ANATOMY

Detailed explanation-1: -This bundle is called the cauda equina because it resembles a horse’s tail. The cauda equina carries nerve impulses, both motor and sensory, to and from the legs. Like the brain, the spinal cord consists of gray and white matter.

Detailed explanation-2: -Neural pathways are groups of nerve fibers which carry information between the various parts of the CNS. Neural pathways that connect the CNS and spinal cord are called tracts. Ascending tracts run from the spinal cord to the brain while descending tracts run from the brain to the spinal cord.

Detailed explanation-3: -The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord. The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.

Detailed explanation-4: -The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.

Detailed explanation-5: -Your spinal cord has three main parts: Cervical (neck). Thoracic (chest). Lumbar (lower back).
