The cervical spinal nerve 6 (C6) is a spinal nerve of the cervical segment.

Included are the joint complexes of the upper three cervical segments, the dura mater, and spinal cord.

A catheter was inserted intrathecally in the subarachnoid space to the level of the fourth or fifth cervical segment.

As a result, medial vestibulospinal fibers run down only to the cervical segments of the cord.

The cords extend from the cervical segments to the sacral segments of the embryo.

There is one disc between each pair of vertebrae, except for the first cervical segment, the atlas.

The atlas is a ring around the roughly cone-shaped extension of the axis (second cervical segment).

The ascending portion of the cervical segment occurs distal to the bulb, when the vessel walls are again parallel.

The cervical spinal nerve 4 (C4) is a spinal nerve of the cervical segment.

The cervical spinal nerve 7 (C7) is a spinal nerve of the cervical segment.
