6.3 Appendicular Skeleton* 126 bones * primary function = movement * consists of: limb bones (arms/legs) and their girdles (shoulder/hip)
A. Pectoral Girdle * shoulder * attaches the upper limbs to the trunk
1. clavicles - collarbones5
2. scapulae - shoulder blades
B. Upper Limb (Arm)
1. humerus – upper arm
2. radius – forearm (thumb side)3. ulna – forearm (little finger side)
4. Hand a. carpals = wrist (8)
Dorsal View Palmar View2 rows of 4: * proximal row (thumb little finger) = scaphoid, lunate, triquetrum, pisiform Dorsal View Palmar View
Dorsal View Palmar View* distal row (thumb little finger) = trapezium, trapezoid, capitate, hamate Dorsal View Palmar View
Carpal Bones (Right) Dorsal View Palmar View
2. metacarpals = palm (5 each hand)3. phalanges = fingers (14 each hand) * each digit (finger) has 3: proximal, middle, distal phalanx * thumb has only 2: proximal, distal phalanx distal phalanx middlel phalanx proximal phalanx phalanges metacarpal bones carpal bones ulna radius
C. Pelvic Girdle * attaches the lower limbs to the trunk

Focus on the Pectoral Girdle
The Skeleton System Introduction The Axial Skeleton The Appendicular Skeleton.
Pectoral and Pelvic Girdle and Limbs. Pectoral Girdle Includes 2 clavicles & 2 scapula Forms incomplete ring Provides attachment for muscles that move.
Appendicular Skeleton. 126 bones – suspended by girdles from axial skeleton Designed for movement Pectoral girdle – 4 bones Upper extremity -Arm – 1 bone.
