retina

The innermost of the three tunics of the eyeball. It consists of three parts: 1) pars optica-retinae 2) pars ciliaris 3) pars iridica retinae. It contains: 1) the photosensitive layer of rods & cones & their neural connections that gather light & convert it into electrical nerve impulses, transmitted through the optic nerve. 2) retinal pigment epithelium & its basal lamina called Bruch's membrane, which together maintain the integrity of the barrier between the choroid & the retina
