Ascending tracts: Carry sensory information up the cord to the brain Pathway consists of 3 types of neurons : 1st-order neurons : detect the stimulus and transmit it to the spinal cord 2nd-order neurons : carry the signal up the spinal cord to the brain stem 3rd-order neurons : carry...
Spinal cord neural pathways are found within the spinal cord white matter. On each side, the white matter is divided into three funiculi: anterior, lateral, and posterior. Ascending tracts convey information from the periphery to the brain. On the other hand, the descending tracts carry informati...

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...
“first-order neurons” because they are the first neuron in a sequence of three: sensory neurons enter the gray matter of the spinal cord, where they synapse. Then the impulse goes on to enter the white matter, ascending into the ventral posterolateral nucleus of the thalamus, and finally,...

Pyramidal tracts –originate in the motor cortex; carry motor fibers to the spinal cord and brainstem. They are responsible for the voluntary control of the striated muscles of the body and face. Extrapyramidal tracts –originate in the brain stem; carry motor fibers to the spinal cord. They ...

as well as in serious circumstances it could trigger paralysis of limbs, loss the urinary bladder control, fecal incontinence, sexual inability, and the interruption in the descending and ascending fiber tracts of the spinal cord (Olby, 2010; Sahni and Kessler, 2010; Assunção-Silva et al....
