The Nervous System

Question 1

What does biopsychology use to explain behaviour?

Answer 1

Uses biology to explain behaviour

Question 2

What does the nervous system allow you to do?

Answer 2

Respond to changes in your environment

Question 3

What do receptors do?

Answer 3

Detect stimuli

Question 4

WhAt do effectors do?

Answer 4

Bring about response to a stimulus

Question 5

How do receptors communicate with effectors?

Answer 5

Via the nervous system or endocrine system

Question 6

What is the nervous system split into?

Answer 6

Central nervous system and the peripherial nervous system

Question 7

What is the CNS made up of?

Answer 7

Made up of brain and spinal chord

Question 8

What is the pns made up of?

Answer 8

The neurons that connect the CNS to the rest of the body

Question 9

What is the pheripheral nervous system split into?

Answer 9

The autonomic nervous system and the somatic nervous system

Question 10

What does the autonomic nervous system do?

Answer 10

Controls unconscious activities e.g digestion

Question 11

What does the somatic nervous system do?

Answer 11

Controls conscious activities such as walking

Question 12

What is the autonomic nervous system split unto?

Answer 12

The sympathetic nervous system and the parasympathetic nervous system

Question 13

What does the sympathetic nervous system do?

Answer 13

Gets the body ready for action. Fight or flight

Question 14

What does the parasympathetic do?

Answer 14

Calms the body. It is the rest and digest system

Question 15

What are the cells of the nervous system called?

Answer 15

Neurons

Question 16

What do neurons transmit information as?

Answer 16

Electrical impulses around the body

Question 17

How are electrical impulses sent around the body?

Answer 17

1. cell body has dendrites that receive info from other neurons
2. Info passes along axon that ends up at synaptic knob.
3. there is a small gap before the next neuron called a synapse
4. Neurotransmitters are chemicals that are released form the synaptic knob

Question 18

What are sensory neurons?

Answer 18

Nerve cells that transmit electrical impulses from receptors to CNS

Question 19

What is the relay neuron?

Answer 19

Nerve cells that transmit electrical impulses between sensory and Mortor neurons

Question 20

What are motor neurons?

Answer 20

Nerve cells that transmit electrical impulses from CNS to effectors

Question 21

What do reflexes prevent?

Answer 21

Injury

Question 22

What is the transmission of information to and from the CNS

Answer 22

Stimulus 
Receptors 
CNS
Effectors 
Stimulus

Question 23

What are reflexes?

Answer 23

Reflexes are fast automatic responses to certain stimuli

Question 24

Nervous system diagram

Answer 24

Nervous system

CNS. PNS

                      ANS.        SNS

         SNS.               PSNS

Question 25

What can nuerotransmitters be?

Answer 25

Excitatory or inhibitory

Question 26

What are excitatory nuerotransmitters?

Answer 26

Increase the likelihood that an electrical impulse will be triggered in the post synaptic neuron

Question 27

What are inhibitory neurotransmitters?

Answer 27

Decrease the likelihood that an electrical impulse will be triggered in the post synaptic neuron
