Question 2

Annexation of outermost body wall muscles in superior limb

Answer 2

levator scapulae
serratus anterior
rhomboideus major
rhomboideus minor

Question 3

Proximal limb muscles

Answer 3

pec major

lats

Question 4

Nerves

Ventral Ramus

Answer 4

Anterior Divisions
Posterior Divisions
Plexus formation

Question 5

Limb Muscles
from primitive vertebrate
to premammalian limb
to Mammalian limb

Answer 5

Essentially, the elevator (dorsal) muscles and depressor (ventral) muscles compartments are same in all limbs. Until the Mammalian limb where the lower limb is turned in. As a result, the posterior compartment of lower limb is actually anterior compartment vis a versa
