Although continuous with the brain the spinal cord begins where nervous tissue leaves the cranial cavity at the level of the foramen magnum.

Spinal canal anatomy. The anterior and posterior spinal arteries form anastomoses known as the vasocorona of the spinal cord and these supply nutrients to the canal. Spinal cord anatomy basically spinal cord is a long and narrow bundle of nervous tissues and support cells which extends from the base of our brain to the upper lumbar region. Under each pedicle a pair of spinal nerves exits the spinal cord and pass through the intervertebral foramen to branch out to your body.

The spinal cord is not uniform in diameter along its length. The spinal cord is a slender column of nervous tissue that passes downward from the brain into the vertebral canal. The hollow spinal canal contains the spinal cord fat ligaments and blood vessels.

It passes through the spinal canal or spinal cavity of the vertebral column ie the backbone or spine. This narrowing happens as a result of the degeneration of both the facet joints and the intervertebral discs. The nerves that branch off the spinal cord.

Spinal stenosis is a condition caused by a gradual narrowing of the spinal canal. Gross anatomy the spinal canal becomes progressively narrower from its superior opening at the foramen magnum to its. The facet joints also enlarge as they become arthritic which contributes to a decrease in the space available for the nerve roots.

When the vertebrae are set together within the vertebral column the entire series of vertebral foramina stacked one over another is called vertebral canal or spinal canal. Vertebral canal anatomy and contents. The epidural space contains loose fatty tissue and a network of large thin walled blood vessels called the internal vertebral venous plexuses.

This canal houses the spinal cord along with meninges and epidural space. The spinal cord is a tubular bundle of nervous tissue and supporting cells that extends from the brainstem to the lumbar vertebrae. Together the spinal cord and the brain form the central nervous system.

Vertebral canal or spinal canal is the long tubular space in the vertebral column formed by contiguous placement of vertebral foramen through which the spinal cord passes along with other contents vertebral foramens are stacked on one another to form a long canal. In this article we shall examine the macroscopic anatomy of the spinal cord its structure membranous coverings and blood supply. Cervical thoracic and lumbar spine anatomy overview the spinal canal is a ring of bones that houses and protects the spinal cord and spinal nerves.
