this is the dense CT capsule around the testes | tunica albuginea |
this is a peritoneal remnant of the testes | tunica vaginalis |
the function of this structure is to produce sperm | seminiferous tubules |
what are the three cell types found in the seminiferous tubules | spermatogonia, sertoli cells, lydig cells |
these are support cells found on the outer portion of the seminiferous tubules and form the blood testes barrier | sertoli cells |
these cells are found in between the seminiferous tubules and produce testosterone | leydig cells |
name the cells of spermatogenesis | spermatogoonium (4n), primiary spermatocyte (4n), secondary spermatocyte (2n), spermatid(n) |
these cells absorb excess cytpolasm during spermatogenesis | sertoli cells |
these supporting cells form zonulae occludens (tight junctions) with each other near their base | sertoli cells |
what are some functions of sertoli cells | they are stimulatd by FSH to secrete Abp, which increases local testosterone concentration. they absorb xs cytoplasm from developing sperm, and secrete fluid to nourish cells. |
what is the epithelium found in the epididymis | pseudostratified columnar epithelium with stereocilia |
the sperm are stored and matured in this structure | epididymis |
this structure transports sperm to the prostatic urethra. the extensive smooth muscle here contributes to the propulsive force for ejaculation | ductus deferans |
name the three accessory reproductive glands of the make reproductive system. | bulbourethral gland, seminal vesical, prostate. the product of these glands are emptied into the urethra by smooth muscle contractions during ejaculation. |
what substances do seminal vesicles make to nourish sperm? | vitamin C, fructose, alakaline substance to neutralize acidity of vagina, and prostaglandins for sperm motility |
which zone of the prostate gland has the highest likelihood of developing cancer? | zone 1 (peripheral zone) |
these accessory glands empty their secretions into the membranous urethra | bulbourethral glands (cowpers glands) |
what is the function of the bulbourethral glands | produce alkali substance and mucous to lubricate urethra |
