Anatomy Of Spinal Cord

The spinal cord is composed of neurons that send and receive signals along tracts towards and away from the brain. It is covered by the three membranes of the cns ie the dura mater arachnoid and the innermost pia mater.

Spinal cord neural pathways are found within the spinal cord white matter.

Anatomy of spinal cord. Spinal cord major nerve tract of vertebrates extending from the base of the brain through the canal of the spinal column. Anatomy and physiology of the spinal cord. The spinal meninges help prevent the spinal cord.

Spinal nerves are grouped as cervical c1 c8 thoracic t1 t12 lumbar l1 l5. It then travels inferiorly within the vertebral canal surrounded by the spinal meninges containing cerebrospinal fluid. There are two regions where the spinal cord enlarges.

Signs and symptoms of spinal cord compression. Spinal cord anatomy in the neck internal anatomy of the spinal cord. A component of the central nervous system it sends and receives information between the brain and the rest of the body.

The spinal cord is a cylindrical structure greyish white in colour. 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. Lumbar enlargement corresponds to the lumbosacral plexus nerves which innervate the lower limb.

It passes through the spinal canal or spinal cavity of the vertebral column ie the backbone or spine. The spinal cord is a bundle of nerve fibers that extend from the brain stem down the spinal column to the lower back. Protective layers of the spinal cord.

The spinal cord like the brain consists of two kinds of nervous tissue called gray and white matter. Cross sectional anatomy of spinal cord. The spinal cord arises cranially as a continuation of the medulla oblongata part of the brainstem.

It has a relatively simple anatomical course. Cervical spinal cord injury. The spinal cord is part of the central nervous system cns.

It is composed of nerve fibres that mediate reflex actions and that transmit impulses to and from the brain. Cervical enlargement corresponds roughly to the brachial plexus nerves. It contains the somas dendrites and proximal parts of the axons of neurons.

When viewed as a cross section from above. 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. Gray matter has a relatively dull color because it contains little myelin.
