the outermost layer of the eye consisting mostly of collagenous connective tissue
what is the vascular tunic?
aka the uvea, it is the middle layer of the eye
what is the nervous tunic?
aka the retina, it is the innermost layer of the eye consisting of three layers of neurons; the layer closest to the uvea contains specialized neuronal cells that are sensitive to visible light

ciliary body
what is C?
the iris
what is D?
the pupil
what is E?
the optic disc
what is F and it's structure?
the macula lutea; high concentration of cone cells0 critical for visual acuity
what is G and its structure?
fovea centralis - central region of the macula lutea; highest concentration of cones and the source of sharpest vision
what is H?
optic nerve

the retina
what is the function of cones?
photoreceptors responsible for sensing bright light and color
what is the function of rods?
photoreceptors responsible for sensing light in a dim environment
what are constrictor pupillae?
smooth muscle cells arranged in a circle around the pupil - controlled by PNS
what are the dilator pupillae?
radially oriented myoepithelial cells which contract to dilate the pupil
what is the posterior chamber?
it is located between the lens and the iris containing aqueous humor
what are ciliary processes?
projections from the ciliary body covered in epithelium that produce aqueous humor; suspensory ligaments connect the ciliary processes to the lens
