6. Function Morphology covered with the tunica vaginalis,a serous tissue The outer layer of the testes,the tunica albuginea testis contains germcells(spermatogonia) and nursa cells (Sertolicells) Leydig (interstitial) cells are found in the parenchyma of the testes between the seminiferous tubules

7. Temperature Control Higher temperature causes degeneration of the cells lining the wall of the seminiferous tubules In cattle ambient temperaturesrange from 5o 21 o,the temperature inside the testes will be about 4 o below body temperature(38.6 o ) The role of the scrotum and spermatic cord in temperature control of the testes involved drawing Actual cooling of testes occurs by two mechanisms

8. Accessory Glands located along the pelvic portion of the urethra contribute to the fluid volume of semen assure optium motility and fertility of semen Vesicular Glands a pair of lobular glands appearance of a "cluster of grapes." Unique organic compounds Prostate Gland single gland located around and along the urethra, posterior to the excretory ducts of the vesicular glands small contribution to the fluid volume of semen Bulbourethral Glands located along the urethra near the point where it exits from the pelvis contribute very little to the fluid volume of semen prevent semen from flowing bak
