The median nerve originates from the lateral and medial cords of the brachial plexus, and has contributions from ventral roots of T1 ( medial cord ).
The median nerve originates from the lateral and medial cords of the brachial plexus, and has contributions from ventral roots of T1 ( medial cord ).
The spinal roots of C8 and T1 then merge to form the lower trunk, anterior division, medial cord, and finally produce the ulnar nerve.
The ulnar nerve originates from the C7 fibres ) which form part of the medial cord of the brachial plexus, and descends on the posteromedial aspect of the humerus.
Regardless of their final innervation, the nerves that reach the thenar muscles arise from the C8 and T1 roots, pass through the lower trunk of the plexus, and then through the medial cord of the plexus.
