General Information
Term neuropil glial cell ID (Ontology) FBbt:00001303 (Fly Anatomy)
Definition Glial cell of the CNS that is associated with neuropil compartments, including synaptic and tract neuropil (Hartenstein, 2011; Omoto et al., 2015; Kremer et al., 2017). These cells have their cell bodies located in the neuropil glial sheath, between the neuropil and the cell body rind, and many of them extend processes into the neuropil (Hartenstein, 2011; Omoto et al., 2015). Two subtypes have been identified, the reticular (astrocyte-like) and ensheathing glia (Hartenstein, 2011; Omoto et al., 2015), which both function in ionic and neurotransmitter homeostasis (Kremer et al., 2017).[ FlyBase:FBrf0082171 FlyBase:FBrf0214261 FlyBase:FBrf0229106 FlyBase:FBrf0234767 ]
Also Known As "neuropil associated CNS glial cell" ; "neuropil associated glial cell" ; "neuropil-associated CNS glial cell" (for all, see Synonyms field below)
