The C8 and T1 nerve roots are part of the brachial plexus, a complex network of nerves that arises from the spinal cord in the neck region. The brachial plexus is formed by the ventral rami of the C5 to T1 spinal nerves. The C8 and T1 nerve roots emerge from the intervertebral foramina, which are narrow openings between adjacent vertebrae.

| Function | C8 Nerve Root | T1 Nerve Root | | :--- | :--- | :--- | | | Finger flexors (FDS, FDP to middle/ring/little fingers), hand intrinsics (interossei, lumbricals 3&4), thumb adductor (adductor pollicis), long thumb flexor (FPL). | Hand intrinsics (thenar muscles – via median nerve; hypothenar & interossei – via ulnar nerve). T1 contributes significantly to median-innervated thenar bulk. | | Sensory | Medial forearm (medial antebrachial cutaneous), ring and little fingers (ulnar distribution, dorsal and palmar aspects). | Medial arm (medial brachial cutaneous) and variable contribution to medial forearm; minimal discrete autonomous zone but overlaps C8. | | Reflex | No deep tendon reflex is purely C8/T1. The finger jerk (flexor reflex) is partly mediated by these roots. | Same as C8. | The C8 and T1 nerve roots are part
The primary role of these roots is to control the flexors of the wrist and fingers and the intrinsic muscles of the hand. The C8 level corresponds to the region in
