Spinal cord, major nerve tract of vertebrates, extending from the base of the brain through the canal of the spinal column. It is composed of nerve fibres that mediate reflex actions and that transmit impulses to and from the brain. The spinal cord and t
The spinal cord, located inside the vertebral canal, transmits nerve impulses to 31 pairs of spinal nerves, allowing communication between the brain and peripheral nerves. Of clinical relevance, this transmission is achieved through two basic functions: afferent signals, in which sensations that arise...
The spinal cord also performs important processing functions to maintain balance and respond quickly to stimuli. Anatomy The spinal cord is a mass of nervous tissue that extends inferiorly from the brain stem through the vertebral canal of the cervical and thoracic regions, ending around the T12 ...

The spinal cord is a long, tube-like structure extending from the base of your brain (the brain stem). It’s made of a collection of nerves and is encircled and protected by the bones of the spine (vertebrae). Spinal Cord Anatomy ...
The spinal cord has a small diameter, it lies within a rigid bony canal and it contains important neural elements. Therefore, relatively small lesions within the parenchyma or in the extraaxial space often present with serious neurologic deficits. For these reasons, imaging of the spine and ...
This entry describes the gross anatomy of the spinal cord, including its blood supply, and its internal structure. The various descending motor pathways (corticospinal, rubrospinal, tectospinal, vestibulospinal and reticulospinal) and the ascending somatosensory pathways (anterolateral system (ALS), ...
