Question 1

What is analogous to the inferior vesicle a in males?

Answer 1

vaginal a in females

Question 2

Can females have an inf vesicle a?

Answer 2

Yes. Males have a sup and inf vesicle aa. Females have a vaginal artery (analogous to inf vesicle in males) and if they also have an inf vesicle it will probably branch off of the vaginal a. The uterine a may also b off of the vaginal.

Question 3

Path of internal pudendal a?

Answer 3

arises from internal iliac a, leaves pelvis thru greater sciatic foramen below piriformis, accompanies pudendal n through the pudendal canal (Alcock’s canal) just med to ischial tuberosity

Question 4

Bb of internal pudendal a in female (6)

Answer 4

inf rectal, perineal, post labial, clitoral, deep and dorsal clitoral a

Question 5

Bb of internal pudendal a in male (5)

Answer 5

inf, perineal, post scrotal, deep and dorsal aa of penis

Question 6

Arteries associated with branching off inferior vesicle/vaginal?

Answer 6

males – deferential a
females – inf vesicle a (if present), uterine a

Question 7

What does the inferior vesicle/vaginal artery supply?

Answer 7

male – bladder, prostate, seminal vesicles, vas deferens, lower ureter
female – bladder, vagina, lower uterus, lower ureter

Question 8

Where do the gonadal aa (testicular/ovarian) come off the aorta?

Answer 8

just inf to the renal aa

Question 9

what is the difference between male & female anterior division of the internal iliac artery?

female: uterine artery & vaginal artery

Question 10

Answer 17

male: dorsal n. of penis

female: dorsal n. of clitoris

Question 17

what is the difference between the branches of pudendal nerve in females/males?

Answer 17

male: dorsal n. of penis

female: dorsal n. of clitoris

Question 18

what is the difference between the branches of internal pudendal artery in male/female?

Answer 18

female: posterior labial a.; clitoral a.; deep & dorsal a. of clitoris

male: posterior scrotal a; deep & dorsal a. of penis

Question 19

pathway of internal pudendal artery

Answer 19

arises from internal iliac a; leaves pelvis via greater sciatic foramen, below piriformis; with pudendal n. through lesser sciatic foramen
