The vertebral column is often used as a marker of human anatomy. This includes: At C1, base of the nose and the hard palate; At C2, the teeth of a closed mouth; At C3, the mandible and hyoid bone; At C4, the common carotid artery bifurcates. From C4–5, the thyroid cartilage [10] From C6–7, the cricoid cartilage [10]
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 ...
The posterior division of the third cervical is intermediate in size between those of the second and fourth. Its medial branch runs between the Semispinalis capitis and cervicis, and, piercing the Splenius and Trapezius, ends in the skin.
The middle cervical ganglion is presumed to represent the union of the two sympathetic ganglia corresponding to cervical segments C5–C6 since its gray rami communicantes usually join the cervical spinal nerves C5–C6, however, the ganglion sometimes also contributes gray rami communicantes to spinal nerves C4 and C7.

The supraclavicular nerve is a cutaneous (sensory) nerve of the cervical plexus that arises from the third and fourth cervical (spinal) nerves.It emerges from beneath the posterior border of the sternocleidomastoid muscle, then split into multiple branches.
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 .
