Anatomy spinal cord. 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. Anatomy and physiology of the spinal cord. Spinal nerves are grouped as cervical c1 c8 thoracic t1 t12 lumbar l1 l5.

Signs and symptoms of spinal cord compression. Protective layers of the spinal cord. Spinal cord neural pathways are found within the spinal cord white matter.

The spinal meninges help prevent the spinal cord. It is covered by the three membranes of the cns ie the dura mater arachnoid and the innermost pia mater. Together the spinal cord and the brain form the central nervous system.

Both are covered by a protective membrane. Cervical spinal cord injury. The spinal cord is a cylindrical shaped bundle of nerve fibers that is connected to the brain at the brain stem.

Here are some basic anatomy facts. The spinal cord is not uniform in diameter along its length. It passes through the spinal canal or spinal cavity of the vertebral column ie the backbone or spine.

The brain is surrounded by the skull. 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 major nerve tract of vertebrates extending from the base of the brain through the canal of the spinal column.

The spinal cord is surrounded by rings of bone called vertebrae. The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. The spinal cord is part of the central nervous system cns.

There are two regions where the spinal cord enlarges. In this article we shall examine the macroscopic anatomy of the spinal cord its structure membranous coverings and blood supply. The spinal cord is a tubular bundle of nervous tissue and supporting cells that extends from the brainstem to the lumbar vertebrae.

Lumbar enlargement corresponds to the lumbosacral plexus nerves which innervate the lower limb. The spinal cord is a slender column of nervous tissue that passes downward from the brain into the vertebral canal. Spinal cord anatomy in the neck internal anatomy of the spinal cord.

When viewed as a cross section from above. Although continuous with the brain the spinal cord begins where nervous tissue leaves the cranial cavity at the level of the foramen magnum. It is composed of nerve fibres that mediate reflex actions and that transmit impulses to and from the brain.
