Exam Questions With Correct Answers
100% Verified.
Which sense does not have a sense organ - Answer✔Touch
What are the outer layers of the eye? - Answer✔Sclera, Cornea, and aqueous humor
Describe the sclera. - Answer✔It is the posterior portion of the eye, aka the white of the eye
Describe the cornea. - Answer✔It is the anterior of the eye, and it is where light enters
Describe the aqueous humor. - Answer✔It fills the space between the cornea and the lens
What are the middle layers of the eye? - Answer✔Choroid, ciliary body, iris, pupil and lens
Describe the choroid. - Answer✔It is darkly covered on the posterior. It prevents light from
dispersing throughout the eye. It gives blood to the layers of the eye.
Describe the Ciliary Body - Answer✔Anterior portion. It is a muscle that attaches to the lens to
change the shape of the lens
Describe the iris - Answer✔It controls the amount of light that enters the pupil. It uses muscle
fibers to contract or dilate based on the amount of environmental light.
Describe the pupil - Answer✔It is the hole in the center of the iris
Describe the lens - Answer✔It is posterior to the iris and pupil. Ciliary muscles attach around
the lens
What are the inner layers of the eye? - Answer✔Retina and vitreous body
Describe the retina - Answer✔It has photoreceptors, rods and cones.
What is a rod? - Answer✔It is stimulated in dim light. They do not generate sharp or colored
images.
What is a cone? - Answer✔It is stimulated in bright light and it helps to detect color.

Describe the vitreous body - Answer✔It is posterior to the lens and it holds the retina to the
choroid
How does light enter from the environment to the brain? - Answer✔It starts in the cornea, goes
to the aqueous humor, then the lens, vitreous humor, posterior surface of the retina, and the
photoreceptors detect the light.
How does light enter from the environment to the brain using the left visual field? -
Answer✔Information is gathered from the left side of the environment on the left side from
both the left and right eyes and it is reflected onto the retina. It comes in through the optic
nerve and at the optic chiasm, medial fibers cross to the other side of the brain in the optic
tracts. It travels through LGN of thalamus and is sent through optic radiations and goes into
right side of occipital lobe.
What is the nasal visual field? - Answer✔It is closest to the nose. It creates the binocular visual
field and is the reason we can see 3D because of the visual fields overlapping.
What is the peripheral visual field? - Answer✔It is the lateral side of each eye
What is the left visual field? - Answer✔It gets information from the left side of the environment
and then is eventually interpreted on the right side of the brain
What would an injury to the right occipital lobe cause? - Answer✔A bilateral left visual field cut
What would an injury to the right optic nerve cause? - Answer✔Blindness in the right eye
What is the medial rectus? - Answer✔It turns the eye medially.
Which cranial nerve is the medial rectus? - Answer✔CNIII
What is the inferior rectus? - Answer✔It depresses the eye and moves the eye medially
What cranial nerve is the inferior rectus? - Answer✔CNIII
What is the superior rectus? - Answer✔It elevates the eye and moves the eye medially
What cranial nerve is the superior rectus? - Answer✔CNIII
What is the inferior oblique? - Answer✔It moves the eye laterally and gives external rotation
What cranial nerve is the inferior oblique? - Answer✔CNIII
What is the superior oblique? - Answer✔It gives the eye internal rotation, depresses the eye
and moves the eye laterally
What cranial nerve is the superior oblique? - Answer✔CNIV
What is the lateral rectus? - Answer✔It turns the eye laterally
