THE ARM ANATOMY COMPLETE A+ SOLUTION

THE ARM ANATOMY COMPLETE A+ SOLUTION upper arm bone, arteries, nerves - >- HUMERUS: shaft (with bicipital groove), head, neck, tuberosities, condyles and epicondyles (medial = trochlea, lateral = capitulum), coronoid fossa (anterior), olecranon fossa (posterior) - ARTERIES: (1) brachial artery - anteromedial in upper arm, moves laterally and anteriorly at elbow to form ulnar and radial arteries (2) profunda brachii arterty - NERVES: median (through carpal tunnel), ulnar ("funny bone"), radial muscles of the upper arm anterior compartment - >- BICEPS BRACHII: elbow flexion, supination, assists in shoulder flexion, o: supraglenoid tubercle and coracoid, i: radial tuberosity and forearm fascia - BRACHIALIS: elbow flexion, o: anterior surface of humerus, i: coronoid of ulna - CORACOBRACHIALIS: assists with shoulder flexion muscles of upper arm posterior compartment - >- TRICEPS BRACHII: elbow extension, o: infraglenoid tubercle, upper lateral and lower medial halves of the posterior humerus shaft, i: olecranon of ulna - ANCONEUS: assists triceps brachii elbow bones and joint type - >- JOINT TYPE: synovial hinge joint - BONES: (1) radius - articulates with capitulum and with raid notch of ulna, distal articulation with ulna, interosseous membrane between radius and ulna shafts (2) ulna - olecranon process and coronoid process, trochlear notch articulates with trochlea elbow ligaments, movements, cubital fossa - >- LIGAMENTS: capsular, medial (ulnar) collateral and lateral (radial) collateral - MOVEMENTS: flexion and extension (pronation and supination occur at radioulnar joints) - CUBITAL FOSSA: anterior, inverted triangle, contains median and radial nerves, brachial artery and its derivatives and tendon of biceps brachii radioulnar joint type and articulations - >-
