General Information
Term perineurial glial cell ID (Ontology) FBbt:00005153 (Fly Anatomy)
Definition Glial cell that forms part of the perineurial sheath forming the outer layer of the nervous system. These cells divide extensively to increase in number as the nervous system expands during development (Kremer et al., 2017).[ FlyBase:FBrf0234767 ]
Also Known As "outer perineural sheath cell" ; "perineurial sheath cell" ; "perineurial sheath glial cell" (for all, see Synonyms field below)
