Anatomical terms of microanatomy

Satellite glial cells, formerly called amphicytes,[1] are glial cells that cover the surface of neuron cell bodies in ganglia of the peripheral nervous system. Thus, they are found in sensory, sympathetic, and parasympathetic ganglia.[2][3] Both satellite glial cells (SGCs) and Schwann cells (the cells that ensheathe some nerve fibers in the PNS) are derived from the neural crest of the embryo during development.[4] SGCs have been found to play a variety of roles, including control over the microenvironment of sympathetic ganglia.[3] They are thought to have a similar role to astrocytes in the central nervous system (CNS).[3] They supply nutrients to the surrounding neurons and also have some structural function. Satellite cells also act as protective, cushioning cells. Additionally, they express a variety of receptors that allow for a range of interactions with neuroactive chemicals.[5] Many of these receptors and other ion channels have recently been implicated in health issues including chronic pain[6] and herpes simplex.[7] There is much more to be learned about these cells, and research surrounding additional properties and roles of the SGCs is ongoing.[8]
