What are the 2 divisions of the efferent division of the peripheral nervous system?
Somatic system and the autonomic system.
Describe the movement of nerve impulses in the peripheral nervous system.
PNS receives impulses from the sensory organs via the afferent division and then relays signals or impulses from the CNS to muscles and glands via the motor or efferent division.
What are the 2 divisions of the peripheral nervous system?
Afferent, efferent
Collections of cell bodies inside the peripheral nervous system are called _____, and the collection of nerve axons in the peripheral nervous system are called _____.
ganglia, nerves.
What is included in the peripheral nervous system?
The PNS includes the cranial nerves and the spinal nerves.
Collections of cell bodies inside the central nervous system are called _____, and the collection of nerve axons in the central nervous system are called _____.
nuclei, tracts.
How are the parts of the central nervous system protected?
The skull protects the brain and the vertebrae protect the spinal cord.
List the 2 parts of the nervous system.
CNS and PNS (central nervous system and peripheral nervous system)
The function of the nervous system is to integrate and control the other body systems. Explain how the nervous system does this.
