Q

Purpose of mesentery?

A
  • Suspends gut organs
  • Pathway for blood, innervation, lymphatics etc to reach the gut
  • Ventral mesentery degenerates during development, except for foregut

16
Q

Movement of external oblique

A
  • Contralateral rotation of the torso
17
Q

Innervation of the external oblique

A
  • thoracoabdominal nerves (T7-T11) and subcostal nerve(T12)
18
Q

What are the attachments of the internal oblique?

A
  • Originates from the inguinal ligament, iliac crest and lumbodorsal fascia
  • inserts into ribs 10-12
19
Q

Internal oblique function

A
  • Bilateral contraction compresses the abdomen, while unilateral contraction ipsilaterally rotates the torso
20
Q

Innervation of intenal obliques

A
  • Thoracoabdominal nerves(T7-T11)
  • Subcostal nerve(T12)
  • Branches of lumbar plexus
21
Q

Directions of the fibres of internal and external obliques

A

Internal - Supero-medial

External - Infero-medial

22
Q

Most superficial anterior muscle

A
  • External oblique
23
Q

Location of internal oblique with respect to the other muscles

A
  • Lies deep to the external oblique

- It is smaller and thinner in structure

24
Q

Attachments of the transversus abdominis

A
  • Originates from the inguinal ligament, costal cartilages 7-12, the iliac crest and the thoracolumbar fascia
  • Inserts into the conjoint tendon, xiphoid process, linea alba and the pubic crest
25
Q

Function of transversus abdominis

A

Compression of abdominal contents

26
Q

Innervation of transversus abdominis

A
  • Thoracoabdominal nerves(T7-T11)
  • Subcostal nerve(T12)
  • Branches of the lumbar plexus
27
Q

Fascia that is deep to the transversus abdominis

A

Transversalis fascia

28
Q

What are the attachments of the rectus abdominis

A
  • Originates from the crest of the pubis

- Inserts into the xiphoid process of the sternum and the costal cartilage of ribs 5-7

29
Q

Functions of the rectus abdominis

A
  • Assists the flat muscles in compressing the abdominal viscera, the rectus abdominis also stabilises the pelvis during walking, and depresses the ribs
30
Q

Innervation of the rectus abdominis

A

Thoracoabdominal nerves(T7-T11)

31
Q

What gives rise to the six pack

A
  • At several places, the rectus abdominis is intersected by fibrous strips, known as tendinous intersections
32
Q

Describe the pyramidalis

A

Is a small triangular muscle, found superficially to the rectus abdominis

It is located inferiorly with its base on the pubis bone, and the apex of the triangle attached to the linea alba

33
Q

Attachments of the pyramidalis

A
  • Originates from the pubic crest and pubic symphysis before inserting into the linea alba
34
Q

Functions of the pyramidalis

A
  • Acts to tense the linea alba
35
Q

Innervation of the pyramidalis

A
  • Subcostal nerve(T12)
