Compare and contrast the cornea, iris, pupil, lens, ciliary body, canal of Schlemm, fovea, posterior chamber, and anterior chamber.
cornea- lacks blood vessels, connective tissue of corea secrete tenomodulin (prevents blood vessel growth), lack immune cells. iris- disk shaped with muscle that controls size. modulate amount of light entering eye. color determined by # of pigment producing melanocytes. pupil- opening in eye. lens- lens that light passes through (can accomodate). ciliary body- encircles lens, contains musculature that adjusts the refractive power of lens. canal of Schlemm- drainage for aqueous humor. fovea-the cone density is highest and its central region is rod-free (sharp vision). posterior chamber- contains vitreous humor. anterior chamber contains aqueous humor.
