In anatomy, the atlas (C1) is the most superior (first) cervical vertebra of the spine and is located in the neck.. The bone is named for Atlas of Greek mythology, just as Atlas bore the weight of the heavens, the first cervical vertebra supports the head. [1]
Our body's entire neural network sends any of this sensory information to the spinal cord to process. In order to stabilize spinal movement, there are many ligaments throughout the spine to hold the vertebrae and intervertebral discs together. These elements all working together allow for spinal movement and overall bodily stability and support ...
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 the vertebral artery, vertebral veins, and inferior cervical ganglion pass. The remainder of this article focuses upon ...
Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. [1] This procedure can be performed at any level in the spine (cervical, thoracic, lumbar, or sacral) and prevents any movement between the fused vertebrae.
The spinal nerves arise from the spinal column. The top section of the spine is the cervical section, which contains nerves that innervate muscles of the head, neck and thoracic cavity, as well as transmit sensory information to the CNS. The cervical spine section contains seven vertebrae, C-1 through C-7, and eight nerve pairs, C-1 through C-8.
Cervical vertebra. The pars interarticularis, or pars for short, is the part of a vertebra located between the inferior and superior articular processes of the facet joint. [1] [2] In the transverse plane, it lies between the lamina and pedicle. In other words, in the axial view, it is the bony mass between the facets that is anterior to the ...
In anatomy, the axis (from Latin axis, "axle") is the second cervical vertebra (C2) of the spine, immediately inferior to the atlas, upon which the head rests. The spinal cord passes through the axis. The defining feature of the axis is its strong bony protrusion known as the dens, which rises from the superior aspect of the bone.
In the cervical region, a small part of the body of vertebra inferior to the intervertebral disc also forms the anterior boundary of the IVF (due to the fact that the junction of the pedicle with the body of vertebra is situated somewhat more inferiorly on the body). [2]: 425
