composed of wrist, palm, dorsum of hand, and fingers
Hand:
Pectoral girdles AKA
shoulder girdles
attach the bones of the upper limbs to the axial skeleton (the pectoral girdle is a component of the appendicular skeleton)
Pectoral girdles (AKA shoulder girdles) attach the bones of the upper limbs to
the axial skeleton (the pectoral girdle is a component of the appendicular skeleton)
Human body has two pectoral girdles, each comprising a (2 things)?
They are held in place by?
