GENERAL HISTOLOGY

Detailed explanation-1: -Glial cells of the (b) peripheral nervous system include Schwann cells, which form the myelin sheath, and satellite cells, which provide nutrients and structural support to neurons.

Detailed explanation-2: -Glial cells are the most abundant cells in the human brain and have long been considered as passive supporting cells for neurons. In contrast to the extensive studies on various neuronal functions in the nervous system, we still have limited knowledge about glial cells.

Detailed explanation-3: -Glial cells are a type of cell that provides physical and chemical support to neurons and maintain their environment. Located in the central nervous system and peripheral nervous system, glial cells are sometimes called the “glue” of the nervous system, as well as neuroglia or just glia.

Detailed explanation-4: -Some glial cells function primarily as the physical support for neurons. Others provide nutrients to neurons and regulate the extracellular fluid of the brain, especially surrounding neurons and their synapses.
