Question

Quizplus · Accepted Answer

Flexion of the left elbow is a normal response for the biceps deep tendon reflex. Pronation of the left forearm is a normal response for the brachioradialis deep tendon reflex. Supination of the left arm is not a response of any deep tendon reflex. Extension of the left elbow is the normal response of the triceps deep tendon reflex.
