Front

What are microglia?

Back

Small cells in the CNS that engulf and destroy microbes and cellular debris.

Front

What is a synapse?

Back

The entire junction between two nerves or a nerve and another structure.

Front

What primarily composes white matter in the nervous system?

Back

Axons.

Front

What do ependymal cells produce?

Back

Cerebrospinal fluid in the brain and spinal cord.

Front

What are the main types of neuroglia?

Back

Astrocytes, oligodendrocytes, microglia, and ependymal cells.

Front

What is the role of astrocytes?

Back

Support neurons, maintain the blood-brain barrier, and regulate blood flow.

Front

What is the function of oligodendrocytes?

Back

To produce myelin sheaths that insulate axons in the CNS.

Front

What is the difference between gray matter and white matter?

Back

Gray matter consists mainly of neuronal cell bodies, while white matter consists mainly of myelinated axons.

Front

What is the role of neurotransmitters?

Back

Chemicals that transmit signals across a synapse from one neuron to another.
