Labeling the parts of a Neuron

Front

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

Back

The Cell Body (Soma) is the part of the neuron that contains the nucleus and organelles, responsible for maintaining the cell's health and function.

Front

What is the function of Dendrites in a neuron?

Back

Dendrites are the branched extensions of a neuron that receive signals from other neurons and transmit them to the cell body.

Front

What is the Axon in a neuron?

Back

The Axon is a long, thin structure that transmits electrical impulses away from the cell body to other neurons or muscles.

Front

What is the Myelin Sheath?

Back

The Myelin Sheath is a fatty layer that surrounds the axon, insulating it and speeding up the transmission of electrical signals.

Front

What role do neurotransmitters play in neuron communication?

Back

Neurotransmitters are chemical messengers released by neurons to transmit signals across synapses to other neurons.

Front

What is a synapse?

Back

A synapse is the junction between two neurons where communication occurs through neurotransmitters.

Front

How do neurons transmit signals?

Back

Neurons transmit signals through electrical impulses called action potentials that travel along the axon.

Front

What is the importance of the myelin sheath?

Back

The myelin sheath increases the speed of electrical impulses along the axon and protects the axon from damage.

Front

What is the difference between sensory neurons and motor neurons?

Back

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

Front

What is the role of the nucleus in a neuron?

Back

The nucleus contains the cell's genetic material and controls cellular activities, including growth and metabolism.
