Neuroanatomy and glial cells come in many types (see, for example, the nervous system section of the list of distinct cell types in the adult human body). Neurons are the information-processing cells of the nervous system: they sense our environment, communicate with each other via electrical signals and chemicals called neurotransmitters across synapses, and produce our memories, thoughts and movements. Glial cells maintain homeostasis, produce myelin, and provide support and protection for the brain's neurons. Some glial cells (astrocytes) can even propagate intercellular calcium waves over long distances in response to stimulation, and release gliotransmitters in response to changes in calcium
Satellite glial cell will also be explored in order to determine the effect of these conditions. Additionally, the mechanisms behind neuronal-SGC communication is essentially unidentified, though it is likely that the various receptors both the neurons and SGCs have are used for chemical signaling, perhaps with P2Y. Ca and NO and their effects must also be observed to gain further understanding of interactions between the two types of cells. Finally, the possibility of an influence of SGCs on synaptic transmission within autonomic ganglia provides another direction for future research.
