Document Summary

The upper limb bones: girdle - clavicle and scapula, humerus - arm, radius and ulna - forearm, carpal bones, bones of hand. The shoulder girdle (or pectoral girdle: consists of 2 bones, scapula (shoulder blade, clavicle (collar bone) Lecture #7 - bones of the upper limb. Clavicle: s-shaped stout bone, connects sternum with scapula. Joint between sternum and clavicle is the only articular attachment of the upper limb to axial skeleton: is strut" - holds shoulder up and away from rib cage. Humerus: head - round, 1/3 of a sphere. Articular surface that joins glenoid fossa in forming shoulder joint. Articulates with proximal surface of head of radius: trochlea - medial condyle shaped like a pulley, medial epicondyle and lateral epicondyle - widest part of humerus (funny bone) Origins of flexor and extensor muscles of forearm, respectively: coronoid fossa - anterior depression, proximal to condyles, olecranon fossa - posterior depression, proximal to condyles.
