Neurons Structure & Neurotransmitters

Front

What is the function of the Axon in a neuron?

Back

The Axon transmits electrical impulses away from the cell body to other neurons or muscles.

Front

What is the role of Dendrites in a neuron?

Back

Dendrites receive signals from other neurons and convey this information to the cell body.

Front

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

Back

The Cell Body contains the nucleus and organelles, and it integrates incoming signals.

Front

What is the purpose of the Myelin Sheath?

Back

The Myelin Sheath insulates the axon and increases the speed of electrical impulses.

Front

What are Nodes of Ranvier?

Back

Nodes of Ranvier are gaps in the Myelin Sheath that facilitate rapid signal transmission.

Front

What is a Synaptic Bulb/Knob?

Back

The Synaptic Bulb/Knob is the end of an axon that releases neurotransmitters into the synapse.

Front

Define neurotransmitter.

Back

A neurotransmitter is a chemical messenger that transmits signals across a synapse from one neuron to another.

Front

What is the function of Schwann Cells?

Back

Schwann Cells produce the Myelin Sheath around peripheral nerves.

Front

What is the significance of the Nucleus in a neuron?

Back

The Nucleus contains the genetic material and controls the cell's activities.

Front

What is the gap between neurons called?

Back

The gap between neurons is called the synapse.
