Neuron Synapse

Front

What is the process called when excess neurotransmitters in the synapse are taken back into the presynaptic neuron?

Back

Reuptake

Front

What type of neuron is represented by the blue nerve in the image?

Back

Motor neurone

Front

What is the part of the neuron that receives signals from other neurons?

Back

Dendrite

Front

How do neurotransmitters cross the synaptic cleft?

Back

Simple diffusion

Front

What happens when the action potential arrives at the axon terminal?

Back

It depolarizes the pre-synaptic membrane.

Front

What is the role of neurotransmitters in the synapse?

Back

They transmit signals between neurons.

Front

What is the synaptic cleft?

Back

The small gap between the presynaptic and postsynaptic neurons.

Front

What is the function of the axon terminal?

Back

To release neurotransmitters into the synaptic cleft.

Front

What is depolarization in the context of neurons?

Back

A change in membrane potential that makes it more positive.

Front

What is the difference between sensory, motor, and relay neurons?

Back

Sensory neurons carry signals to the CNS, motor neurons carry signals away from the CNS, and relay neurons connect sensory and motor neurons.
