Explanation:
- 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, these tracts are responsible for carrying sensory and motor stimuli to and from the periphery (respectively)
- The ascending tracts transmit sensory information from the sensory receptors to higher levels of the CNS
- The descending tracts originate from different cortical areas and from brain stem nuclei
- The descending pathway carry information associated with maintenance of motor activities such as posture, balance, muscle tone, and visceral and somatic reflex activity
Yes, yes it does for that statement.
