Question 1

What is the job of the synapse

Answer 1

Connect neurones

Question 2

How is the nerve signal transferred

Answer 2

By chemicals which diffuse (move) across the gap

Question 3

What do the chemicals do in a synapse once they’ve diffused across the two neurones

Answer 3

Set off a new electrical signal in the next neurone

Question 4

Answer 4

Question 5

Reflexes are….

Automatic responses to certain stimuli - they can reduce the chance of becoming injured

Question 6

For example if someone shines light in your eye…..

Answer 8

A reflex arc

Question 9

Where does the reflex arc go through

Answer 9

The central nervous system

Question 10

What is the order of the reflex arc

Answer 10

Stimulus

Relay neurone
Motor neurone
Effector
Response
