Final answer:
The lateral cutaneous nerve of the forearm is the continuation of the musculocutaneous nerve, which carries both sensory and motor fibers from the brachial plexus.
Step-by-step explanation:
The lateral cutaneous nerve of the forearm is the continuation of the musculocutaneous nerve.
This nerve is part of the brachial plexus and contains fibers that are responsible for cutaneous sensation in the arm, as well as motor fibers that innervate muscles.
The musculocutaneous nerve primarily innervates muscles in the anterior compartment of the arm and continues as the lateral cutaneous nerve to provide sensory functions to the skin of the forearm.
