Eye Anatomy and Physiology

To look at a distant object the Ciliary Muscles ______ which ______ the Zonular Fibers, and causes the lens to _____

• contract / puts slack on / recoil and thicken

• contract / pull on / recoil and thicken

• relax / puts slack on / stretch and thin

• relax / pull on / stretch and thin

To look at a nearby object the Ciliary Muscles ______ which ______ the Zonular Fibers, and causes the lens to _____

• contract / puts slack on / recoil and thicken

• contract / pull on / recoil and thicken

• relax / puts slack on / stretch and thin

• relax / pull on / stretch and thin

The pupil will dilate (enlarge) when:

• Enviornmental Light is High / Sympathetic Nervous System is Activated

• Enviornmental Light is Low / Sympathetic Nervous System is Activated

• Enviornmental Light is High / Parasympathetic Nervous System is Activated

• Enviornmental Light is Low / Parasympathetic Nervous System is Activated

The pupil will constrict when:

• Enviornmental Light is High / Sympathetic Nervous System is Activated

• Enviornmental Light is Low / Sympathetic Nervous System is Activated

• Enviornmental Light is High / Parasympathetic Nervous System is Activated

• Enviornmental Light is Low / Parasympathetic Nervous System is Activated

Rods are mostly located

• Around the edges (periphery) of the retina

• In the center of the retina

• In the Anterior Chamber

• In the Choroid

Cones are mostly located

• Around the edges (periphery) of the retina

• In the center of the retina

• In the Anterior Chamber

• In the Choroid

Rods and Cones are both

• Chemoreceptors

• Photoreceptors

• Thermoreceptors

• Mechanoreceptors

• Nociceptors

• High Resolution and Greyscale

• Low Resolution and Greyscale

• Low Resolution and Color

• High Resolution and Color

The vision provided by Cones

• High Resolution and Greyscale

• Low Resolution and Greyscale

Rods are mostly responsible for

• your peripheral (side) vision

• your central vision

• Lens Accommodation

• Retinal Mapping
