Descending tracts are the pathways by which motor signals are sent from the brain to the spinal cord. They are also called motor tracts, due to their involvement in movement coordination. These tracts can be classified by their structural arrangement, into lateral and medial tracts. Or they can...
The spinal cord is part of the central nervous system and coordinates motor, sensory, and reflex signals. Anatomically, the spinal cord is located within the spinal canal and extends from the botto...
Descending tracts carry motor signals from the brain to spinal cord. However, few previous studies show the full view of the long tracts from a 3D perspective. In this study, we have followed five less well-known tracts that project from midbrain, hindbrain, and cerebellum to the mouse ...

Most of the white matter consists of the ascending and descending tracts. The white matter on each side is divided into three funiculi, which are white columns named by their positions. There are dorsal, lateral, and ventral funiculi. Each contains several fiber tracts. Each trace consists of ...
The white matter is composed of myelinated and unmyelinated nerve fibers that represent ascending, descending and transverse pathways Gray Matter and Spinal Roots The gray matter consists of mirror-image lateral gray masses connected by a cross-bar of gray matter called the gray commissure that encl...

The meaning of SPINAL CORD is the cord of nervous tissue that extends from the brain lengthwise along the back in the spinal canal, gives off the pairs of spinal nerves, carries impulses to and from the brain, and serves as a center for initiating and co

To detect deterioration of spinal cord function and to prevent permanent damage by reversing the surgical maneuver, a number of intraoperative monitoring methods have been developed. Presently available methods, however, measure only the sensory pathways. Recently, there have been a number of clinical ...
