Cervical Spine Anatomy (Neck) Vertebrae and Cervical Spinal Nerves. The cervical spine (sometimes abbreviated as c-spine in the medical world) begins at the base of the skull. Seven vertebrae make up the cervical spine with eight pairs of cervical nerves. The individual cervical vertebrae are abbreviated C1, C2, C3, C4, C5, C6, and C7. The cervical nerves are also abbreviated; they are C1 through C8.

Cervical Vertebrae The cervical spine is made up of two anatomically and functionally different segments. These two segments work together to produce rotation, lateral flexion, flexion and extension of the head and neck. It is made up of 7 vertebrae.The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively.he Atlas, C1, is the topmost vertebra, and along with the Axis; forms the joint connecting the skull and spine. Its chief peculiarity is that it has no body, and this is due to the fact that the body of the atlas has fused with that of the Axis.

Atlas At the cervical region the spinal column is further classified into an upper and lower cervical region. The atlas is one of the two upper cervical vertebrae, also known as C1, which is the topmost vertebra of the spinal column. It is the vertebra that is in contact with the occipital bone, a flat bone located at the back portion of the head.

Cervical Spine Anatomy The upper cervical spine consists of the atlas (C1) and the axis (C2). These first 2 vertebrae are quite different from the rest of the cervical spine (see the image below). The atlas articulates superiorly with the occiput (the atlanto-occipital joint) and inferiorly with the axis (the atlantoaxial joint).ross Anatomy.

- Fig. 1: Sagittal view of the cervical spine. (larger view). The cervical spine is comprised of seven vertebrae-C1, C2, C3, C4, C5, C6, C7 (often noted as C1-C7) - that begin at the base of the skull and extend down to the thoracic spine. Unlike the first two cervical vertebrae, the remaining five cervical vertebrae, C3 through C7, are constructed more similarly to the rest of the spine, with three joints making up each vertebral segment (a disc in the front and two facets joints in the back).

- The human vertebral column usually consists of 33 vertebrae; the upper 24 are articulating vertebrae, separated by intervertebral discs and the lower nine are fused, five fused in the sacrum and four in the coccyx.ertebrae are defined by the regions of the vertebral column that they occur in. Cervical vertebrae are those in the neck area. With the exception of the two sloth genera (Choloepus and Bradypus) and the manatee genus, (Trichechus), all mammals have seven cervical vertebrae.

Seventh cervical vertebra Cervical vertebrae. In vertebrates, cervical vertebrae (singular: vertebra) are the vertebrae of the neck, immediately below the skull. Thoracic vertebrae in all mammalian species are those vertebrae that also carry a pair of ribs, and lie caudal to the cervical vertebrae.

Vertebral column The upper cervical spine has a curve, convex forward, begins at the second cervical vertebra the axis at the apex of the odontoid process known as the dens, and ends at the middle of the second thoracic vertebra; it is the least marked of all the curves.he sides of the vertebral column are separated from the posterior surface by the articular processes in the cervical and thoracic regions, and by the transverse processes in the lumbar region.

The Vertebral Column The vertebral arch refers to the lateral and posterior parts of the vertebrae. With the vertebral body, the vertebral arch forms an enclosed hole, called a vertebral foramen. The foramina of the all vertebrae line up to form the vertebral canal, which encloses the spinal cord.he vertebral column (also known as the backbone or the spine), is a column of approximately 33 small bones, called vertebrae. The column runs from the cranium to the apex of the coccyx, on the posterior aspect of the body.

Description Atlanto-axial joint. Search. The atlanto-axial joint is a joint between the first and second cervical vertebrae; the Atlas and Axis. It is a complex joint made up of three synovial joints and constitutes the most mobile articulation of the spine.otions Available. Rotation is the primary movement at this joint - 50% of cervical rotation (50°) comes from the atlanto-axial articulation. This is allowed by the pivot articulation between the odontoid process of the axis and the ring formed by the anterior arch and the transverse ligament of the atlas.

Seventh cervical vertebra In humans, cervical vertebrae are the smallest of the true vertebrae, and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process, through which passes the vertebral artery.The remainder of this article focuses upon human anatomy.y convention, the cervical vertebrae are numbered, with the first one (C1) located closest to the skull and higher numbered vertebrae (C2-C7) proceeding away from the skull and down the spine. The general characteristics of the third through sixth cervical vertebrae are described here.

A Patient's Guide to Cervical Spine Anatomy The atlas is the first cervical vertebra - the one that sits between the skull and the rest of spine. The atlas does not have a vertebral body, but does have a thick forward (anterior) arch and a thin back (posterior) arch, with two prominent sideways masses.

- The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles, two laminae, and seven processes. The laminae give attachment to the ligamenta flava.pecific to the cervical vertebra is the transverse foramen, (also known as foramen transversarium). This is an opening on each of the transverse processes which gives passage to the vertebral artery and vein and a sympathetic nerve plexus.

The Intervertebral Foramen and Spinal Stenosis The word foramen is the singular form, while foramen is the plural form. The intervertebral foramen is an opening made by two adjacent, stacked vertebrae. In the spinal column, stacking occurs down the front part of the bones (called the bodies). Behind the body of a vertebra is a ring of bone. Looking at a vertebra from either side, the body and ring combination make an arch-like shape. A hole is created by the meeting of the pillars of the arch with the bone below. This hole is the intervertebral foramen.

Vertebra On the cervical vertebrae other than the atlas, the anterior and posterior tubercles are on either side of the transverse foramen on each transverse process. The anterior tubercle on the sixth cervical vertebra is called the carotid tubercle because it separates the carotid artery from the vertebral artery.

What is a capacious spinal canal? Answer Wiki. The spinal canal consists of a series of aligned arches formed by the pedicles and laminae of successive vertebrae, with the vertebral body forming the floor. Through this canal passes the spinal cord and its coverings, and the spinal nerve roots, which exit the canal between successive pedicles (the foraminae).

- Your cervical spine is made up of the seven bones, called cervical vertebrae, stacked on top of each other in your neck area. The cervical disks are the cushions that lie between the cervical vertebrae and act as shock absorbers to allow your neck to move freely.
