Neuron Knowledge

Front

What are neurotransmitters?

Back

Chemical messengers that transmit signals across a synapse from one neuron to another.

Front

Where are neurotransmitters located?

Back

In the axon terminals of neurons.

Front

What is depolarization?

Back

A process where the membrane potential becomes less negative, moving towards zero.

Front

What is the normal resting potential of a neuron?

Back

-70mV.

Front

From which part of the neuron are neurotransmitters released?

Back

From the presynaptic neuron.

Front

What is the function of the cell body in a neuron?

Back

It contains the nucleus and organelles, and integrates signals from dendrites.

Front

What are dendrites?

Back

Branch-like structures that receive signals from other neurons.

Front

What is the role of the axon in a neuron?

Back

To transmit electrical impulses away from the cell body to other neurons or muscles.

Front

What is hyperpolarization?

Back

An increase in the membrane potential, making it more negative than the resting potential.

Front

What is a synapse?

Back

The junction between two neurons where neurotransmitters are released.
