Neuron anatomy

Front

What is the function of the axon in a neuron?

Back

The axon carries electrical impulses away from the cell body to other neurons or muscles.

Front

What part of the neuron receives signals from other neurons?

Back

Dendrites receive signals from other neurons.

Front

What is a synapse?

Back

A synapse is a junction at which a neuron meets another cell, allowing for communication between them.

Front

What is the role of axon terminals?

Back

Axon terminals store and release neurotransmitters into the synapse.

Front

What is the cell body of a neuron?

Back

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

Front

What is myelin sheath?

Back

Myelin sheath is a fatty layer that insulates axons and speeds up the transmission of impulses.

Front

What are Schwann cells?

Back

Schwann cells are glial cells that form the myelin sheath around peripheral nerves.

Front

What is the difference between an axon and a dendrite?

Back

An axon carries impulses away from the cell body, while dendrites carry impulses toward the cell body.

Front

What are Nodes of Ranvier?

Back

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

Front

What is the significance of neurotransmitters?

Back

Neurotransmitters are chemicals that transmit signals across the synapse from one neuron to another.
