The medial cord is formed by the anterior division of the inferior trunk.
It contains portions of nerves C8-T1.
The medial cord is present in our neck and is a part of the brachial plexus. It is formed by the anterior division of the lower trunk. It is called the medial because it is medial to the axillary artery.
The medial cord leads to the formation of the medial pectoral nerve, medial cutaneous nerve of the arm, and medial cutaneous nerve of the forearm.
The nerves labeled as C refer to the nerves affecting the motor system in our neck and upper limb. Thus nerves from C8 work for the motor conventions of our upper limb and neck.
The nerves labeled as T are spread over our chest, shoulders, and hands. Thus, the nerve T1 works in the upper part of our body.
