Final answer:
The medial antebrachial cutaneous nerve receives sensation from the medial side of the forearm. It arises from the medial cord of the brachial plexus and transmits sensory information to the central nervous system.
Step-by-step explanation:
The medial antebrachial cutaneous nerve is responsible for receiving sensation from the medial aspect of the forearm. This nerve arises from the medial cord of the brachial plexus. Its sensory distribution includes the skin over the anterior and medial surfaces of the forearm, extending down to the base of the palm. The sensitivities collected by the medial antebrachial cutaneous nerve, including touch, pain, and temperature, are transmitted to the central nervous system where they are processed. The brachial plexus is a network of nerves formed by the anterior rami of spinal nerves C5 through T1, and it includes other nerves such as the axillary, radial, ulnar, and median nerves. While the median nerve is often associated with conditions like Carpal Tunnel Syndrome, the medial antebrachial cutaneous nerve is distinct and does not pass through the carpal tunnel.
