Amphicyte
Definition
A flattened, satellite-type glial cell that structurally surrounds and protects the body of neurons within the spinal and autonomic nerve ganglia of the peripheral nervous system. These capsular satellite cells play an essential role in maintaining the biochemical microenvironment, providing trophic support, and ensuring the electrical insulation of the neuronal cell body.
