Nervous System Check In Flashcardizz

Front

What is the function of ependymal cells in the nervous system?

Back

Ependymal cells produce cerebrospinal fluid in the brain and spinal cord.

Front

Which neurotransmitter is found at low levels in patients with Parkinson's Disease?

Back

Dopamine.

Front

What is the myelin sheath and its role in the nervous system?

Back

The myelin sheath is an insulating material that forms a layer around the axon of a neuron, enabling electrical signals to travel down the axon at higher speeds.

Front

Define neurotransmitter and its function in the nervous system.

Back

A neurotransmitter is a chemical produced by neurons that carries messages to other neurons.

Front

What is the role of dendrites in a neuron?

Back

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

Front

What is the primary function of the central nervous system (CNS)?

Back

The central nervous system processes information and coordinates responses throughout the body.

Front

What are the two main types of cells in the nervous system?

Back

Neurons and glial cells.

Front

How does the myelin sheath affect nerve signal transmission?

Back

The myelin sheath increases the speed of nerve signal transmission by allowing signals to jump between nodes of Ranvier.

Front

What is the role of glial cells in the nervous system?

Back

Glial cells support, protect, and maintain the health of neurons.

Front

What is the difference between an axon and a dendrite?

Back

An axon transmits signals away from the neuron, while dendrites receive signals from other neurons.
