acromioclavicular joint irregular joint between the acromion process of the scapula and the distal clavicle Bones of the face mandible, maxillae, nasal bone, palatine bone and nasal conchae, vomer, zygomatic bone, lacrimal bone, hyoid bone acromion process located on the superior lateral aspect of the spine of the scapula, may be felt on the top of the shoulders coracoid process process above the glenoid cavity that permits muscle attachment insertion of pectoralis minor inferior angle of scapula lowest point of the scapula origin site for teres minor can be palpated medial border of scapula medial edge, next to vertebral column insertion of serratus anterior spine of scapula a long projection dividing the lateral surface of the scapula attachment point for the deltoid and trapezius muscles Borders of Axilla Anterior: Pectoralis Major & Minor Posterior: Scapula, Subscapularis, Teres Major, Latissimus Dorsi Medial: Serratus Anterior, Ribs Lateral Wall: Humerus, Long head of Triceps, Coracobrachialis deltoid -Origin the anterior border and upper surface of the lateral third of the clavicle, acromion, spine of the scapula -Insertion deltoid tuberosity of humerus -Actions shoulder abduction by middle deltoid, flexion by anterior deltoid and extension by posterior deltoid Trapezius -Origin spinous processes of vertebrae C1-T12 Elevates, depresses, retracts, and rotates the scapula; rotates the arm greater tubercle of humerus located on the lateral surface just below the neck and is separated from the lesser by a deep depression called the intertubercular groove attachment for supraspinatus, infraspinatus, and teres minor biceps brachii -Origin =Short head: coracoid process of the scapula. =Long head: supraglenoid tubercle -Insertion Radial tuberosity and bicipital aponeurosis into deep fascia on medial part of forearm -Actions =Flexes elbow, =supinates radioulnar joint in the forearm triceps brachii -Origin=Long head: infraglenoid tubercle of scapula =Lateral head: above the radial sulcus =Medial head: below the radial sulcus -Insertion Olecranon process of ulna-Nerve Radial nerve Actions= Extends forearm, = long head extends,adducts arm, Extends shoulder lateral and medial epicondyles of humerus Medial more prominent caudally Lateral is more rounded on x ray, medial more square Lateral epicondyle is the origin of the extensors of the forearm and the medial is the attachment for the flexors of the forearm cubital tunnel between medial epicondyle and olecranon process ulnar nerve passes through cubital fossa boundaries: pronator teres, brachioradialis, line b/t epicondyles; contains: biceps tendon, brachial artery, median and radial nerves olecranon process of ulna insertion of triceps brachii, can palpate wrist extensors extensor carpi radialis longus extensor carpi radialis brevis extensor carpi ulnaris extensor carpi radialis longus Origin: lateral supracondylar ridge of humerus Insertion: base of metacarpal 2 Action: extends and abducts hand extensor carpi radialis brevis Origin: Lateral epicondyle of humerus Insertion: Base of 3rd metacarpal bone Action: Extension and abduction at wrist extensor carpi ulnaris Origin: Lateral epicondyle of the humerus Insertion: 5th metacarpal Action: Extends the hand wrist flexors flexor carpi radialis, flexor carpi ulnaris, palmaris longus flexor carpi ulnaris Origin: Medial epicondyle of the humerus Insertion: 5th metacarpal Action: Flexes the hand flexor carpi radialis -Origin medial epicondyle of humerus -Insertion Bases of second and third metacarpal bones -Actions Flexion and abduction at wrist palmaris longus -Origin medial epicondyle of humerus (common flexor tendon) -Insertion palmar aponeurosis -Actions wrist flexor finger flexors flexor digitorum superficialis, flexor digitorum profundus, flexor pollicis flexor pollicis longus Origin: Anterior surface of radius, and interosseous membrane Insertion: Distal phalanx of thumb Action: Flexes thumb flexor digitorum superficialis Origin: Medial epicondyle of humerus, coronoid process of ulna, and shaft of radius Insertion: Middle phalanges of fingers 2-5 Action: Flexes hand and middle phalanges of fingers 2-5 flexor digitorum profundus Origin: Anteromedial surface of ulna, interosseous membrane, and coronoid process Insertion: Distal phalanges of fingers 2-5 Action: Flexes distal phalanges finger extensors extensor digitorum, extensor pollicis longus and brevis extensor digitorum Origin: lateral epicondyle of humerus Insertion: by four tendons into distal phalanges of fingers 2-5 Action: prime mover of finger extension extensor pollicis longus Origin: Posterior surface of middle of ulna and interosseous membrane Insertion: Base of distal phalanx of thumb Action: Extension of thumb
