THE UPPER LIMBS
Structures (bones): Totals Humerus (upper arm): 1 in each arm 2 Ulna and Radius (forearm): 2 in each arm 4 Carpals (wrist): 8 in each arm 16 Metacarpals (hands): 5 in each arm 10 Phalanges (fingers): 14 in each arm 28 .Total Number of Bones 60

THE UPPER LIMBS
Function: Attachment sites for muscles of the arms
and hands

THE UPPER LIMBS
Joints of the Upper Arms: No point of connection to axial skeletal system
Has all types of freely-movable joints: Saddle: carpal and metacarpal bones of thumb
Ball and socket: shoulder
Pivot- rotation only: proximal end of radius and ulna
Hinge- up and down movement in one plane: elbow
Gliding- sliding and twisting: wrist
Condyloid- movement in different planes but not rotations: between metacarpals and phalanges
