Cervical spinal nerves, also called cervical nerves, provide functional control and sensation to different parts of the body based on the spinal level where they branch out from the spinal cord. While innervation can vary from person to person, some common patterns include: C1, C2, and C3 (the first three cervical nerves) help control the head ...

Unlike other vertebrae, the atlas does not have a spinous process or a body. When seen from above, the atlas is really a ring shape that thickens laterally to produce the lateral masses, which are joined by anterior and posterior arches. The anterior archhas three features to note: 1. an anterior tubercleon the anterior surface 2. a facetfor the de...
The axis is more similar to the rest of the cervical spine vertebrae than the atlas but it does have an incredibly unique feature; the dens, or odontoid process. Often characterized as tooth-like or peg-like, this process is larger and longer than most other anatomical processes and extends from the body of C2. The dens and the spinal cord are enci...
C7 Is atypical for three reasons. The first is that the spinous process of C7 is the longest and can be easily palpated when the head is flexed forward as it is quite prominent in this position. In addition, the spinous process is not bifid. Finally, the foramen transversariumis quite small compared to the size of the transverse process and does no...

An understanding of this anatomy is essential for assessment and treatment of cervical spine problems. The cervical spine’s major functions include supporting and cushioning loads to the head/neck while allowing for rotation, and protecting the spinal cord extending from the brain. [1] The cervical spine is subjected to extrinsic factors such ...
Cervical spondylosis, also called arthritis of the neck, is the age-related slow degeneration of your disks and joints in your cervical spine. Cervical spinal cord injury. A cervical spinal cord injury is an injury to your cervical vertebrae. Most spinal cord injuries are the result of a sudden, traumatic blow to the vertebrae.
The cervical spine supports the weight of the head and enables head and neck movement.[1] [2] Intervertebral discs maintain the spaces between the vertebrae. These discs act like shock absorbers throughout the spinal column to cushion the bones as the body moves. Ligaments hold the vertebrae in place, and tendons attach the muscles to the spinal column. The cervical spine is ...
Sep 8, 2015 · The cervical spine is the most superior portion of the vertebral column, lying between the cranium and the thoracic vertebrae. It consists of seven distinct vertebrae, two of which are given unique names: The first cervical vertebrae (C1) is known as the atlas. The second cervical vertebrae (C2) is known as the axis.
