Question 3

Describe the divisions of the nervous system.

Answer 3

Possible content:
* the nervous system is divided into the central and peripheral nervous systems
* the CNS comprises the brain and spinal cord
* the peripheral nervous system is further divided into the somatic nervous system and the autonomic
nervous system (ANS)
* the somatic nervous system consists of sensory and motor neurons to carry sensory and motor
information to and from the CNS and also enables reflex actions
* the ANS acts largely unconsciously/involuntary
* the ANS is divided into the sympathetic nervous system (SNS) and the parasympathetic nervous
system (PNS)
* the SNS prepares us for flight or fight
* the PNS balances the sympathetic nervous system providing ‘rest and digest’ functions.
