why can fluid not flow from superficial abdomen to leg?

A

scarpas fascia fuses with fascia lata of lower limb

17
Q

What is the innervation, origin, insertion, function of the external oblique?

A

inn: anterior rami of T7-T12
origin: serratus anterior ribs
insertion: linea alba
function: compress abdomen, rotate, retain posture

18
Q

A

inn: T7-L1, iliohypogastric, ilioinguinal
origin: iliac crest
insertion: lina alba
function: compress/lateral flexion

19
Q

What is the innervation, origin, insertion, function of the transversus abdominis?

A

inn: T7-L1, iliohypogastric, ilioinguinal
linea alba, lower ribs who cares
compresses

20
Q

What is the innervation, origin, insertion, function of the rectus?

A

inn T7-T12

flex abdomen, f

21
Q

what are some features of the external oblique? 2

A

fibers run like hands in your pockets

lower part rolled to make inguinal ligament

22
Q

features of internal oblique? 2

A

makes conjoin tendon with TA

fibers make cremaster muscle

23
Q

features of trasnversus abdominis? 1

A

contributes to conjoin tendon

24
Q

what role do abdominal muscles play in respiration?

A

active exhalation

25
what is the recuts sheath?
the aponeurosis of the other 3 muscles covering the recuts abdominis
26
what is the arcuate line?
the point where the rectus sheath is all anterior EO-always anterior IO-top 3/4 is split, bottom is anterior TA-top 3/4 is post, bottom is anterior
27
what is the origin of the thoracoabdominal nerves? function? runs where?
T7-T11, sensory to these areas and motor to IO and TA | runs between these
28
function and origin of subcostal nerve?
T12, sensory to superior to iliac crest
29
function and origin of iliohypogastric?
L1 motor: IO, TA sensory: skin in piubic region
30
function and origin of ilioinguinal?
L1 motor: IO, TA sensory: anterior balls, skin on medial thigh
