Spinal cord The spinal cord begins at the occipital bone and extends down to the space between the first and second lumbar vertebrae; it does not extend the entire length of the vertebral column. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. Also, the spinal cord has a varying width, ranging from 13 mm (1⁄2 in) thick in the cervical and lumbar regions to 6.4 mm (1⁄4 in) thick in the thoracic area.

Spinal nerve Spinal nerve, in vertebrates, any one of many paired peripheral nerves that arise from the spinal cord. In humans there are 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Each pair connects the spinal cord with a specific region of the body. Near the spinal cord each spinal nerve branches into two roots.

Spinal Cord Function and Anatomy The spinal cord is a cylindrical shaped bundle of nerve fibers that is connected to the brain at the brain stem. The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. The brain and spinal cord are the major components of the central nervous system (CNS).

Spinal Cord The spinal cord is a long, thin, tubular bundle of nerves that is an extension of the central nervous system from the brain and is enclosed in and protected by the bony vertebral column.The main function of the spinal cord is transmission of neural inputs between the periphery and the brain.he spinal cord is the main pathway for information connecting the brain and peripheral nervous system. The length of the spinal cord is much shorter than the length of the bony spinal column.

Spinal cord The spinal cord is continuous with the caudal portion of the medulla, running from the base of the skull to to the body of the first lumbar vertebra. It does not run the full length of the vertebral column in adults.lso, the spinal cord has a varying width, ranging from 13 mm (1⁄2 in) thick in the cervical and lumbar regions to 6.4 mm (1⁄4 in) thick in the thoracic area. The enclosing bony vertebral column protects the relatively shorter spinal cord.

What is spinal cord in medical terminology? The spinal cord is a long, thin, tubular bundle of nerves that is an extension of the central nervous system from the brain and is enclosed in and protected by the bony vertebral column (aka. the back bones). The main function of the spinal cord is transmission of neural inputs between the periphery (legs, arms, torso, etc) and the brain. In summary, the term spinal cord is correct medical/anatomical language. There is no better way of naming this structure of the body.

Tethered Spinal Cord A tethered spinal cord is a disorder in which a child's spinal cord is pulled down and stuck, or fixed, to the spinal canal.The spinal cord normally floats free inside the spinal canal. As a child grows, the spinal cord must be able to move freely inside the spinal canal. tethered spinal cord is a disorder in which a child's spinal cord is pulled down and stuck, or fixed, to the spinal canal.

Tethered Spinal Cord Syndrome Tethered Spinal Cord Syndrome. Tethered spinal cord syndrome is a neurological disorder caused by tissue attachments that limit the movement of the spinal cord within the spinal column. These attachments cause an abnormal stretching of the spinal cord. This syndrome is closely associated with spina bifida.

Medical Definition of Spinal cord Spinal cord: The major column of nerve tissue that is connected to the brain and lies within the vertebral canal and from which the spinal nerves emerge. Thirty-one pairs of spinal nerves originate in the spinal cord: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. The spinal cord and the brain constitute the central nervous system. The spinal cord consists of nerve fibers that transmit impulses to and from the brain. Like the brain, the spinal cord is covered by three connective-tissue envelopes called the meninges.
