What is the benefit of a nerve plexus?
Damage to one single branch of a plexus does not necessarily disrupt all motor information sent to a region.
The function of the Nervous System can be broken down into which three categories?
sensory functions, or detection of sensations within and outside the body; integrative functions, or “decisionmaking” processes; and motor functions.
