female Repro week 5 test 2

Question 1

ovaries are held in place by what ligaments

Answer 1

1. Ovarian
2. suspensory
3. mesovarium

Question 2

Uterine wall three layers

Answer 2

1. perimetrium(visceral peritoneum)
2. myometrium
3. endometrium

Question 3

what are the two subdivisions of the broad ligament

Answer 3

1. vesicouterine pouch, between bladder and uterus

2. rectouterine pouch, between rectum and uterus

Question 4

vascular supply of the ovaries, uterus, and vagina

Answer 4

ovaries-ovarian arteries from the ascending aorta

uterine and vaginal arteries come from the internal ileac artery

Question 5

perineum borders

Answer 5

between the pubic symphysis and coccyx and then on the lateral sides are the ischial tuberosities

Question 6

what are the two triangles of the perineum?

Answer 6

anteriorly is the urogenital triangle

posteriorly is the anal triangle

Question 7

what are the superficial perineal muscles?

Answer 7

ischiocavernosus most lateral
bulbosongiosus next to genitalia
superficial trans perineal(separates the triangles)
external anal sphincter

Question 8

what are the deep perineal muscles?

Answer 8

deep trans perineal muscle
levator ani (all the muscle in the anal triangle other than the external anal sphincter)

Question 9

What are the external genitalia?

Answer 9

mons pubis
labia majora
labia minora
vestibule-recess between labia minora
clitoris

Question 10

what are the parts of the clitoris?

Answer 10

• erectile tissue hooded by prepuce
• crura of the clitoris erectile tissue
• glans clitoris is the exposed portion
• bulb of vestibule( arguable not part of the clitoris) extends posteriorly along just under the labia minora

Question 11

what do the greater vestibular glands do and where are they located?

Answer 11

they release mucus into the vestibule for lube
homologous to the bulbourethral gland in males
located just posterior to bulb of vestibule

Question 12

vaginal sensory innervation

Answer 12

upper 1/2 is visceral innervation

lower 1/2 is pudendal nerve(somatic)

Question 13

the Pudendal nerve

Answer 13

from ventral rami S2-S4
sensory- is perineum
motor- is perineal muscles

Question 14

Clitoris innervation

Answer 14

• somatic sensation is pudendal nerve (S2-S4), pressure, vibration, touch, temperature
• Parasympathetic: Pelvic splanchnic nerves (S2-S4) clitoral erection
• Orgasm: pudendal nerve (S2-S4) rhythmic contraction of perineal muscles
• *pudendal nerve is somatic, but ANS axons travel with it.**
