Anatomy of the Spine

Anatomy of the Spine sp

The spine also called the backbone, is made up of vertebral bones with cushioning intervertebral discs between them. The spine is designed to give us stability and smooth movement, as well as providing a corridor of protection for the delicate spinal cord. It is supported by muscles, tendons, and ligaments, and innervated by nerves that branch out from the centrally placed spinal cord.

Lumbar Spine Anatomy

Lumbar Spine Anatomy sp

The spine also called the back bone, plays a vital role in stability, smooth movement and protection of the delicate spinal cord. It is made up of bony segments called vertebra with fibrous tissue called intervertebral discs between them. The vertebra and discs form the spinal column from the head to the pelvis, giving symmetry and support to the body.

Cervical Spine Anatomy

Cervical Spine Anatomy sp

The cervical spine is highly mobile compared to the thoracic or lumbar spine. In contrast to other parts of the spine, the cervical spine has transverse foramina in each vertebra through which the vertebral arteries supply blood to the brain.

Thoracic Spine Anatomy

The thoracic spine is the central part of the spine, also called the dorsal spine, which runs from the base of the neck to the bottom of your rib cage. The thoracic spine provides the flexibility that holds the body upright and protects the organs of the chest.
