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 ...
On plain radiography, prevertebral space should be less than 6 mm at C3 vertebral level in children; while in adults, the space should be less than 6 mm at C2 level and less than 22 mm at C6 level. Causes of enlarged prevertebral space could be edema, hematoma, abscess, tumors, and post surgical changes. [5]
The danger space or alar space, is a region of the neck. [1] The common name originates from the risk that an infection in this space can spread directly to the thorax , and, due to being a space continuous on the left and right, can furthermore allow infection to spread easily to either side.
A typical vertebra has a body (vertebral body), also known as the centrumwhich consists of a large anterior middle portion, and a posterior vertebral arch, [2] also called a neural arch. [3] The body is composed of cancellous bone , which is the spongy type of osseous tissue , whose microanatomy has been specifically studied within the pedicle ...
In a typical vertebra, the vertebral foramen is the foramen (opening) of a vertebra bounded ventrally/anteriorly by the body of the vertebra, and the dorsally/posteriorly by the vertebral arch. [ 1 ] : 421
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.
Spinal stenosis is a narrowing of the canal which can occur in any region of the spine and can be caused by a number of factors. It may result in cervical myelopathy [4] if the narrowed canal impinges on the spinal cord itself. Spinal canal endoscopy can be used to investigate the epidural space, and is an important spinal diagnostic technique ...
The atlas is the topmost vertebra and the axis (the vertebra below it) forms the joint connecting the skull and spine. The atlas and axis are specialized to allow a greater range of motion than normal vertebrae. They are responsible for the nodding and rotation movements of the head.
