c. The triceps is the prime mover and the anconeus a weak auxistant in of the clbow. 1. When hammering a nail, the (bicops brachiti/ triceps brachii) concentrically contracts on the downswing. c. The (anteriot/posteriot) museles of the elbow are used to raise a water glass. Museles of the Forearm, Wrist, and Hand 1. Pronator Teres a. The proximal attachment of the pronator teres is on the epicondyle of the humerus and the distal attachment on the lateral surface of the (nitius / ulna)). b. As its name implies, this muscle will the pivot joints of the forcarm. 2. Flexor Carpi Radialis, Flexor Carpi Ulnaris, and Palmaris Longus a. These 3 muscles all take their proximal attachments on the (medial/lateral) epicondyle of the humerus and teminate distally just beyond the wrist. b. When these museles contract the hand will be pulied so as to (extend/flex) the radiocarpal joint. c. Located between the flexor carpi radialis and flexor carpi ulnaris is the 3. Flexor Digitorum Superficialis a. Located beneath the flexors of the wrist. Like those muscles, this musele arises from the epicondyle of the humerus and is also anchored to the middle portion of the (rudius / ulna) b. The tendon of the flexor digitorum superficialis divides into ( 2/3/4 ) segments. c. These tendons inset on the (distal / medial) phalanges of the four fingers. d. Thus far, we have noted that the muscles of the anterior forearm all have attachments on the of the humerus and acts as (cxtensors / flexors) of the wrist and fingers. 4. (Deep Anterior Muscles) Flexor Digitorum Profundus and Flexor Pollicus Longus a. The flexor digitorum profundus originates on the upper end of the (radius / ulna) and its lower tendons divides into four branches that pass to the (distal / proximal) phalanges of the four fingers. b. The obvious function of this musele is (extension / flexion) of the fingers. c. The flexor pollicus longus arises from the anterior surface of the (radrus/ ulna) d. When you see the term pollicis in the name of a muscle you will know that it attaches to the thumb The flexor pollicis longus inserts on the phalanx of the thumb. 5. Pronator Quadratus a. This four sided muscle is located on the anterior surface of the (distal / proximal) end of the forea b. When we pronate the forearm, the pronator teres pulls on the upper end of the radius and the pronator pulls on the lower end of that bone. c. The musculature of the anterior forearm will (extend / flex) the wrist and fingers. d. The long muscle that flexes the thumb is the.
