General Information
Term testis sheath ID (Ontology) FBbt:00004955 (Fly Anatomy)
Definition This testis sheath consists of an outer epithelial layer of pigment cells and a thin, circumferential layer of muscle cells, separated from each other by a basal lamina. A second basal lamina separates the muscle layer from the testis lumen. It forms during the pupal stage both from cells of the testis and from cells of the genital disc (Kozopas et al., 1998).[ FlyBase:FBrf0064778 FlyBase:FBrf0102352 ]
