Nervous system- conscious responses

What is the function of the nervous system?

• Helps us to react to our surroundings and coordinates our behaviour

• Helps us to know when we are hungry

• Helps us to release hormones into our blood

Which of these is a reflex action?

• picking up a pen

• eating a sandwich

• blinking

• kicking a football

Does a reflex action use your brain?

• Yes

• No

Which is the correct order for a conscious response?

• sensory neuron, stimulus, motor neuron, receptor, effector, response, brain

• sensory neuron, brain, motor neuron, effector, response, stimulus, receptor

• stimulus, receptor, motor neuron, brain, sensory neuron, effector, response

• stimulus, receptor, sensory neuron, brain, motor neuron, effector, response

What does the sensory neuron initiate (start)?

• a message

• an electrical impulse

• a reflex action
