Parts of a Neuron

Front

What is the function of the Axon Terminal in a neuron?

Back

The Axon Terminal is responsible for transmitting signals to other neurons by releasing neurotransmitters.

Front

What is a neurotransmitter?

Back

A neurotransmitter is a chemical produced by neurons that carries messages to other neurons.

Front

What is Action Potential?

Back

Action Potential is the electrical charge that travels down an axon when a neuron is firing.

Front

What is the Soma (Cell Body) of a neuron?

Back

The Soma, or Cell Body, contains the nucleus and is responsible for maintaining the life of the neuron.

Front

What is the direction of neural impulse within a neuron?

Back

The correct direction of the neural impulse is from Dendrite to Axon Terminal.

Front

What role do Dendrites play in a neuron?

Back

Dendrites receive signals from other neurons and transmit them to the Cell Body.

Front

What is the Myelin Sheath?

Back

The Myelin Sheath is a fatty layer that insulates the axon and speeds up the transmission of electrical impulses.

Front

What is a Synapse?

Back

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

Front

What is Resting Potential?

Back

Resting Potential is the state of a neuron when it is not firing, characterized by a negative charge inside the cell.

Front

What is the Refractory Period?

Back

The Refractory Period is the time after an Action Potential during which a neuron cannot fire again.
