Question

question 8 (1 point) this brachial nerve is derived from c8 & t1. it innervates the flexor carpi ulnaris, flexor digitorum profundus, adductor pollicis. radial n. ulnar n. axillary n. median n.

Explanation:

The ulnar nerve originates from the C8 and T1 nerve roots. It innervates muscles such as the flexor carpi ulnaris, part of the flexor digitorum profundus (the medial half), and the adductor pollicis. The radial nerve (Radial N.) mainly innervates extensor muscles. The axillary nerve (Axillary N.) is involved with the deltoid and teres minor muscles. The median nerve (Median N.) innervates different forearm and hand muscles (e.g., most of the flexor digitorum superficialis, thenar muscles etc., but not the ones listed here like adductor pollicis which is ulnar - innervated).

Answer:

Ulnar N.
