1

Fill in the blanks (only state the system/organ)

2

What are the 2 roles of the CNS?

  • Control of behaviour and psychological processes
  • Regulation physiological processes in the body to maintain life

3

What is the role of the brain?

Provides conscious awareness

4

What is the role of the spinal cord?

  • Transfer messages from brain to rest of body
  • Responsible for simple reflexes

5

What is the function of the cerebellum?

Responsible for controlling motor skills, balance coordination and muscles

6

What is the function of the occipital lobe?

Processes visual information

7

What is the function of the parietal lobe?

Integrates information from the different senses & important for spinal navigation

8

What is the function of the frontal lobe?

Associated with higher-order functions

e.g. planning, abstract reasoning, logic

9

What is the function of the temporal lobe?

Processes auditory information

10

What is the function of the brain stem?

Regulates automatic functions which are essential for life

e.g. Heartbeat, breathing, consciousness

11

What is the PNS made up of??

Made up of all nerves outside CNS

12

What is the role of PNS?

Relays nerve impulses back and forth between the body

13

What is the role of the somatic nervous system?

Transmits and receives information from senses & controls movement and reaction of muscles

14

What is the somatic nervous system made up of?

Made up of sensory receptors (that carry information to spinal cord and brain) & motor pathways (that allow brain to control movement)

 

15

What is the role of the autonomic nervous system?

Transmits information to and from internal organs to sustain life

[Involuntary actions (e.g. heart breaking, body temperature regulation) are regulated by ANS without conscious awareness]

16

What is the autonomic nervous system made up of?

Only motor pathways

17

What is the role of the sympathetic nervous system?

Involved in responses that prepare body for fight or flight

(increasing heart rate, blood pressure and lowering digestive activities)

18

What is the role of the parasympathetic nervous system?

Relaxes the body - returns us to 'normal' resting state

(lower heart rate, blood pressure and increased digestive activity)

19

Where are sensory neurons found?

Found in receptors e.g. eyes, ears. etc

20

What do sensory neurones do?

Carry nerve impulses to spinal cord and brain

(Don't always reach brain)

21

Where are relay neurones found?

Found in brain and spinal cord

22

What do relay neurones allow?

Allow sensory and motor neurones to communicate

23

Where are motor neurones found?

Found in CNS

24

What do motor neurones do?

  • Control muscle movements
    • When stimulated = release neurotransmitters which bind to receptor on muscles to trigger a response

25

What is the function of dendrites?

Receive signals from other neurones or from sensory receptor cells

26

What is the function of the cell body?

'Control Centre' - contains nucleus

27

What is the function of the axon?

(Long slender fibre that) carries nerve impulses as an electrical signal (AKA action potential) away from cell body to axon terminals (where neurone ends)

28

What is the function of the myelin sheath?

Insulates axon so electrical impulses travel faster along axon

29

What is the function of the axon terminal?

Connects neurone to other neurones using process called synaptic transmission

30

What is synaptic transmission?

Process where messages from one neurone are passed to another neurone despite the two not being physically connected
