ZFA:0005562 lamina basilis EMAPA:37450 UBERON:0003957 vitreous lamina Bruch's membrane consists of five layers (from inside to outside): 1. the basement membrane of the retinal pigment epithelium; 2. the inner collagenous zone; 3. a central band of elastic fibers; 4. the outer collagenous zone; 5. the basement membrane of the choriocapillaris. The retinal pigment epithelium transports metabolic waste from the photoreceptors across Bruch's membrane to the choroid[WP] GAID:914 lamina choroideae basalis SCTID:280652000 Bruch's basal membrane basal lamina of choroid A transparent, nearly structureless innermost layer of the choroid in contact with the pigmented layer of the retina.
