16
Q

function of ischioanal fossa

A

allows fossa to communicate posteriorly

*horseshoe shaped recess

17
Q

landmarks of the anal canal

A

anal columns, anal valves, pectinate line

18
Q

arterial supply superior to the pectinate line

A

inferior messenteric artery > superior rectal artery

internal iliac artery > middle rectal arteries

*this is dervied from hindgut (endoderm)

19
Q

arterial supply inferior to the pectinate line

A

*derived from ectoderm

internal pudendal artery > inferior rectal arteries

20
Q

venous system and sensitivity superior to pectinate line

A

superior rectal vein > internal mesenteric vein > portal system

*sensitive to stretch and ischemia but NOT pain temp touch

21
Q

venous system and sensitivity inferior to pectinate line

A

inferior rectal vein > internal pudendal vein > caval system

*somatic innervation- sensitive to pain temp touch

22
Q

lymph drainage above vs below pectinate line

A

above-lymph drains to internal iliac nodes
below-lymph drains to superficial inguinal nodes

23
Q

portal-caval anastomosis
-portal system aspect
-caval system aspect

A

portal system- superior rectal vein drains to inferior mesenteric vein
caval system- inferior rectal vein drains to internal pudendal vein

24
Q

function of portal-caval anastomosis

A

provides an alternative pathway in the event of a blockage

*if portal hypertension occurs can result in rectal varices aka HEMMORRHOIDS

25
Q

internal anal sphincter (type of muscle and innervation)

A

smooth muscle
symp- contract
parasymp- relax

26
Q

external anal sphincter (type of muscle and innervation)

A

skeletal muscle
somatic innervation-contract *inferior anal nerve from pudendal

27
Q

sexual function parasympathetic supply *function and nerve

A

-helps achieve erection
-pelvic splanchnic nerves

28
Q

sexual function sympathetic supply
*function and nerve

A

-helps achieve emission and contraction of internal urethral sphincter
-lumbar splanchnic nerves

29
Q

somatic innervation of external URETHRAL sphincter

A

contracts external urethral sphincter

30
Q

male and female galnds of UG triangle

A

*both secrete liquid for sexual function/ pre ejaculation

female- greater vestibular (bartholins) glands
male- bulbourethral (cowper’s) glands

31
Q

what is the pudendal artery a branch of?

A

internal iliac artery

32
Q

branches of internal pudendal artery

A

deep artery of penis or clitoris
dorsal artery of penis or clitoris
perineal arteries

inferior rectal artery *part of anal triangle not UG triangle

33
Q

venous system of external/erectile tissues

A

superficial dorsal vein
-drains skin and prepuce

deep dorsal vein
-drains glans
