faint and splitting up in early days, primitive reproduction cells are being distributed in the thin precise tube of song evenly. They keep resting infancy while being whole, but in youthful development in early days, precise former cell begin hyperplasia, by having silks to split and become the elementary precise master cell, did not begin meiosis until youthful puberty straight.
The men similar women in many aspects in adolescence, but there is obviously different some. It is measured with the height that the peak grows, men take place late for 2 years. Similar to the intersection of moon and by first menses accurate time point in order to indicate, reach sexual mature stage certainly, can make a variation greatly among each individual at the development stage of a certain age like women's development. Ketone of testis causes the physical maturity, second sex character for example sound that grows to enclose the sexual organ with men to be low-spirited, characteristic distribution of the hair.
Killing the cross section of testis of sufficient development, reveal the reproduction cells in thin precise tube of song are at different development stages. Cell these come from skin grow precise, wrap up by the intersection of song and thin precise basilar membrane of tube. Produce and secrete quality among Leydig of man sex hormone testis ketone cells and lie between thin precise tube of song. Another kind of peculiar cell namely sertoli cell, are close to reproduction cells in the thin precise tube of song. These cells are not a part of one of reproduction cell. They lie song to be detailed to in charge of basilar membrane and stretch people, in charge of while being precise, branch stretch different reproduction of stage into in the middle of the cell. Been thinking all the time sertoli cells only offer structural support in the testis for many years. Already knowing them now has a lot of important functions. In the adult, they are in charge of releasing and playing an important role to the song detailedly and smartly to the sperm. They offer one important protective screen, in charge of produce area of sperm, separate with other the intersection of song and thin precise tube, and they produced the androgenic conjugated proteln. Precise original cells and standing side by side with its neighbouring sertoli cell on the basilar membrane. It is like this in among quality interval and soak play a functional protective screen role among leather liquid in reproduction. Blood, blood plasma or lymphocytic composition of liquid in the thin precise tube of song and testis have different substances. Its potassium with less proteins and 3 times has no glucose. The density of amino acid also has a prominent difference; Glutaminic acid and Tianmen the quantity in the intersection of testis and liquid of amino acid is higher than the blood in winter. The most important thing is the basilar membrane prevents protein from entering the song to manage detailedly and smartly. This protects content thing, do not get along well the blood antibody that can react with the sperm work. It is spread through the basilar membrane that ketone of testis is very free. Have already found the density of the testis network liquid has been similar to intravenous blood of testis. Because it have hormone which doesn't take place more important and can transport effectively about sperm,and can last materials other at course blood circulation except.
The sperm happens taken 46 pieces of chromosome (liploid, 2N) Not that division precise to be original cell change into only lasting 23 chromosome ( monoploiding, N)Sperm a series of course. In the whole adult's life, the testis offers sperms invariably, transport and store in the enclosing genitals. Years old and 90 more than years old see normal the intersection of sperm and evidence that take place in 80 more than man. This kind of effective and continuous course is offered incredible reproduction ability.
In the thin precise tube of song, precise original cells are split through having silks, form the precise master cell finally. Youth initial grades of precise master cell go on meiosis form smaller secondary precise master cell, contain the intersection of monoploid and chromosome of number, secondary precise master cell split, become meticulous structure of afterbirth further. This not further reduction with the chromosome number of division. It is ten percent of the familiar course to turn from meticulous afterbirth into a sperm, there is no meiosis, do not also have silk to split. The last a series of development is called the sperm to take shape. Though has already finished the nuclear fission of cell at elementary precise master cell and secondary precise master cell stage, but the division of the afterbirth thick liquid has not been over. The composition of the meticulous afterbirth still links up through the thick liquid valley of afterbirth; Because its sperm's development was contacted by each other.
Count in the sperm of initial district of the epididymis relatively less, its density is absorbed with the liquid and increases by the skin on the epididymis. The young men of the health encloses highland tail and presents the little curly tube and is full of sperms in it. To allow sperm store and keep physiological the intersection of function and integrality enclose, faint the environment of the end zone understand seldom so far far. Like the rabbit in the animal, the sperm can keep fertility being as long as 30 days in the epididymis.
In maturity enclosed in the guilt, a series of change has taken place in the sperm. Enclosing already inactivity of sperm of letting the head faint and revealing that unusually moves about, is inclined to advancing in ring way. When they faint through enclosing, their swimming moves ability to turn into single directionality. The important change has taken place in the surface characteristic of the membrane of sperm quality, but not seen structurally and carried the body change behind people's sperm is ripe.
The penis can erect and organize making up by three pieces of long column shape. Flexible sheath surrounds around it. Each column -shaped body contains the rendezous space that blood vessel and sex can be full of blood flow while arousing. Two pieces of upper body in post form are called the corpora cavernosa penis, can make penis hard increasing length and width of penis corpora cavernosa penis parting the penis foot in root that penis do when erection mainly. The penis foot is formed adhering to to the human body, after they disperse in order to be strong in one kind of fibers, adhere to the pelvis bone on dissecting. The third body of urethral sponge of body in post form of the penis lies in the underpart of the penis. It stops in the glans penis. The urethra is passed through body of urethral sponge.
While erecting, the body of urethral sponge is soft than the corpora cavernosa penis. Lie in glans penis at the time of the orgasm oneself and increase to nearly twice as much as its volume at ordinary times. Feel nerve endings and have the strongest sexual desire to feel in a large amount for it. In the orgasm, the penis becomes hard, the urethra opens and expands, the testis part rises and lets a ball of skin and sheath membrane faint to increase. Excited to reach the intersection of platform and issue as sex, the intersection of seminal fluid and set in the intersection of prostate portion and urethra, one the intersection of ejaculation and inevitable feeling occasionally this. Lie in urethral the intersection of Cooper and gland of root ' Bulbourethral gland) Release its thing of content. Fasten before and the increase volume of testis, the scrotum is increased thick. In the sexual desire climax, the sphincter shrinks in the skin of wing, the seminal vesicle shrinks, the spermatic duct shrinks, erect sphincter shrink, the prostate shrinks, these shrink strength and force the seminal fluid to pass the urethra when penis shrink.
The coordination related to epididymis and spermatic duct, prostate and seminal vesicle wall smooth muscle of ejaculating shrinks. Increase thickly and particularly obviously on the skin storey carrying these conduit of walls far of epididymis and spermatic duct. The ones that stimulate and shrink the activity at the time of the sexual desire climax are final to come out under the control of Epinephrine Yes nerve fibre. On the contrary, erecting depends on one pair of sympathetic stimuli. Enclose far end zone and spermatic duct to let faint tail, take place obvious shrink under neural adrenergic fiber stimulate under belly only. Such nerve supply type prevents the generous ripe sperm during ejaculation through the spermatic duct and enters precise thick liquid and penetrates.
The ones that enclose sexual organ act on during ejaculation, the gland (bulbourethral gland) from seminal vesicle, prostate and Cooper of seminal fluid Accept the liquid. The seminal vesicle lies in the all of a sudden triangular back side of wing for the sex structure in pairs. They secrete the product rich in fructose and enter the urethra through the ejaculatory duct. The prostate centres on the urethral base bottom, make a gift of their things of content the urethra through a lot of small conduits during ejaculation. The prostate secretes a kind of clear liquid, a little acid and contain rich amount of acid phosphatasing. Arrest the intersection of rafter and the acid, zinc and some albumen, dissolve enzyme. The secretion of the gland of bulbourethral gland or Cooper imports the urethral ball. It was moist that they offered and lubricated the liquid to keep in the urethra. When and totally erect in the excitement climax of the sex, their content thing can be released before ejaculation, also there are a few sperms sometimes. Known testis androgen is responsible for maintaining the function of the accessory sex organ. The main function of seminal vesicle and prostate secretion is to transport sperms during ejaculation, but may play some function on the supersession of the sperm.
