Term

What are the subdivisions of the abdominal wall?

 

Definition

Musculoaponeurotic=

Anterior wall,
Right Lateral wall,
Left Lateral wall,

But because lateral and anterior wall have indefinite boundaries it is called the anterolateral wall.


Posterior wall = Has lumbar vertebral column aswell as musculoapneurotic components.

 

 

Term

What are the boundaries of the anterolateral abdominal wall?

 

(superior/inferior)

Definition

Superior:

7th-10th rib cartillages, xiphoid process of sternum

 

Inferior:

inguinal ligament and sup. margins of anterolateral pelvic girdle (iliac crests, pubic crests and pubic symphysis)

Term
Describe the subcutaneous tissue above and below the umbilicus.
Definition

Aobve the umbilicusconsistent with that of most regions, here the thorax, one layer.


INferior to the umbilicus there are two layers, the superficial fatty layer (CAMPER FASCIA) and the deeper membranous layer, reinforced with collagen/elastic fibres (SCARPA FASCIA)

***

(Membranous layer continues as Colles fascia into the perineal region but not the thighs)

Term
What is the rectus sheath and where is it?
Definition

Between the MCL and the midline.

 

The sheet like aponeurosis of the abdominal muscles (external oblique, internal oblique and transversus abodominus) form the tough aponeurotic tendinous rectus sheath.

Term
What is the linea alba and where is it?
Definition

It is  the 'midline raphe' extending from the xiphoid process of the sternum to the pubic symphysis.


Where the aponeurosis of the anterolateral muscles, superficial and deep, from each side of the body meet/interweave.

 

Term
What two muscels are contained within the rectus sheath?
Definition

Rectus abdominis (large)

Pyramidalis (small)

Term
What are the attachments of the external oblique muscle?
Definition

Origin: External surfaces of 5th-12th ribs.



Insertion: Linea alba, pubic tubercle and anterior half of iliac crest.
