Anatomy Of The Spinal Cord

Spinal cord anatomy in the neck internal anatomy of the spinal cord. Like the brain the spinal cord is covered by three connective tissue envelopes called the meninges.

Cervical enlargement corresponds roughly to the brachial plexus nerves.

Anatomy of the spinal cord. Lumbar enlargement corresponds to the lumbosacral plexus nerves which innervate the lower limb. A component of the central nervous system it sends and receives information between the brain and the rest of the body. Cervical spinal cord injury.

Spinal nerves are grouped as cervical c1 c8 thoracic t1 t12 lumbar l1 l5. Spinal nerve cells called neurons carry messages to and from the spinal cord via spinal nerves. The spinal meninges help prevent the spinal cord.

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. Spinal cord neural pathways are found within the spinal cord white matter. The main job of the spinal cord is to be the communication system between the brain and the body by carrying messages that allow people to move and feel sensation.

The spinal cord is a cylindrical structure greyish white in colour. Spinal cord anatomy the spinal cord is a bundle of nerve fibers that extend from the brain stem down the spinal column to the lower back. Anatomy and physiology of the spinal cord.

When viewed as a cross section from above. Gray matter has a relatively dull color because it contains little myelin. It is composed of nerve fibres that mediate reflex actions and that transmit impulses to and from the brain.

Protective layers of the spinal cord. Cross sectional anatomy of spinal cord. There are two regions where the spinal cord enlarges.

It then travels inferiorly within the vertebral canal surrounded by the spinal meninges containing cerebrospinal fluid. Signs and symptoms of spinal cord compression. 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.

It passes through the spinal canal or spinal cavity of the vertebral column ie the backbone or spine. It has a relatively simple anatomical course. The spinal cord is part of the central nervous system cns.

The space between the outer and middle envelopes is filled with cerebrospinal fluid a clear. The spinal cord like the brain consists of two kinds of nervous tissue called gray and white matter. The spinal cord arises cranially as a continuation of the medulla oblongata part of the brainstem.

It is covered by the three membranes of the cns ie the dura mater arachnoid and the innermost pia mater. It contains the somas dendrites and proximal parts of the axons of neurons.
