Q

what supplies blood to the scrotum?

A

branch of external pudendal artery/vein

17
Q

what are the layers of the testis?

A

skin
tunica dartos
spermatic fascia (external spermatic fascia, cremasteric fascia, internal spermatic fascia)
parietal peritoneum
visceral peritoneum

18
Q

what are the parts if the epidermis?

A

head, body, tail

19
Q

what is the function of the ductus deferens?

A

convey sperm from tail of epidermis to urethra

20
Q

what is contained in the spermatic cord?

A

ductus deferens
testicular vein/artery
(it is a peritoneal fold continuous with the vaginal tunic)

21
Q

what allows cooling of arterial blood before it reaches the testes?

A

pampiniform plexus (testicular vein wraps around the artery forming a mesh for heat exchange)

22
Q

what attaches the spermatic sac to the scrotum?

A

scrotal ligament

23
Q

what does the terminology “open” or “closed” castration relate to?

A

whether the abdominal cavity remains closed or is open (if you incise the vaginal tunic or not)

24
Q

what ligament is broken in open castration?

A

ligament of the tail of the epididymis

25
Q

what ligament is broken in closed castration?

A

scrotal ligament

26
Q

what are the erectile tissues of the penis called?

A

corpus cavernosum
corpus spongiosum

27
Q

what is the corpus spongiosum?

A

erectile tissue that encloses from urethra (bulb) to top of penis (glans)

28
Q

what are the two types of corpus cavernosum?

A

musculocavernous (smooth muscle with large cavernous space)
fibro-elastic (tissue arranged in a sigmoid flexure with small cavernous space)

29
Q

what supplies blood to the penis?

A

internal pudendal artery/vein

30
Q

what are the muscles of the penis?

A

retractor penis muscle
ischiocavernous muscle
bulbospongiosus muscle

31
Q

what is the function of the retractor penis muscle?

A

smooth muscle to help retract penis into the sheath

32
Q

what is the function of the ischiocavernosus muscle?

A

prevents venous drainage of blood during an erection
rhythmic contracts increase pressure in corpus cavernosum during erection

33
Q

what is the function of the bulbospongiosus muscle?

A

prevent venous drainage during erections
rhythmic contractions increase pressure in corpus cavernosum during erections

34
Q

what are the accessory glands that may be present in males?

A

ampulla of ductus deferens
vesicular gland
prostate gland
bulb-urethral gland
