The adult human skeleton is composed of 206 bones, divided into the axial skeleton (80 bones) and the appendicular skeleton (126 bones). The axial skeleton includes the skull, vertebral column, and ribcage, while the appendicular skeleton consists of bones in the upper and lower limbs. These bones serve essential functions such as structural support, protection, and enabling movement.

sacrum (5 fused bones), and coccyx (4 fused bones)

- *Ribcage (24 bones)*: Sternum (3 bones) and ribs (24 bones, 12 pairs)

*2. Appendicular skeleton (126 bones)*

- *Upper limbs (64 bones)*: Scapula (2 bones), humerus (2 bones), radius (2 bones), ulna
(2 bones), carpals (16 bones), metacarpals (10 bones), and phalanges (28 bones)

movement.
