Visual system

The fibrous layer of the eye is..

• A layer responsible for vision.
• The layer that contains the retina.
• Outermost layer of the eye

• The inner layer of the eye.

The cornea is...

• The cornea is a layer of fat behind the eye.
• The cornea is the colored part of the eye.
• Most anterior, transparent portion of the eye that is continuous with the sclera

• The cornea is a muscle that controls the pupil size.

The sclera is...

• The colored part of the eye.
• The transparent layer covering the front of the eye.
• The inner layer of the eyeball.
• White area of the eye; the site of attachment for the extraoccular muscles

The vascular layer of the eye is...

• The retina.
• The cornea.
• The sclera.
• Middle layer of the eye

The choroid is...

• Layer of highly vascularized CT in the vascular tunic of the eye

• a fluid-filled cavity in the eye
• a part of the retina that detects light
• a protective outer layer of the eye

The iris is..

• The outer layer of the eye that protects it.
• The transparent part of the eye that allows light to enter.
• Superficial to the ciliary body and visible in the anterior eye; contains pigment cells that gives us eye color

• The part of the eye that focuses light onto the retina.

The sphincter pupillae...

• Functions to reduce the diameter of the pupil

• nerve endings in the retina that detect light
• blood vessels in the sclera that regulate pressure
• muscle fibers in the cornea that dilate the pupil

The dilator pupillae...

• is a muscle that constricts the pupil.
• is a nerve that controls pupil size.
• is a gland that produces eye fluid.
• Functions to increase the diameter of the pupil

The pupil is...

• the colored part of the eye
• a type of lens in the eye
• the outer layer of the eye
• Hole at the center of the eye that allows light to enter

The ciliary body...

• The ciliary body regulates blood flow to the retina.
• The ciliary body is responsible for producing tears.
• The ciliary body controls the pupil size.
• Consists of the ciliary muscles and the ciliary processes
