Flashcards in export_perineum ii Deck (17):
1

What is the deep fascia of the perineum fused with?

Suspensory ligament of penis or clitoris

2

Superficial perineal pouch - male

Potential space between membranous/Colles fascia and perineal membrane

3

Male superficial perineal pouch contents

Root of penis (bulb and crura)
Ischiocavernosus m.

Bulbospongiosus m.

Superficial transverse perineal m.

Spongy urethra

4

Deep perineal pouch - male

Space between superior fascia of UG diaphragm and perineal membrane

5

Male deep perineal pouch contents

Membranous urethra
External urethral sphincter

Bulbourethral gland

Deep transverse perineal m.

Dorsal n. of penis

Internal pudendal arterial branches

6

Vestibule of the labia contents

External meati of urethra
Vagina

Ducts of greater and lesser vestibular glands

7

Greater vestibular glands location

Open into vestibule, posterolateral to vaginal orifice

8

Greater vestibular glands function

Secrete lubricating mucus during sexual activity

9

Lesser vestibular glands location

Open into vestibule, lateral to urethral orifice

10

Lesser vestibular glands function

Correspond to male's prostate
Secrete mucus into vestibule

11

Female deep perineal pouch contents

Part of urethra
Part of vagina

Sphincter urethrae

Deep transverse perineal m.

Internal pudendal vessels

Dorsal n. of the clitoris

12

Nerves responsible for erection

Pelvic splanchnic n. (S2-S4)

13

Nerves responsible for emission

L1-L2

14

Effect of nervous stimulation for emission

Semen -> prostatic urethra
Peristalsis of ducts/vesicles

Prostatic contraction, and involvement of other glands to contribute to semen

15

Nerves responsible for ejaculation

Pudendal nerve (S2-S4)

16

Effect of nervous stimulation for ejaculation

Expulsion of seminal secretions
Affected by contractions of bulbospongiosus and ischiocavernosus m.

17

Autonomics involved with ejaculation

Sympathetics - close internal urethral sphincter
Parasympathetics - contract urethral m.
