NURSING 2LA2 Lecture Notes - Lecture 3: Electromyography, Scaphoid Bone, Median Nerve
Document Summary
Tinel"s sign when you run your finger along the nerve you will get a radiating pain. Phalen"s test, force flexion for 60 seconds dorsal surface of two hands together. Electromyography reveals abnormalities in the thenar muscles, stimulated, 40-60 m/sec. If less conduction velocity and longer time (latency) of stimulation = problem with median nerve. Pisiform hamate, tendon runs over those two to form ewons tunnel. Recurrent branch of median nerve courses backwards to get to innervate thenar muscle after passing through carpal tunnel. So superficial that a fall may cause a lesion to it ^ Musculocutaneous- muscles of the arm, sensory of lateral aspects of the forarm. Median- muscles of the forearm except for the medial aspect which is innervated by the ulnar, sensory to thumb, palm, up to half og the ring finger excluding the pinky and the other half of the ring.
