Where does the efferent pathways of the parasympathetic division originate from as they leave the cns?
They originate from the cranial and sacral regions of the CNS
Where do all of the structures in the cns originate from?
Neural Tube
What division transmits impulses from the cns to the muscles or glands?
The sensory or afferent division of the peripheral nervous system transmits impulses from the sense organs to the CNS.
What outflow of the sympathetic division occurs from which regions of the CNS?
Thoracolumbar
Carries impulses between the periphery and CNS areas?

What are the two cell populations in the body that do not undergo cell division?

How does the rabies virus move from the PNS to the CNS?
Rabies virus travel physically along the nerves by division of virus.
Which nervous system division are neurolemmocytes located?
Shwann Cells-PNS Oligodendrocytes-CNS Both form the neurolemma
Which fiber tract carries impulses from the cerebrum to lower CNS areas?
The corticospinal tract carries impulses from the cerebrum to lower CNS areas, primarily to control voluntary movements throughout the body. It is involved in motor function and helps in coordinating muscle movements.
What are the two main division of the nervous system?
The two main divisions of the nervous system are the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which consists of the nerves that extend from the CNS to the rest of the body.
To what major division of the nervous system does the spinal cord belong?
peripheral nervous system, or PNS, consists of the nerves outside the cns.
