1

How do the upper rectus sheath and the lower rectus sheath differ?

  • Upper sheath:
    • All 3 aponeuroses envelop each rectus muscle
  • Lower sheath
    • All 3 aponeuroses pass anterior to all the muscles 
    • The posterior sheath terminates abruptly at the arcuate line

 

2

The transversus abdominis contributes to the [layer of covering of the spermatic cord]

The transversus abdominis contributes to NONE of the layers covering the spermatic cord

3

The splanchnopleure gives rise to the [superficial/deep] body wall

The somatopleure gives rise to the [superficial/deep] body wall

The splanchnopleure gives rise to the deep ​body wall

The somatopleure gives rise to the superficial body wall

4

The [layer of the body wall] contributes to the internal spermatic fascia and deep inguinal ring

The Transversalis Fascia contributes to the internal spermatic fascia and deep inguinal ring

 

5

In females, the gubernaculum persists as which two structure?

Ovarian ligamnet

Round ligament of the uterus

6

What is contained in the superficial pouch?

(In general, not specific structures)

External genital organs

  • Penis
  • Clitoris (body and crura)

 

7

The [layer of the body wall] contributes to the cremaster muscle

The internal oblique muscle contributes to the cremaster muscle

8

Which muscle maintains constant muscle tone to bend the rectum and relaxes to allow defecation?

Puborectalis (aka pubo-rectal sling)

 

Skeletal muscle => under somatic control

 

Most medial part of levator ani (=> most medial part of the pelvic diaphragm)

9

Which structure marks the transition from internal to external anal sphincter?

Pectinate line

Where splanchnopleure meets somatopleure

This is the site of the cloacal membrane (vestigial)

10

What are the boundaries of the inguinal triangle?

  • Lateral edge of the rectus
  • Inferior epigastric artery
  • Inguinal ligament

 

11

List the muscle sof the pelvic diaphragm (2 but kind of 3)

  • Levator ani
    • Pubococcygeous
    • Iliococcygeus
  • Ischiococcygeus

 

 

12

As the testes descends, each layer of the body wall except the _____ contributes to the covering of the spermatic cord

As the testes descends, each layer of the body wall except the  transversus abdominus  contributes to the covering of the spermatic cord

13

Between which landmarks is the largest diameter of the birth canal?

Transverse dimension of the pelvic brim

14

Above the pectinate line:

  • Type of muscle:
  • Innervation:
  • Venous drainage:
  • Lymph drainage:

Below the pectinate line:

  • Type of muscle:
  • Innervation:
  • Venous drainage:
  • Lymph drainage:

Above the pectinate line: endoderm

  • Type of muscle: Smooth
  • Innervation: Visceral, autonomic
    • Pelvic splanchnics
  • Venous drainage: Portal system
  • Lymph drainage: With internal iliac vessels

 

Below the pectinate line: ectoderm

  • Type of muscle: Skeletal (striated)
  • Innervation: General sensory, somatomotor
    • ​Pudendal nerve
  • Venous drainage: Iliac/caval system
  • Lymph drainage: Superficial inguinal nodes

 

 

15

 A women with chronic, severe cramping of the uterus can get relief from severing or anesthetizing which of the following?

 

A. Pudendal nerve

B. Nerve roots in the sacral canal

C. Superior hypogastric plexus

D. Pelvic splanchnic nerves

C. Superior hypogastric plexus

 

Lumbar splanchnics provide sensory innervation to the uterine body and fundus

16

The transversalis fascia contributes to the [layer of covering of the spermatic cord]

The transversalis fascia contributes to the internal spermatic fascia (and deep inguinal ring)

17

[direct/indirect] hernias are lateral to the inferior epigastric artery

Indirect hernias are lateral to the inferior epigastric artery

18

Which part of the pelvis marks the course of the pudendal nerve? 

Ischial spine

19

Which part of the urethra constitutes the membranous urethra?

The part that passes through the UG diaphragm

20

A needle through the vagina can most easily sample peritoneal fluid from which location?

Rectouterine pouch

21

Which of the following is NOT part of the pelvic diaphragm?

  1. Iliococcygeus
  2. Pubococcygeus
  3. Coccygeus
  4. Obturator internus
  5. Puborectalis

d. Obturator internus

 

All others are part of the pelvic diaphragm


22

Where in the anal canal does the epithelium change from GI to skin?

Which type of epithelium is found in each place?

White line

GI = simple columnar 

Skin = stratified squamous

23

Infection in which of the following locations might impair function of the external anal sphincter by interrupting its nerve supply?

 

A. Superficial perineal pouch

B. Ischioanal fossa

C. Deep perineal pouch

D. Rectouterine pouch

E. Pelvic peritoneal cavity

B. Ischioanal fossa

Inferior rectal branches of the pudendal nerve must traverse the ischioanal fosa to reach the external anal sphincter

 

Rectouterine pouch and pelvic cavity have nothing to do with rectal innervation

Perineal pouch relates to the UG diaphragm

24

How does fluid in the superficial perineal pouch drain?

Must flow in between superficial (scarpa's) and deep investing fascia 

25

What kind of muscle is found in the external anal sphincter?

Striated (skeletal) muscle

26

Which structure related to the uterus corrensponds to the male gubernaculum?

Round ligament of the uterus

27

Which layer forms the deep inguinal ring? (Aka beginning of the inguinal canal)

Transversalis fascia

28

What is the best surgical approach for removing a kidney stone to minimize bleeding?

Midline

You will avoid the major veins and arteries, which open into the renal pelvis anteriorly and posteriorly (not midline)

29

Sacrospinus (from 1 to sacrum)

Sacrotuberous (from 2 to sacrum)

30
