Glutamate receptor Glutamate receptor Glutamate receptors are synaptic and non synaptic receptors located primarily on the membranes of neuronal and glial cells. Glutamate (the conjugate base of glutamic acid) is abundant in the human body, but particularly in the nervous system and especially prominent in the human brain where it is the body's most prominent neurotransmitter, the brain's main excitatory neurotransmitter, and also the precursor for GABA, the brain's main inhibitory neurotransmitter. Glutamate receptors are responsible for the glutamate-mediated postsynaptic excitation of neural cells, and are important for neural communication, memory formation, learning, and regulation. Glutamate receptors are implicated in a number
Perisynaptic schwann cells cells of which Perisynaptic Schwann cells are a subset. Neural crest cells are found in the dorsal neural tube from which nerves and glia alike grow and Neural crest cells are the precursors to many various tissue types including enteric neurons and glia. Schwann cell precursors (a first derivative of Neural crest cells) are present as the nerve axon grows from the dorsal neural tube, but it has been shown that these glial precursors are not essential to axonal growth. The transition from neural crest cells to Schwann cell precursors is characterized by Sox10 and generally occurs around embryonic day
