Question

What are the parts of the appendicular skeleton?

Answer 1

Of the 206 bones in the human skeleton, the appendicular skeleton comprises 126. Functionally it is involved in locomotion (lower limbs) of the axial skeleton and manipulation of objects in the environment (upper limbs).

The appendicular skeleton forms during development from cartilage, by the process of endochondral ossification.

The appendicular skeleton is divided into six major regions:

Pectoral girdles (4 bones) - Left and right clavicle (2) and scapula (2).Arms and forearms (6 bones) - Left and right humerus (2) (arm), ulna (2) and radius(2) (forearm).Hands (54 bones) - Left and right carpals(16) (wrist), metacarpals (10), proximal phalanges (10), intermediate phalanges (8) and distal phalanges (10).Pelvis (2 bones) - Left and right hip bone(2).Thighs and legs (8 bones) - Left and right femur (2) (thigh), patella (2) (knee), tibia (2) and fibula (2) (leg).Feet and ankles (52 bones) - Left and right tarsals (14) (ankle), metatarsals (10), proximal phalanges (10), intermediate phalanges (8) and distal phalanges (10).
