Flashcards in Biopsychology 1: Deck (24):
1

Cns consists of:

brains and spinal cord

2

CNS recieves info how?

From the senses and controls the body's responses

3

Peripheral nervous system is located...

outside of the spinal cord

4

peripheral nervous system consists of:

nerve cells leading to and from the CNS connects the CNS to the outside world.

5

somatic nervous system carries :

sensory and motor information to and from the CNS controls the voluntary movements

6

The autonomic nervous system governs

involuntary activity of internal systems e.g. heartrate

7

The autonomic nervous system is in control of

the parasympathic nervous system and teh sympathetic nervous system

8

The PNS controls:

Fight or flight

9

The SNS controls

Rest and digest

10

The CNS has two main functions whcih are:

regulation of behaviour, regulation of body physiological processes

11

Role of teh occipital lobe ?

process visual info

12

frontal lobe's role?

involved in thouhgt adn speech production and learning

13

Role of parietal lobe?

processes sensory information such as touch, temp and pain

14

Role of temporal lobe?

hearing and memory

15

What occurs when teh ANS causes arousal and energy?

Increased heart rate, reduced stomach activity, pupils dilate, expends energy 'flight or fight response'

16

What occurs when teh ANS causes reductionn in arousal?

Decreased heart rate, conserves energy , increased stomah activity, 'rest and digest'

17

What are neurons?

cells which make up the nervous system, they conduct an electical impulse

18

What are dendrites

receives signals from other neurons or sensory receptors

19

what are cell bodies

controls the centre of teh neuron

20

What is an axon?

conducts nerve impulses away from the cell body towards other neurons

21

Role of motor neurons ?1

to carry motor comands from CNS to the skeletal muscles or glands aloowing for a control of movement and responses of internal systems.

22

where are motor neurons located/

in the CNS they projext axons out to directly or indirectly control muscles

23

What are relay neurons?

Within the CNS That connect different parts of the CNS amd allow for sensory and motor neurons to communicate with eachother

24

function of a relay neuron?

to carry signals between afferant (sensory) and efferent (motor) neurons
