Its primary function is the flexion of the fingers, and this is used as the clinical test for C8 integrity, in conjunction with the finger jerk reflex. [ 4 ] The particular muscles receive innervation from C8 [ 3 ] (shown by specific nerve and spinal nerve segments; muscles in italics only have a minor contribution from C8) :
The cervical spinal nerve 6 (C6) is a spinal nerve of the cervical segment. [1] It originates from the spinal column from above the cervical vertebra 6 (C6). The C6 nerve root shares a common branch from C5, and has a role in innervating many muscles of the rotator cuff and distal arm, [2] including: Subclavius; Supraspinatus; Infraspinatus ...

The posterior divisions; The anterior divisions; The thoracic nerves; The lumbosacral plexus; The sacral and coccygeal nerves; The sympathetic nerves. The cephalic portion of the sympathetic system; The cervical portion of the sympathetic ...
The cervical spinal nerve 2 (C2) is a spinal nerve of the cervical segment. [1] It is a part of the ansa cervicalis along with the C1 and C3 nerves sometimes forming part of superior root of the ansa cervicalis. [2] it also connects into the inferior root of the ansa cervicalis with the C3. [2]
The cervical spinal nerve 5 (C5) is a spinal nerve of the cervical segment. [1]It originates from the spinal column from above the cervical vertebra 5 (C5). It contributes to the phrenic nerve, long thoracic nerve, and dorsal scapular nerve before joining cervical spinal nerve 6 to form the upper trunk, a trunk of the brachial plexus, which then forms the lateral cord, and finally the ...
Cervical spinal nerve 4, also called C4, is a spinal nerve of the cervical segment. It originates from the spinal cord above the 4th cervical vertebra (C4). It contributes nerve fibers to the phrenic nerve , the motor nerve to the thoracoabdominal diaphragm .
The cervical spinal nerve 7 (C7) is a spinal nerve of the cervical segment. [1] It originates from the spinal column from above the cervical vertebra 7 (C7). It runs through the interspace between the C6 and C7 vertebrae.
The superior cervical ganglion (SCG) is the upper-most and largest [1] of the cervical sympathetic ganglia of the sympathetic trunk. [1] [2] It probably formed by the union of four sympathetic ganglia of the cervical spinal nerves C1–C4. [1] It is the only ganglion of the sympathetic nervous system that innervates the head and neck.
