PSC 101 Lecture Notes - Lecture 7: Vitreous Body, Aqueous Humour, Ciliary Muscle
Document Summary
Anterior chamber: space filled with aqueous humour, which provides pressure to maintain shape of eyeball; allows nutrients and minerals to supply cells of cornea/iris, pupil: the opening in the middle of the iris. The size of the pupil can get bigger/smaller based on the iris relaxing/contracting respectively. The pupil modulates the amount of light able to enter the eyeball. The muscle that constricts/relaxes to change the size of the pupil: lens: bends the light so it goes to back of eyeball focuses light specifically on the fovea of the retina. Adjust how much it bends the light by changing its shape, using the suspensory ligaments: suspensory ligaments: attached to a ciliary muscle. *rest of the retina is covered in primarily rods: cones: detect color and discern high level of detail in what you are observing. Rod shaped: choroid pigmented black in humans, is a network of blood vessels that helps nourish the retina.
