Question 1

Sclera (External Layer)

Answer 1

Opaque white connective tissue that forms the “white of the eyeball”

It helps to maintain the shape of the eyeball and provides an attachment point for the extrinsic eye muscle.

Question 2

Cornea (Eternal Layer)

Answer 2

Structurally continuous with the sclera; modified to form a transparent layer that bulges anteriorly; contains no blood vessels.

Forms a clear window that is the major light-bending (refracting) medium of the eye.

Question 3

Choroid (Middle Layer)

Answer 3

A blood vessel-rich, dark membrane

The blood vessels nourish the other layers of the eye, and the melanin helps to absorb excess light.

Question 4

Ciliary Body (Middle layer)

Answer 4

Modification of the choroid that encircles the lens.

Contains the ciliary muscle and the ciliary process.

Question 5

Ciliary Muscle (Middle Layer)

Answer 5

Smooth muscle is found within the ciliary body.

Alters the shape of the lens with contraction and relaxation.

Question 6

Ciliary Process (Middle Layer)

Answer 6

Radiating folds of the ciliary muscle.

Capillaries of the ciliary process form the aqueous humor by filtering plasma.

Question 7

Retina (Inner Layer)

Question 8

Iris (Middle Layer)

Answer 8

the anterior portion of the vascular layer that is pigmented. It contains two layers of smooth muscle. (sphincter pupillae and dilator pupillae).

Question 9

Retina (Inner Layer) Pigmented layer

Answer 9

The outer layer of the that is composed of only a single layer of pigment cells

Absorbs light and prevents it from scattering in the eye. Pigment cells act as phagocytes for cleaning up cell debris and also store vitamin A needed for photoreceptor renewal.

Question 10

Lens

Question 11

Suspensory Ligament

Question 12

Macula Lutea

Question 13

Fovea Centralis

Question 14

Optic Nerve (CN II)

Question 15

Question 16

Ora Serrata

Question 17

Anterior Chamber of Eye

Question 18

Posterior Chamber of Eye

Question 19

Aqueous Humor

Question 20

Vitreous Humor

Question 21

Occipital Lobe

Question 22

Lateral Rectus Muscle

Answer 22

Moves eye laterally

Question 23

Medial Rectus Muscle

Answer 23

Moves eye medially

Question 24

Superior Rectus Muscle

Answer 24

Elevates eye and turns it medially

Question 25

Inferior Rectus Muscle

Answer 25

Depresses eye and turns it medially

Question 26

Inferior Oblique Muscle

Answer 26

Elevates eye and turns it laterally

Question 27

Superior Oblique Muscle

Answer 27

Depresses eye and turns it laterally
