FBbt:00004896 (Fly Anatomy) |
| Definition |
A tubular structure which surrounds the ovarian basement membrane (tunica propria) around each ovariole (Cummings, 1974). The main part of the sheath is a layer consisting mainly of circular and longitudinal muscle fibers and tracheoles (Cummings, 1974). This is sandwiched between two thin, acellular elastic membranes (Cummings, 1974).[ FlyBase:FBrf0018806 FlyBase:FBrf0019876 FlyBase:FBrf0064777 FlyBase:FBrf0244732 ] |
