Study Notes
Radial Nerve
- The radial nerve is NOT primarily responsible for innervating the pronator teres muscle.
- Damage to the radial nerve does NOT directly affect pronation of the forearm.
- Numbness or tingling on the medial aspect of the hand is NOT a symptom associated with radial nerve injury.
- The extensor digitorum communis muscle is innervated by the radial nerve and is responsible for extending the elbow joint.
- The radial nerve is responsible for wrist drop and finger-drop with weak radial deviation of the wrist.
- The radial nerve runs in the spiral groove of the humerus in the arm.
- The flexor carpi radialis muscle does NOT receive innervation from the radial nerve.
- The radial nerve emerges between the two heads of the pronator teres muscle to enter the forearm.
