The arm models we used simulated the actions of flexion and extension at the human elbow joint. Standing in the anatomical position, slowly bend your arm at the elbow. The muscle that's producing the force is (bicep or tricep). The contraction type is (concentric or eccentric). The opposite action is (concentric or eccentric contraction). The muscle that's producing the force is (bicep or tricep).

Match the muscles that move the arm with their actions. 1. Prime mover of arm extension 2. Flexes arm 3. Prime mover of arm flexion 4. Extends and adducts arm 5. Medially rotates arm Latissimus dorsi Pectoralis major Triceps brachii (long head) Biceps brachii (long head) Subscapularis

The bones of the forearm (radius and ulna) are hinged to the humerus at the elbow. The biceps muscle connects to the bones of the forearm about 2.15 cm beyond the joint. Assume the forearm has a mass of 2.45 kg and a length of 0.465 m. When the humerus and the biceps are nearly vertical and the forearm is horizontal, if a person wishes to hold an object of mass 7.75 kg so that her forearm remains motionless, what is the force exerted by the biceps muscle?
