The Unipolar Neuron

Front

What is the function of the cell body in a unipolar neuron?

Back

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

Front

What is the role of the peripheral process in a unipolar neuron?

Back

The peripheral process transmits sensory information from the periphery to the cell body.

Front

What is the trigger zone in a unipolar neuron?

Back

The trigger zone is the area where action potentials are initiated, typically located at the junction of the axon and the cell body.

Front

What is the function of the axon terminal in a unipolar neuron?

Back

The axon terminal releases neurotransmitters to communicate with other neurons or target cells.

Front

What is the role of dendrites in a unipolar neuron?

Back

Dendrites receive incoming signals from other neurons and transmit them to the cell body.

Front

What distinguishes a unipolar neuron from other types of neurons?

Back

A unipolar neuron has a single process that splits into two branches: one serving as the dendrite and the other as the axon.

Front

What type of signals do unipolar neurons typically transmit?

Back

Unipolar neurons primarily transmit sensory signals from the body to the central nervous system.

Front

How do unipolar neurons contribute to the nervous system?

Back

Unipolar neurons play a crucial role in sensory pathways, relaying information about touch, pain, and temperature.

Front

What is the significance of the myelin sheath in unipolar neurons?

Back

The myelin sheath insulates the axon, increasing the speed of action potential conduction.

Front

What is the structure of a unipolar neuron?

Back

A unipolar neuron consists of a single long axon with a cell body located off to the side.
