Neuron communication

Question 1

Name the 3 types of neurons

Answer 1

Sensory neuron

Motor neuron

Interneuron

Question 2

What is the function of the sensory neuron

Answer 2

Carry sensory info about a change in the external or internal environment and from sense organs to the spinal cord and brain (CNS)

E.g. Touch a hot stove - the sensory neurons in your fingertips would tell your CNS that what you touched was hot

Question 3

What is the function of the motor neuron

Answer 3

Also known as efferent neurons

Carry signals from the interneuron in the CNS to the effector ( muscles and glands ) and causes it to respond

Question 4

What is the function of the interneuron

Answer 4

Located ONLY in the CNS

Processes impulses in the brain and spinal cord sent by the sensory neuron to a motor neuron

Question 5

What happens when information reaches the axon terminal?

Answer 5

The information is then sent out to an adjacent neuron.

This relay of information happens through neurotransmitters at the synapse (a gap between two neurons)

Question 6

How is the adjacent neuron able to receive this information?

Answer 6

Because the receptors on the membrane of the dendrites are able to bind to the neurotransmitter sent out by the other neuron.
