As they extend from the retina to the brain, nerve fibers…
from the nasal half of each retina cross to reach the opposite visual cortex
Constriction of the pupil is brought about by contraction of the…
circular muscle of the iris
During accommodation for near vision…
the iris dilates and lets in more light
In humans, both eyes focus on only one set of objects. This is called
binocular vision
Intraocular pressure is primarily due to the
aqueous humor
Most of the refraction of light entering the eye occurs at the
cornea
The anterior cavity contains
aqueous humor
The blind spot is the area where
the optic nerve exits the eye
The fibrous tunic is composed of the
sclera and cornea
The point of greatest visual acuity is the
central fovea
The white of the eye, which gives shape to the eyeball, makes it more rigid, and protects its inner parts is the
sclera
When entering a dark room on a sunny day, it takes some time to be able to see because
it takes time for the retina to rebuild its rhodopsin
Which cranial nerve carries visual impulses to the brain?
II
Which of the following is part of the vascular tunic of the eye?
