Editor's Notes
- #2 Divided into 4 parts. And each part has its own branches to different parts of the upper extremities
- #5 Neither of the C6 muscle is pure Neither of the C6 muscle tests is pure; the wrist extensor group is innervated partially by C6 and partially by C7, while the biceps has both C5 and C6 innervation
- #7 Neither of the C6 muscle is pure
- #8 ask the patient to make a fist and to flex his wrist as you resist against the palmar aspect of his closed fist.
- #9 To test finger extension, press on the dorsum of the patient’s extended fingers Sensation is supplied to the middle finger by C7. Occasionally, middle finger sensation is also supplied by C6 and C8.
- #10 test finger flexion, curl or lock your fingers into the patient’s flexed fingers and try to pull them out of flexion
- #11 C8 supplies sensation to the ring and little fingers of the hand and to the distal half of the forearm’s ulnar side. The ulnar side of the little finger is the purest area for ulnar nerve sensation (predominantly C8)
