Explain
the anatomy of the testis Testis
The first member of reproduction at the man, and no _khasatan when the man, located each on one side of the scrotum, and oval-like shape so that the eyeball, which is highly sensitive
Internal structure of the testis
Notes that the surface of the testis rear associated pole upper culvert, and extends from the inside testicular extensions fibrous complex up to albuginea, divided testicular to about 400 gap each containing tubes twist chair or more, along the tube about two feet two, positioned between albuginea and barriers fibroblasts under kind of pressure.
After a distance of 2 feet unite all tubes together to form a tube straight one, then Ttfagr these tubules among them the problem of network pipe Mtfagrh, known as network testis, and then unite all 6 to 12 tube of this network constitute channel tanker Efferent Duct, the number of channels formed between 15 - 20 channel interference to the beginning of the epididymis, and thus linked to all testicular lobules Balbrbouk by these tubes.
Microscopic anatomy of the testis Microscopic Anatomy
Seems fibrous tissue tunic white thick, and barriers and extensions fibrous divided testis into small pieces known as Alavsas Lobes and these in turn are divided into lobules Lobules, showing the seminiferous tubules twisted, each tube is composed of several layers of cells that are difficult to distinguish types accurately, as it appears inside lackeys Spermatids.
The cells appear testis supportive, and special cells known as cells Idg or ledge Lydig that secrete the hormone androgen known as testosterone Testosterone, and sperm cells that you configure sperm (sperm), the cells base called cells generating sperm Spermatogonia, divided into sperm cells initial Primary Spermatocytes, turn Meiosis Meiosis secondary to sperm cells contain half the number of chromosomes in the human. Then mature cells and turn sperm mature (sperm) and so that migrate nucleus to one end of the cell sperm secondary, which is the head, then narrowing and تستطيل cytoplasm (cytoplasm) to form a sin, and called then counterfoil Alntafah Spermatids, and when it enters into seminiferous tubules and remain there are objects separate called sperm Spermatozoa
And also show striking cases surrounding Bal_khasip the inside out:
- Albuginea Tunica Albuginea
Looks dense fibers when testicular pole and the mass of fibrous body called Hijmor Highmore him out extensions that divides the testis into lobules
- Class vaginalis VaginalisA membrane chapel located within fascia sperm, which covers aspects: the front and East side of the testicle, and consists of two sheets thin one internal cytoplasmic, and the second external mural hand lobe, and their gap-existent, which is infested by b Hydrocele Hydrocele where filled the gap bad fluid
- The fibrous layer of the deep:Consisting of transverse fascia and form a bag containing the spermatic cord and testicular, which starts from the internal crural slot, and connected at the lower pole of the testis scrotal Association
- The outstanding class CremasterIt consists of small oblique muscle
- The fibrous layer surface or peritonitisIt is a continuation of the large oblique muscle
- Layer Alselloseh under skin:It is a continuation of the tissue under the skin of the perineum
- Skinning (fibrous layer of the scrotum) DartosIts reddish color, is subject to constriction, a genuine leather muscle
- The skin of the scrotum:
Thin, rubber, colored, highly sensitive, and in the middle of long outcrop represents a docking place and scrotum papers which Tbkien separate when women constitute the labia majora
- Seminal vesicles:
Testis secrete semen to the outside via a pipeline and seminal channels are:
A - straight pipe:It microtubules in testicular Ovsas, which tubes or more per lobule
- Network testis Rete TestisA tangled pipes, consisted of straight pipe when union body Hijmor Highmore
C - epididymis EpididymisSteel tube located behind the testicle, is separated from the testicular furrow padded internal visceral class class vaginalis and named this groove pocket epididymis. They often twisted spiral shape, so that the in situ length of 5 cm, but real long since attracted up to six meters. And have three parts: a circular head and body triangle, and a thin tail.
D - the vas deferens Vas DefferensThin tube can touch finger from the top of the scrotum movement of sperm from the epididymis to the urethra, its thick muscular wall, Vicsabha rigidity, which is very narrow and very long, with a diameter of 2 mm and a length of up to 40 cm, can accommodate at the end made up ampoule.
Start from the guilt the epididymis and going through the scrotum فالقناة crural Valhod where it ends at the base of the prostate بإتحادها with seminal vesicle to be together channel bombers.
Begins her rise rear end upper testicle and then heading towards the canal crural within the spermatic cord Vtabrha diagonally down and forward and inside, and after passing the slot crural interior up to the area beneath omentum as the Bgrus or Bgros Bogros and here separated from the spermatic cord, which tracks walking on muscle Al_khasria Psoas , and pass is the area known as Rtseos between pelvic wall from the outside or the peritoneum The Secret - vescico of interior, and high omentum, and intersect with the umbilical artery on the side wall of the bladder. And up to peritonitis prostate - issued by the omentum diverticulum Douglas or Douglas Douglas, and pose with the vas deferens from the other side triangle with its base in the prostate is located between Ahoislten Alntin, where widening unite end (ampoule) with seminal vesicle Vtkon channel bombers
E - seminal vesicle Seminal VesiclesA reservoir of sperm, and two Hoisltan on each side ampoule vas deferens, shape elongated, and diameter غبر fixed, size 5 * 1.5 * 0.5 cm, and has three parts are the neck and the body and the bottom, and secrete semen, which is located between the following members:
1 - from the front surface of the rear bottom of the bladder, and the back straight
2 - ampoule inside the vas deferens, and abroad braids veins sperm
3 - from the bottom of the prostate, and the Supreme Douglas diverticulum
- Channel flush Ejaculator CanalUnion consists of ampulla of the vas deferens and seminal vesicle neck, two channels unsurpassed within the prostate, 2.5 cm in length, and pour semen bearing sperm in the prostatic urethra about prostate Alayibh Prostatic Utricle

Testicular functions:
The testicular two important functions:
1 - making sperm (sperm)
2 - secretion of testosterone
- The formation of sperm Spermatogenesis
Begins with the formation of sperm in all seminiferous tubules, during adulthood, and will last a lifetime.
And are formed with emotion of Exhorter hormone the pod FSH, and after manufacture are stored in the vas deferens to get the nutrients and get rid of carbon dioxide resulting from the metabolism.
And contain seminal vesicle on the amount of fructose and Alainoctol Inositol and amino acids and prostaglandin Prostaglandin and fibrinogen, and the vesicle empties all these contents moment ejaculation seminal at the end of sexual intercourse sexual within the channel flush or bomber, after the channel carrier (vas deferens) may emptied Ntaffha, which increases the size of the projectile semen, sperm and feed on fructose, then prostate secrete a milky fluid transparent base interaction, contains vitamin C, 12 and calcium, worked to reduce the viscosity of semen
