The Nervous System (paper1)

Question 1

What’s a stimulus

Answer 1

Anything your body’s sensitive to

Question 2

What do sense organs contain

Answer 2

Receptor cells

Question 3

What do receptor cells detect

Answer 3

Stimuli

Question 4

What do receptor cells create

Answer 4

Impulses that are sent to the brain

Question 5

What does the brain do with impulses

Answer 5

Processes it then sends impulses to other parts of the body

Question 6

What do the impulses that the brain sends do

Answer 6

Cause some thing to happen(response)

Question 7

What also detects stimuli

Answer 7

Sensory neurones

Question 8

What’s the sensory neurone in your ear

Answer 8

Auditory nerve

Question 9

What’s the sensory neutron in your mouth

Answer 9

Taste receptors in taste buds

Question 10

What’s the sensory neutron in your nose

Answer 10

Olfactory receptor nerve

Question 11

What’s the travelling of the impulses called

Answer 11

Neurotransmission

Question 12

What’s the CNS

Answer 12

Central nervous system

Question 13

Where does the impulse first go

Answer 13

Dendrite

Question 14

Where does the impulse go after leaving the dendrite

Answer 14

The dendron and axon

Question 15

What passes the impulse to other neurones

Answer 15

Axon terminal

Question 16

What does the myelin sheath do

Answer 16

Electrically insulates the axon and dendron so the signal doesn’t lose energy

Question 17

What are motor neurons

Answer 17

Neurones that carry impulses to the effectors

Question 18

What do relay neurones do

Answer 18

Link motor and sensory neurones together in the spinal cord

Question 19

What happens when an impulse hits a synapse

Answer 19

A neurotransmission substance is released and picked up by the next neurone

Question 20

What are reflex actions

Answer 20

Actions that are immediate, automatic and protect the body

Question 21

How are the reflex arcs fast

Answer 21

They skip the processing part of the brain
