This article has multiple issues. The intervertebral discs are fibrocartilaginous cushions serving as the spine's shock absorbing system, which protect the vertebrae, brain, and other structures. They are responsible for the nodding and rotation movements of the head. Learn more about our spine research at MayfieldFoundation. The brain sends motor messages to the limbs and body through the spinal cord allowing for movement.
The seven cervical vertebrae are numbered C1 to C7.
The neck has the greatest range of motion because of two specialized vertebrae that connect to the skull. The cervical spine is made up of 7 vertebrae. The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis.
The cervical spine has 7 stacked bones called vertebrae, labeled C1 through C7.
Cervical Spine Anatomy
The top of the cervical spine connects to the skull, and the bottom connects to.
The neck cervical and low back lumbar regions have a slight concave curve, and the thoracic and sacral regions have a gentle convex curve Fig.
The transverse processes are of considerable size, their posterior roots are large and prominent, while the anterior are small and faintly marked; the upper surface of each has usually a shallow sulcus for the eighth spinal nerve, and its extremity seldom presents more than a trace of bifurcation.

The intervertebral foramen neural passageways are relatively large but nerve root compression is more common than in the thoracic spine. Costal facets superior inferior transverse Uncinate process of vertebra.
This part of the vertebral canal is of considerable size, much greater than is required for the accommodation of the spinal cord.
Lay summary — ScienceDaily May 6, Sometimes the spinal cord can react without sending information to the brain.
The upper back, or thoracic spine, has 12 vertebrae, labeled T1- T Information and pictures of the spine and spinal cord showing C1 to S5 Fig 1. Lateral labeled diagram of the human vertebral spinal column. In anatomy, the atlas (C1) is the most superior (first) cervical vertebra of the spine.

It is named for the Atlas of Greek mythology, because it supports the globe of.
This groove transmits the vertebral arterywhich, after ascending through the foramen in the transverse process, winds around the lateral mass in a direction backward and medially to enter the vertebrobasilar circulation through the foramen magnum ; it also transmits the suboccipital nerve first spinal nerve.
Each spinal nerve has two roots Fig. Inside the disc is a gel-filled center called the nucleus, much like a tire tube Fig. Vertebral Column. Views Read Edit View history.
