Neurons Structure

Front

What is the soma of a neuron?

Back

The soma, or cell body, is the neuron's life support that contains the nucleus and organelles.

Front

What type of neuron carries information from the brain to the rest of the body?

Back

Motor Neuron.

Front

What is the primary function of the axon in a neuron?

Back

The axon carries information from the cell body to other neurons.

Front

What is the role of dendrites in a neuron?

Back

Dendrites receive electrical signals from other neurons and transmit them to the soma.

Front

What is the function of myelin sheaths?

Back

Myelin sheaths insulate the axon and increase the speed of electrical signals.

Front

In what direction does the electrical signal travel through a neuron?

Back

From dendrites, down the axon, and out the axon terminals.

Front

What are axon terminals?

Back

Axon terminals are the endpoints of an axon where neurotransmitters are released to communicate with other neurons.

Front

What is an interneuron?

Back

Interneurons are neurons that connect other neurons within the central nervous system.

Front

What is the difference between sensory neurons and motor neurons?

Back

Sensory neurons carry information from sensory receptors to the central nervous system, while motor neurons carry signals from the central nervous system to muscles and glands.

Front

What is the role of neurotransmitters?

Back

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