Question

Select the best answer or answers from the choices given: The arm muscle that both flexes the elbow and supinates the forearm is the (a) brachialis, (b) brachioradialis, (c) biceps brachii, (d) triceps brachii.

Expert Solution

Step 1

The muscular system helps in the basic structure of the body with the skeletal system and maintains the posture and synthesizes proteins and several other compounds. There are 700 types of muscles found in the body.

Step 2

The muscle that supinates the forearm and flexes the elbow also is the Biceps brachii. It is the muscle of the arm that forms the double-headed muscle since it connects both the elbow and the shoulder. The short head starts from the top of the scapula.

Hence the correct option is 'c'.
