The spinal cord has numerous groups of nerve fibers going towards and coming from the brain. These have been collectively called the ascending and descending tracts of the spinal cord, respectively. The tracts are responsible for carrying sensory and motor stimuli to and from the periphery (respectively).Click to see full answer. Herein, what are the ascending tracts of the spinal cord?The ascending tracts refer to the neural pathways by which sensory information from the peripheral nerves is transmitted to the cerebral cortex. In some texts, ascending tracts are also known as somatosensory pathways or systems.Furthermore, where are ascending and descending tracts located? Ascending tracts are found in all columns whereas descending tracts are found only in the lateral and the anterior columns. The spinal cord white matter and its three columns, and the topographical location of the main ascending spinal cord tracts. Also Know, what is the difference between ascending tracts and descending tracts of the spinal cord? Ascending & Descending tracts of spinal cord. The only difference is the different locations where each order of neuron ends. Decussation is the cross-over of the tract from one side to the other. Therefore, there are instances where the left side of the body is controlled by the right brain hemisphere.Which portion of the spinal cord is called the ascending tract?The fasciculus gracilis is found throughout the spinal cord and begins at the caudal end of the spinal cord. It comprises long ascending fibers from different spinal nerves which enter the spinal cord through the ipsilateral dorsal spinal root, including sacral, lumbar and lower six thoracic nerves.
