Which nerve roots contribute to the median nerve?

Explanation:
The median nerve receives fibers from all five ventral rami from C5 through T1 because it is formed by contributions from two parts of the brachial plexus: the lateral root from C5-C7 and the medial root from C8-T1. When these roots join, the median nerve carries the combined innervation from C5, C6, C7, C8, and T1. That makes its root range C5-T1. The other ranges leave out some of these roots, which is why they aren’t correct: they either miss the lower roots (C8-T1) or the upper roots (C5-C6), depending on the specific range.
