Anatomy of spine

The human spine is made up of five sections consisting of 33 bony vertebrae. The seven cervical vertebrae make up the neck, the twelve thoracic vertebrae that comprise the chest and have ribs attached and the five lumbar vertebrae make up the low back between the chest and pelvis. The five sacral vertebrae are fused and is caged within the bones of the pelvis and the coccyx is the lowest segment of the spine. The spine has a normal cervical and lumbar lordosis and a thoracic kyphosis.

The spinal canal contains the spinal cord and nerves. There are 31 pairs of spinal nerves.The spinal nerves exit the spinal canal through the neural foramens to supply right and left side of the body.

The spine acts to hold the body upright, permit movement and protect the spinal cord and nerves.  In general, each vertebra consists of an anterior vertebral body and a posterior neural arch. Each vertebra articulates with the adjacent one through the anterior intervertebral disc and the two posterior facet joints.

There are 23 Intervertebral discs in the spine . Each intervertebral disc is composed of a central gelatinous material (the nucleus pulposus) and an outer fibrous ring (the annulus fibrosus). The intervertebral discs function as shock absorbers that permit cushioning and movement between the bones of the spine. The facet joints are synovial joints.

The pedicles and laminae forms the posterior neural arch, through which the spinal cord and nerves pass in the spinal canal. The transverse and spinous processes project from the neural arch and gives attachment to muscles and ligaments.The facet joints are synovial joints.The spinal canal contains the spinal cord and nerves. There are 31 pairs of spinal nerves.The spinal nerves exit the spinal canal through the neural foramens to supply right and left side of the body.
