what is the biceps brachii flex the elbow(humeroulnar joint)Supinate the forearm(radioulnar joint)flex the shoulder(glenohumeral jointP tuberosity of the radius and aponeurosos of the biceps brachii shorthead:coracoid process of scapula. Longhead:Supralenoid tubercle of scapula biceps brachii lie superficially on the anterior arm. long head and short head merge to form a long oval belly.primary muscle of forearm supination. easily palpable
what is the triceps brachii all heads extend the elbow(humeroulnar joint)LongHead:extend the shoulder(glenohumeral jnt)Adduct the shoulder(g/h jnt) Olecranon process of the ulna LongHead:Infraglenoid tubercle of the scapula.Lateral Head:Posterior surface of proximal 1/2 of humerus. MedialHead:Posterior surface of distal 1/2 of humerous Only muscle located on posterior arm.Creating an extention at the elbo and shoulder. it is antagonist at both these joints to the Bicep Brac. 3 heads, long, lateral medial.
what is the brachialis flex the elbow humeroulnar joint tuberosity and coronoid process of ulna distal half of anterior surface of humerus is a strong elbow flexor that lies deep to the biceps brach. helps the biceps to bulge further from the arm, making it the biceps best friend.
what is the brachioradialis flex the elbow/humeroulnar jnt assist to pronate and supinate the forearm when these movements are resisted styloid process of radius lateral supracondylar ridge of humerus superficial on the lateral side of forearm.forms a dividing line of flexors and extensors of wrist and hand. runs the length of forearms not cross the wrist joint.
what is the supinator supinate the forearm radioulnar joints lateral surface of proximal shaft of the radius radial collateral ligament annulanr ligament/supinator crest of the ulna located on lateral side of elbow. short supinator is deep to 4arm extensors and superficial to the head of radius.it supinates the 4arm & is antagonist to the pronator teres
what is the pronator teres pronate forearm(radoiulnar joints. assist to flex elbow humeroulnar joint middle of lateral surface of the radius medial epicondyle of humerus, common flexor tendon and coronoid process of the ulna anterior surface of the 4arm, round p teres is tucked between the brachioradialis and 4arm flexors. antagonist to the biceps brachii and supinator (carry bowl of soup)spill a bowl of soup
what is the pronator quadratus pronate the forearm radioulnar joints lateral anterior surface of distal radius medial anterior surface of distal ulna capable pronator. transverse fibers lie deep to the flexor tendons and major nerve and blood vessels of anterior forearm. location of the radial artery. pulse
