Question

multiple choice question
which region of the body is served by nerves arising from the brachial plexuses?
lower limb
upper limb
skin and muscles of the neck

Explanation:

The brachial plexus is a network of nerves that originates from the cervical and thoracic spinal nerves. Its primary function is to supply the nerves to the upper limb (including the arm, forearm, and hand). The lower limb is served by the lumbosacral plexus, and the skin and muscles of the neck are served by cervical plexus - derived nerves. So the region served by nerves from the brachial plexuses is the upper limb.

Answer:

B. Upper limb
