Actions: Pronation; flexion of forearm (weak) flexor carpi radialis (superficial) O: Common flexor tendon from the medial epicondyle of the humerusI: Base of the 2nd (sometimes 3rd) metacarpalInn: Median nerveBlood supply: Radial arteryActions: Flexion of wrist (with FCU); radial deviation (...
Superficial muscle that rapidly or forcefully supinates the forearm and synergistically enhances elbow flexion with the brachialis muscle. Brachialis muscle Deep muscle that is the prime mover of elbow flexion. Coracobrachialis muscle Deep and medial muscle that flexes and adducts the arm at the sho...
As soon as the muscle had contracted and pulled on a bone, that would be it, with no way to move the bone back again. This problem is solved by having muscles in pairs, called antagonistic muscles . For example, your elbow joint has two muscles that move your forearm up or down. ...
pronation of forearm Golfers/baseball elbow medial epicondylitis, pain from elbow to wrist, inflammation/overuse of wrist flexors radial nerve What nerve innervates the posterior compartment? lateral epicondyle What is the origin of posterior muscles?
