Term FBbt:00100504 ID (Ontology) FBbt:00100504 (Fly Anatomy)
Definition Glial cell of the adult central nervous system that elaborates along the outer surface of its associated neuropil. Glia of this class may also surround neuropil bundles such as commissures or tracts. There are over 1000 of these in the adult central nervous system, some of which are descendants of larval ensheathing glia (Pogodalla et al., 2021).[ FlyBase:FBrf0206543 FlyBase:FBrf0234767 FlyBase:FBrf0251788 ]
Also Known As "adult EG" ; "adult ensheathing neuropil associated glial cell" ; "adult fibrous lamellar neuropil associated glial cell" (for all, see Synonyms field below)
