What is the tiny gap between neurons where nerve impulses are sent from one neuron to another?

Back

Synapse

Front

From which part of the neuron are neurotransmitters released?

Back

Presynaptic neuron

Front

What type of neurotransmitters must a neuron receive to have an action potential?

Back

Excitatory neurotransmitters

Front

What is the state of a neuron when it is not engaged in an impulse?

Back

Resting potential

Front

What is a chemical produced by neurons that carries messages to other neurons?

Back

Neurotransmitter

Front

What is the function of the axon in a neuron?

Back

To transmit electrical impulses away from the cell body.

Front

What is the role of dendrites in a neuron?

Back

To receive signals from other neurons.

Front

What is the myelin sheath?

Back

A fatty layer that insulates axons and speeds up nerve impulse transmission.

Front

What happens during an action potential?

Back

The neuron's membrane potential becomes more positive, leading to the transmission of an impulse.

Front

What is the difference between excitatory and inhibitory neurotransmitters?

Back

Excitatory neurotransmitters increase the likelihood of an action potential, while inhibitory neurotransmitters decrease it.
