What is a nerve pathway?

Neuronal or nerve pathways are collections of nerve fibers that transmit data throughout the CNS. The CNS and spinal cord's neural tracts are referred to as tracts.

While descending tracts travel from the brain to the spinal cord, ascending tracts do the opposite. They are in charge of sending and receiving peripheral sensory and motor information.

For instance, this is how your brain receives information from your fingertips and how conscious and reflexive actions are transmitted back to your fingers.

Three types of neural pathways can be distinguished.

  1. Ascending pathways
  2. Descending pathways
  3. Intracerebral connections
