What type of cell is found in the PNS that regulates and stabilizes the cells environment?
A
Astrocytes
B
Schwann
C
Satellite
D
Ependymal
Explanation: 

Detailed explanation-1: -Satellite glial cells are a type of glia found in the peripheral nervous system, specifically in sensory, sympathetic, and parasympathetic ganglia.

Detailed explanation-2: -Neuroglia in the PNS Satellite cells – regulate nutrient and neurotransmitter levels around neurons in ganglia.

Detailed explanation-3: -In the PNS, the main glial cells are Schwann cells, satellite cells, and enteric glia. These cells differ and are classified according to their morphologies, distinct anatomical locations in the nervous system, functions, developmental origins, and unique molecular compositions.

Detailed explanation-4: -Satellite cells are small glia that surround neurons’ sensory ganglia in the ANS. These resemble the astrocytes of the CNS and assist in regulating the external chemical environment. PNS satellite glia are very sensitive to injury and may exacerbate pathological pain.
