1

What separates the pelvic cavity from the perineum?

Pelvic floor

2

What structures make up the pelvic floor?

Pelvic diaphragm

Perineal muscles

Perineal membrane

all in the urogenital triangle

3

What are the two muscle groups found in the pelvic floor?

Levator ani

Coccygeus

4

What is the gap between the levator ani muscles called?

What is contained within it?

Urogenital hiatus

Urethra (males and females) and vagina (in females)

5

What is the innermost levator ani muscle?

What does it enclose?

Puborectalis

Rectum

6

What are the three levator ani muscles?

Puborectalis

Pubococcygeus (to anococcygeal ligament, not a true sling)

Iliococcygeus

7

The levator ani muscles are (contracted / relaxed) by default.

contracted

8

Which somatic motor nerves supply the

a) superior

b) inferior

aspects of the levator ani muscles?

a) Nerve to levator ani S3-5

b) Pudendal nerve S2-4

9

Which lateral rotator of the hip is iliococcygeus closely related to?

Obturator internus

10

In what fascia does the neurovasculature of the pelvis descend?

Endopelvic fascia

11

What structures hold the pelvic organs in place?

Can you give an example?

Pelvic ligaments

Uterosacral ligaments

12

Which pouch is covered superiorly by the levator ani and inferiorly by the perineal membrane?

Deep perineal pouch

13

Which muscle, found in the male and female, is found in the deep urethral pouch and attaches to the external urethral sphincter?

Compressor urethrae

14

Which muscle is found posteriorly in the deep perineal pouch but is only named in males?

Deep transverse perineal muscle

15

Which glands are found within the deep transverse perineal muscle in males?

Bulbourethral glands / Cowper's glands

produce lubricant

16

Which deep gluteal muscle is the iliococcygeus muscle closely related to?

Obturator internus

17

What is the function of the bulbourethral glands?

What female gland are they homologous to?

Secrete lubricant and alkali amongst other things into the semen to improve chances of fertilisation

Bartholin's glands / Greater vestibular glands

18

Which veins are contained in the deep perineal pouch?

Dorsal veins of the penis / clitoris

19

What are the contents of the deep perineal pouch?

In both sexes:

urethra, external urethral sphincter, compressor urethrae, fat, dorsal veins

In males:

+ deep transverse perineal muscle and bulbourethral glands

In females:

+ vagina

20

Which lower limb muscles are closely related to the pelvic diaphragm muscles?

Obturator internus

Piriformis

remember these form the lateral walls of the pelvic cavity

21

In which space is the root of the penis found in males?

Superficial perineal pouch

22

The superficial perineal pouch contains the ___ of the penis in males.

root of the penis

23

What are the two parts of the root of the penis?

Bulb

Crura

24

Which structure develops from the bulb of the penis?

Corpus spongiosum

25

What is the purpose of the corpus spongiosum?

Transmits spongy urethra

26

Which structures develop from the two crura of the penis?

Corpus cavernosa

27

What does crura mean?

Leg

So the penis has two legs --> corpus cavernosum(s?)

28

What is the purpose of the corpus cavernosum?

Fill with blood during erection

29

What are the muscles associated with urination and ejaculation in males?

Bulbospongiosus x1

Ischiocavernosus x2

named for what they attach to

30

What are the three erector muscles found in the superficial perineal pouch in males?

Bulbospongiosus x1

Ischiocavernosus x2
