Spinal Cord Anatomy

Gross anatomy the spinal cord measures approximately 42 45 cm in length 1 cm in diameter and 35 g in weight. The white matter is grouped into discrete sectors called funiculi.

Spinal Cord Syndrome

It is covered by the three membranes of the cns ie the dura mater arachnoid and the innermost pia mater.

Spinal cord anatomy. Together the vertebrae and the membrane make up the spinal column or backbone. An interactive quiz covering spinal cord cross sectional anatomy through multiple choice questions and featuring the iconic gbs illustrations. The spinal cord is surrounded by rings of bone called vertebrae.

The white matter consists of myelinated fibres or axons that form nerve tracts ascending to and descending from the brain. Spinal cord anatomy protective structures of the spinal cord the nervous tissue of the central nervous system cns is very delicate and does not respond well to injury or damage. The spinal cord is part of the central nervous system cns which extends caudally and is protected by the bony structures of the vertebral column.

The gray matter contains cell bodies unmyelinated motor neuron fibres and interneurons connecting the two sides of the cord. There are two regions where the spinal cord enlarges. It passes through the spinal canal or spinal cavity of the vertebral column ie the backbone or spine.

The spinal cord is protected by the bones of the spinal cord and enclosed in the protective tissue of the meninges mater. Lumbar enlargement corresponds to the lumbosacral plexus nerves which innervate the lower limb. Cervical spinal cord injury.

Both are covered by a protective membrane. The brain is surrounded by the skull. When viewed as a cross section from above.

Anatomy and physiology of the spinal cord. Cervical enlargement corresponds roughly to the brachial plexus nerves. Protective layers of the spinal cord.

The cord is an ovoid shaped column of nerve tissue that extends from the medulla at the underside of the brain down through cavities in the spinal column to the second lumbar vertebrae. The spinal meninges help prevent the spinal cord. Like the brain it is composed of grey and white matter however opposite to the brain the grey matter is on the internal aspect of the cord and the white matter tracts are external.

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.
