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
Perisynaptic schwann cells These proteins are seen in other glial cells such as Myelinating Schwann cells and Neural Crest cells. While the lineage of non-Myelinating Schwann cells is known from neural crest cells, the exact development of PSCs from non-Myelinating Schwann cells is not fully understood. Synaptogenesis is the formation of a synapse and in this case the Neuromuscular Junction is of interest. In this section, the focus is on the development of the NMJ from the outgrowth of axons during development. As mentioned in the development section, Schwann cell precursors accompany growing axons as they reach their associated muscles. It is now
