upper limb

Which one of the following is not a part of the boundaries of the axilla?. Intertubercular (bicipital) groove of the humerus. Pectoralis minor muscle. Subscapularis muscle. Ribs. Brachial plexus (brachial plexus is not a boundary of the axilla).

Which one of the following statements about the components of the arm is not correct?. The only bone in the brachium is the humerus. The biceps brachii and the triceps brachii are located on opposite sides of the humerus. The cephalic and basilic arteries are superficial arteries in the arm, and the brachial artery is a deep artery that accompanies the brachial vein. (there are no cephalic and basilic arteries, they are veins). The nerves in the arm are all branches of the brachial plexus. The coracobrachialis muscle, which is located in the arm, acts primarily on the shoulder joint.

Which of the following statements about the forearm is not correct?. The bones in the forearm are the radius and the ulna. The muscles of the forearm are divided into anterior and posterior compartments by the radius, the ulna, and an interosseous membrane. Muscles in the forearm generally act on the wrist, the hand, and the fingers. The anterior muscles in the forearm are extensors, and the posterior muscles are flexors. (anterior muscles are flexors, the posterior muscles are extensors). The brachioradialis muscle acts on the elbow rather than on the wrist or hand.
