It contains and protects the spinal cord. The axis, also known as the epistropheus, is the second cervical vertebra (C2) that has some similarities to a typical cervical vertebra but is categorized as an atypical vertebra because of its unique features. In adults, the five sacral vertebrae fuse to form a single bone, the sacrum, and the four rudimentary coccygeal vertebrae fuse to form the coccyx. During the surgery, vertebrae are fused together to heal into a single solid bone, eliminating movement between them and relieving pain. Early symptoms of ankylosing spondylitis might include back pain and stiffness in the lower back and hips, especially in the morning and after periods of inactivity. Spinal fusion, also called spondylodesis or spondylosyndesis, is a neurosurgical or orthopedic surgical technique that joins two or more vertebrae. The spinal cord in this region has protection from five durable and mobile vertebrae (L1-L5) that allow for the dispersion of axial forces. It consists of five vertebrae known as L1 - L5. The C4 vertebra is located in the neck region of the spinal column, just above the thoracic vertebrae. It protects vital organs, provides framework, and supports soft parts of the body.

The cylindrical body of the vertebra is a stacking agent; in other words, the spinal column is made up of the 24 vertebrae, which are stacked one on top of the other. Each intervertebral joint is a complex of three separate joints; an intervertebral disc joint (intervertebral symphysis) and two zygapophyseal (facet) joints. L1: This vertebra begins the lumbar spine after the thoracic spine ends. This joint allows the head to nod up and down. The bones are stacked on top of each other and securely attached with a disc in between each one. The L2 vertebra is the second uppermost of the five (5) lumbar vertebrae toward the lower end of the spinal column, within the lower back.

The second vertebral body is called the axis and acts like a post that supports the atlas. The lumbosacral joint is the site of most movements of the lumbar spine. In rare cases when 3 months of treatments have not reduced the pain, or if a spinal instability threatens the spinal cord or a nerve root, surgery may be indicated. After that point, nerve roots exit each of the remaining. An intervertebral disc (or intervertebral fibrocartilage) lies between adjacent vertebrae in the vertebral column. The region between the spinous process and the transverse process is called the lamina. The number of vertebrae varies from 39 to 63, with remarkable variation within the neck series. It consists of 3 major subgroups: semispinalis, multifidus and rotatores. ] Any of the 33 bony segments of the spinal column: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal vertebrae.
