Nerve Impulse Sequence

Front

What is a synapse?

Back

A synapse is the junction between two neurons where neurotransmitters are released to transmit signals.

Front

What charge does the inside of a resting neuron have?

Back

The inside of a resting neuron has a negative charge.

Front

What is the charge difference in a resting neuron?

Back

The inside of the neuron is negatively charged compared to the outside.

Front

What is the function of the myelin sheath?

Back

The myelin sheath is an insulating membrane that surrounds parts of the axon, helping to protect and propagate action potentials.

Front

Which factor does NOT affect the speed of action potential?

Back

The length of the axon does not affect the speed of action potential.

Front

What are neurotransmitters?

Back

Neurotransmitters are chemical messengers that transmit signals across a synapse from one neuron to another.

Front

What is an axon?

Back

An axon is a long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body.

Front

What role do dendrites play in a neuron?

Back

Dendrites are the branched projections of a neuron that receive signals from other neurons.

Front

What is action potential?

Back

Action potential is a rapid rise and fall in voltage or membrane potential across a cellular membrane.

Front

What is the role of the Node of Ranvier?

Back

The Node of Ranvier is a gap in the myelin sheath that facilitates the rapid conduction of action potentials.
