adult proximal lamina satellite glial cell

ID: FBbt_00100524

Glial cell found in the proximal part of the cell body rind of the lamina. It is located in a layer between the distal satellite glial cells and the epithelial glial cells (Kremer et al., 2017). It originates from the outer optic anlage of the larva (Edwards et al., 2012). They are thin and dense, having a smaller size and more variable orientation along the anterior-posterior axis than the distal lamina satellite glia (Kremer et al., 2017). These glial cells invest the photoreceptor axon bundles and the necks of monopolar neurons (Edwards and Meinertzhagen, 2010). On their distal surface, they form pockets for the neuronal cell bodies, on their proximal surface, they send protrusions into the neuropil (Kremer et al., 2017). There is approximately one proximal satellite glial cell for every 2-3 groups of monopolar cell bodies (Edwards et al., 2012) and around 250 of these cells per optic lobe (Kremer et al., 2017).

Sometimes referred to as interface glia (Edwards and Meinertzhagen, 2010), as they are found at the interface between the cell body rind and the neuropil (Kremer et al., 2017). Not to be confused with interface glia found in the larval CNS.
