What is a terminal branch of the brachial plexus?

• A. Musculocutaneous Nerve
• B. Median Nerve
• C. Radial Nerve
• D. Axillary Nerve

Answer: (D)

Terminal branches are the final nerves that leave the brachial plexus to supply the upper limb. The five standard terminal nerves are musculocutaneous, axillary, radial, median, and ulnar. The axillary nerve is one of these terminal branches, arising from the posterior cord and primarily innervating the deltoid and teres minor, with sensory input over the skin of the shoulder region. So it is a correct example of a terminal branch. The other nerves listed are also terminal branches, each with its own distribution.
