Q
Nervous system

- Consists of CNS and PNS
2
Q
Functions of the nervous system
A
- Collect, process and response to environmental stimuli
- Co-ordinate working of different organs and cells
3
Q
Central nervous system (CNS)
A
- Consists of brain and spinal cord
4
Q
Role of brain in CNS
A
- Centre for higher cognitive function/all conscious awareness
5
Q
Role of spinal cord in CNS
A
- Passes messages (impulses) to and from brain
- Connects CNS nerves to PNS
- Reflex actions
6
Q
Peripheral nervous system (PNS)
A
- Nervous system existing outside of CNS
- Sends information to CNS from outside world and transmits impulses from CNS to muscles and glands
7
Q
PNS subdivisions
A
- Autonomic nervous system (ANS)
- Somatic nervous system (SNS)
8
Q
Autonomic nervous system (ANS)
A
- Involuntary system that transmits information to and from bodily organs
- Divided into sympathetic and parasympathetic nervous systems
9
Q
Sympathetic nervous system
A
10
Q
Parasympathetic nervous system
A
11
Q
Somatic nervous system
A
- Transmits information from receptor cells to CNS
- Receives information from CNS to direct muscles
- Directs voluntary movements

Endocrine system
A
(Major information) system that instructs glands to release hormones into bloodstream where they are carried around the body, reaching the target organ
