| Consists of choroid, ciliary body, and iris.
170
Choroid
Inner lining of the sclera. Contains blood vessels to nourish the eye.
171
Ciliary body
Lies at the anterior edges of the choroid body and consists of ciliary muscles and the ciliary process.
172

173
Ciliary process
Produces a watery substance called aqueous humor which bathes the anterior region of the eye
174
Iris
Circular colored portion of the eye.
175
Pupil
Regulates the amount of light that enters the eye. In bright light muscles constrict the pupil. In dim light they relax. Radial muscles dilate the pupil when a person is stressed or excited.
176
Retina
Inner layer of the eye.
Several layers of nervous tissue containing cones and rods, which are the cells that transform light into nerve impulses.
177
Fovea centralis
Cones responsible for central and bright light vision are concentrated here. Located in a small yellowish area called the macula lutea
178

Small area of the retina w no cones or rods and does not produce any visual images. Point at which the optic nerve begins and the entry point for the major blood vessels of the eye.
179
Lens
Not considered one of the layers of the eye. Posterior to the iris and held in place by suspensory ligaments.
180

```
191

By the vibration of the stapes against the oval window, causing hair cells in the organ of Corti to sway and stimulate the underlying nerve fibers that create nerve impulses which travel to the temporal lobe of the brain
