Answer section This will take you through the same questions again, showing you the answers with some explanation. Click here to start answer section

Typically a muscle effector The effector has to produce the required response – eg your arm muscle must lift your hand away from a hot surface. (The effector can also be a gland which releases a hormone) 24

Carries the impulse away from the receptor sensory neurone This is linked to the receptor and carries an electrical signal ( the message) away from the receptor towards the spinal cord. 25

Releases a chemical synapse A synapse is the gap between the end of one neurone and the beginning of the next one. The signal is passed across this gap as a chemical. 26

The neurone in the spinal cord relay neurone The relay neurone hands on the message from the sensory neurone to the motor neurone, just like a baton is passed on in a relay race. 27

Produces the response effector This is a definition of effector – it can be a muscle or a gland which releases a hormone 28

Responds to the stimulus receptor This is a definition of receptor. It is often a sense cell 29

Eg a cell in the retina of the eye receptor This is an example of a receptor. Others might be the pain- and temperature-sensitive cells in your skin 30

Carries impulse away from the spinal cord motor neurone If the impulse if going away from the spinal cord, it must be going to an effector eg a muscle. The muscle will get a message to move – hence the term “motor neurone” 31

First neurone to carry an impulse in a reflex arc sensory neurone There are three neurones in a reflex arc : sensory neurone, then relay neurone and finally motor neurone 32

Found at each end of a relay neurone synapse Synapse is the name for the gap between neurones. The electrical signal triggers the release of a chemical which travels across the synapse 33
