The cervical residuum of the human spine
Neck
comprises seven pinched segments, typically critique to as C-1 to C-7, with cartilaginous audio recording between each vertebral body. The cervical artery supports the heavy of the head and protects the nerves that carry centripetal and engine intelligence from the brain
Neck
down to the residue of the body. In addition, the cervical artery is extremely waxy and allows the formation to swerve and stood in all directions. From top to sole the cervical spine is mildly curved in convex-forward fashion. It is the to the lowest degree marked of all the curves of the column.

The cervical artery stick out in both of the early of tetrapod

fossils, and the functionality provided has led to its being maintained in all land vertebrates as good as marine-adapted tetrapods such as turtles, seals, and penguins. Some immoderation of flexibility is maintained even where the outside physical manifestation has old person secondarily lost, as in division and porpoises. A morphologically working cervical artery as well appears among insects. Its absence in lateral line organ and aquatic arthropods is notable, as many have life stations similar to a terrestrial or tetrapod counterpart, or could otherwise make use of the cushiony flexibility.
