What produces myelin?

Back

Schwann Cells

Front

What structure conducts action potentials away from the cell body?

Back

Axon

Front

What are dendrites?

Back

Dendrites are the structures that receive signals from other neurons.

Front

What is the cell body of a neuron?

Back

The cell body contains the nucleus and organelles, and it integrates signals.

Front

What are Nodes of Ranvier?

Back

Nodes of Ranvier are gaps in the myelin sheath that facilitate rapid signal transmission.

Front

What is an action potential?

Back

An action potential is a rapid change in voltage across a neuron's membrane that allows for signal transmission.

Front

Can an action potential occur below -55mV?

Back

No, an action potential cannot occur below -55mV.

Front

What is the function of Schwann Cells?

Back

Schwann Cells produce myelin, which insulates axons and speeds up signal transmission.

Front

What is the role of axon terminals?

Back

Axon terminals release neurotransmitters to communicate with other neurons.

Front

What is the resting potential of a neuron?

Back

The resting potential is typically around -70mV, indicating a polarized state.
