Appendicular Skeletal System• Composed of 126 bones• The appendicular skeleton is divided into six major regions:• 1) Pectoral Girdles (4 bones) - Left and right Clavicle (2) and Scapula
(2).• 2) Arm and Forearm (6 bones) - Left and right Humerus (2) (Arm),
Ulna (2) and Radius (2) (Fore Arm).• 3) Hands (58 bones) - Left and right Carpal (16) (wrist), Metacarpal
(10), Proximal phalanges (10), Middle phalanges (8), distal phalanges (10), and sesamoid (4).
• 4) Pelvis (2 bones) - Left and right ilium (2).• 5) Thigh and leg (8 bones) - Femur (2) (thigh), Tibia (2), and Fibia (2)
(leg).• 6) Feet (48) - Tarsals (14) (ankle), Metatarsals (10), Proximal
phalanges (10), middle phalanges (8), distal phalanges (10), and sesamoid (4).

Review Terms• Process:• A prominent projection on a bone• Fossa: • A relatively deep pit or depression• Border:• An outline of a bone• Notch: • A groove/concaved curvature• Angle: • Convex curvature• Tubercle: • a small knoblike process• Condyle: • a rounded process that usually articulates with another bone• Epicondyle:• a projection situated above a condyle
