Word Origin for retina
C14: from Medieval Latin, perhaps from Latin rēte net
late 14c., from Medieval Latin retina "the retina," probably from Vulgar Latin (tunica) *retina, literally "net-like tunic," on resemblance to the network of blood vessels at the back of the eye, and ultimately from Latin rete "net" (see reticulate (adj.)). The Vulgar Latin phrase might be Gerard of Cremona's 12c. translation of Arabic (tabaqa) shabakiyyah "netlike (layer)," itself probably a translation of Greek amphiblestroeides (khiton).
The light-sensitive membrane that lines the inside of the back of the eyeball and connects to the brain by the optic nerve. The retina of vertebrate animals contains rods and cones, specialized cells that absorb light.
