• Vesicle

• Membrane

What are the chemical signalling molecules used to transfer signals between neurones called?

• Synapses

• Neurotransmitters

• Axons

• Neurones

Where are neurotransmitters released from?

• Vesicles

• Synapses

• Axons

What happens when neurotransmitters bind with receptors on the membrane of the second neurone?

• Chemical messengers are triggered

• Vesicles are released

• Synapse is formed

• Electrical impulse is generated

What is the main function of synapses?

• To generate electrical impulses

• To transfer signals between neurones

• To ensure impulses travel in both directions

• To confuse the nervous system

What is the correct pathway through the nervous system?

• Stimulus → Sensory neurone → Relay neurone → Motor neurone → Effector → Response

• Stimulus → Sensory neurone → Motor neurone → Relay neurone → Effector → Response

• Stimulus → Relay neurone → Sensory neurone → Motor neurone → Effector → Response

• Stimulus → Motor neurone → Relay neurone → Sensory neurone → Effector → Response

What type of response does a reflex response involve?

• Involuntary response

• Unconscious response

• Voluntary response

• Conscious response

How many main types of neurone are there in a reflex arc?

• 3

• 2

• 4

• 1

What is the role of a sensory neurone in a reflex arc?

• To generate an electrical impulse

• To transfer signals between neurones

• To coordinate the reaction

• To detect stimuli and send signals to the central nervous system

What is the role of a motor neurone in a reflex arc?

• To coordinate the reaction

• To transfer signals between neurones

• To generate an electrical impulse

• To carry signals from the central nervous system to the effector
