  5. Anatomy of the Spine. The regions of the spine all serve one main function: protecting the spinal cord. The spinal cord provides a communication pathway between our brain and sensations felt throughout the body in the bones, ligaments and nerves. When the spinal cord is damaged, neurological functioning is impaired
  6. The spinal cord is divided into 31 segments, each with a pair of anterior (motor) and dorsal (sensory) spinal nerve roots. On each side, the anterior and dorsal nerve roots combine to form the.
  7. There are numerous described variants of spinal nerve anatomy, but these are generally discovered during pre-operative testing or during surgery for an injury to the spine, spinal cord, or spinal nerve. A 2017 study evaluating the spinal nerve anatomy of 33 cadavers (deceased people) identified spinal nerve plexus variants in 27.3 percent of them

Spinal cord anatomy. The spinal cord is a soft bundle of nerves that extends from the base of the brain to the lower back. It runs through the spinal canal, which is protected by the bones of the spine (vertebrae). Messages between the brain and the nerve roots travel up and down the spinal cord Damage to the cervical spinal cord generally results in full or partial tetraplegia. C1 - C3: Injury to the C1, C2 and C3 sections of the spinal cord typically results in loss of function to the neck and below, including loss of diaphragm function which necessitates a ventilator for breathing

A drawing of a transverse section through the T10 spinal segment is shown on the right. The spinal cord is bilaterally symmetrical. Ventrally, the halves are separated by a ventral median fissure (into which pia mater invaginates). Dorsally, spinal halves are demarcated superficially by a dorsal median sulcus.Deep to the sulcus, a dorsal median septum (caudally a fissure) separates the halves Purchase Clinical Anatomy of the Spine, Spinal Cord, and ANS - 3rd Edition.
