Where are testes located? | Scrotum |
What is scrotum made out of | Skin and CT |
What are testes surrounded by | Tinica vaginalis and tunica albuginea |
Tunica vaginalis | Outer serous membrane |
Where is tunica vaginalis derived from? | Peritoneum |
Tunica albuginea | Inner fibrous CT capsule |
When tunica albuginea entends inward, what does it divide into? | Lobules |
Which sex is tunica vaginalis found? | ONLY males |
what are seminiferous tubule | produce sperm (spermatogenesis) |
when seminiferous tubule unite, what do they form? | Rete testis |
what do the walls of seminiferous tubule contain? | germ cells and sertoli cells (sustenocytes) |
what do sertoli cells surround | developing gametes |
what do the tight junctions (contained by sertoli cells) form? | blood testis barrier |
function of blood testis barrier | protects sperm from immune system, toxins, drugs, etc. |
what is produced by sertoli cells for allowing transport in lumen? | testicular fluid |
what do seroli cells respond to? | FSH (follicle stimulating hormone) |
from where to where do sertoli cells extend | basement membrane to lumen |
what do lobules contain? | seminiferous tubule and leydig cells (instertitial cells) |
Where are leydig cells (instertitial cells) located | In CT between seminiferous tubules |
function of leydig cells (instertitial cells)? | secrete testosterone (hormone) |
overall location of the Ducts | from seminiforous tubule to rete testis, then into duct system |
what are the duct system composed of? | epididymis ; urethra vas (ductus) deferens ; ejaculatory duct |
how are ejaculatory duct formed? | union of vas deference and duct from seminal vesicle |
3 regions of urethra (prostatic) | prostatic; membranous; penile (spongy) |
where does prostatic go through? | prostate |
where does membranous go through? | urogenital diaphragm |
where does penile (spongy) go through? | corpus spongiosum of penis |
where does penile open to? | glans penis |
where does vas deferens enter to ? | pelvic cavity |
where does vas deference loop over? | posterior bladder |
what does spermatic cord contain? | vas deferens nerves, muscles, blood, lymph vessels |
where is epididymis located | posterior border of testis |
function of epididymis | stores sperm |
where in the duct system composition do sperms mature? | epididymis |
parts of th epenis | root; body (shaft), and glans penis |
what is glans penis? | englarged tip at the terminal end |
