Q

Thoracic Body Wall:

Lateral Musculature: Outermost Layer (2)

Q

Thoracic Body Wall:
Lateral Musculature: Internal Layer (4)
don’t get DIS’T

A

Internal Layer:
Transversus Thoracis Muscles- depresses ribs
Innermost intercostal muscles- stiffen chest to prevent paradoxical motion during descent of the diaphragm; move the ribs
subcostal muscles-depress ribs
diaphragm- increase volume of thoracic cavity for inspiration

Q

Innervation of Thoracic Wall:
VIP
V–> I & P.

A

Ventral Ramus:
-InterCostal Nerves
–Main Branch
–Collateral Branch (which break off main branch)
–Cutaneous Branches
—lateral cutaneous (side branch to skin)
—anterior cutaneous ( front branch to skin)
PHRENIC NERVE- ventral rami still, but comes from neck bc of embryonic development story.
