Question

Quizplus · Accepted Answer

Astrocytes are specialized cells that form the blood-brain barrier, which regulates the substances that can enter the brain from the bloodstream.

Answer: D 
 Microglia are immune cells found in the central nervous system that help protect the brain from injury and harmful substances.

Answer: K 
 Oligodendrocytes are a type of glial cell that produce myelin, the insulation that covers axons and speeds up the transmission of electrical signals in the nervous system.

Answer: P 
 Neurotransmitters are chemicals that transmit signals between neurons or from neurons to other cells, such as muscles or glands.

Answer: Q 
 Nodes of Ranvier are interruptions in the myelin sheath that allow for saltatory conduction, in which action potentials jump from one node to another and travel faster than they would along an unmyelinated axon.
