what statements are true about the anatomy of the eye? a. The sclera is the posterior four-fifths of the eyeball. It is a clear connective tissue that maintains the shape of the eyeball and provides a site for muscle attachment. b. The cornea is the anterior one-fifth of the eye. It is transparent and deflects light that enters the eye. c. The iris is smooth muscle regulated by the autonomic nervous system. It controls the amount of light entering the pupil. d. The eyeball has three chambers: anterior, posterior, and vitreous. The anterior and posterior chambers are filled with aqueous humor, which circulates and leaves by way of the scleral venous sinus.
