Nervous System Functions Study Guide

Front

What is a Unipolar neuron?

Back

A type of neuron with one long axon extending from the soma, typically found in sensory neurons.

Front

What is a Multipolar neuron?

Back

A type of neuron with many dendrites and one axon, commonly found in the brain and spinal cord.

Front

What do Motor neurons do?

Back

They carry impulses from the central nervous system to glands and muscles.

Front

What is the structural classification of a neuron?

Back

It refers to the physical structure of the neuron, such as unipolar, bipolar, or multipolar.

Front

What is the function of Oligodendrocytes?

Back

They attach up to 150 neurons together and provide support and insulation to axons in the central nervous system.

Front

What is the role of sensory neurons?

Back

They carry signals from sensory receptors to the central nervous system.

Front

What is an Interneuron?

Back

A type of neuron that connects sensory and motor neurons within the central nervous system.

Front

What is the function of the myelin sheath?

Back

It insulates axons and increases the speed of electrical impulses along the neuron.

Front

What is the difference between the central nervous system and the peripheral nervous system?

Back

The central nervous system consists of the brain and spinal cord, while the peripheral nervous system includes all other neural elements.

Front

What is synaptic transmission?

Back

The process by which neurotransmitters are released from one neuron and bind to receptors on another neuron.
