Study Notes
- The nervous system is made up of neurons and neuroglia.
- It is divided into two main subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
- The CNS consists of the brain and spinal cord.
- The PNS includes all nervous tissue outside the CNS.
- Components of the PNS include nerves, ganglia, enteric plexuses, and sensory receptors.
- Twelve pairs of cranial nerves and thirty-one pairs of spinal nerves make up the PNS.
- Ganglia are small masses of nervous tissue located outside the CNS.
- Enteric plexuses are extensive networks of neurons located in the walls of organs of the gastrointestinal tract.
- The PNS is divided into the somatic nervous system (SNS), autonomic nervous system (ANS), and enteric nervous system (ENS).
- The SNS consists of sensory neurons and motor neurons that conduct impulses from the CNS to skeletal muscles only.
