Question

Quizplus · Accepted Answer

Astrocytes are the most responsible cells for preventing bacteria from entering the fluids of the brain. They are a type of glial cell that forms a protective barrier called the blood-brain barrier. This barrier prevents harmful substances, including bacteria, from entering the brain and damaging its delicate tissues. Satellite cells are found in the peripheral nervous system and are involved in supporting and protecting neurons. Schwann cells and oligodendrocytes are also involved in supporting and protecting neurons, but they do not play a direct role in preventing bacteria from entering the fluids around the brain.
