GENERAL HISTOLOGY

Detailed explanation-1: -Glial cells are far more numerous than neurons and, unlike neurons, are capable of mitosis. For more information about anatomy of brain and CNS, go to the Nervous System section of the Anatomy & Physiology module on this Website.

Detailed explanation-2: -Glia. While glia are often thought of as the supporting cast of the nervous system, the number of glial cells in the brain actually outnumbers the number of neurons by a factor of ten. Neurons would be unable to function without the vital roles that are fulfilled by these glial cells.

Detailed explanation-3: -As a whole, glial cells are the most abundant cells in the central nervous system. The most notable glial cells include oligodendrocytes, Schwann cells, astrocytes, microglia, and ependymal cells.

Detailed explanation-4: -However, neurons differ from other cells in the body because: Neurons have specialize cell parts called dendrites and axons. Dendrites bring electrical signals to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process.

Detailed explanation-5: -Unlike most cell types, neurons are believed to have permanently blocked their capacity to proliferate once they are differentiated, being typically found in a quiescent state in the adult nervous system.
