Human Eye Post Dissection Reading

What is the primary function of the cornea in the human eye?

• To control the movement of the eyelid

• To process visual information into nerve impulses

• To refract light to help focus it on the retina

• To produce aqueous humor

Which part of the eye is responsible for converting light into nerve impulses?

• Lens

• Cornea

• Retina

• Ciliary muscle

What is the role of the vitreous humor in the eye?

• To maintain the shape of the eyeball

• To provide nutrients to the eye structures

• To connect the lens to the ciliary body

• To absorb light and prevent reflection

Where is the fovea located and what is its significance?

• In the anterior chamber, responsible for color vision

• In the posterior cavity, responsible for peripheral vision

• In the retina, responsible for high concentration of cones for sharp vision

• In the sclera, responsible for protecting internal structures

What is the function of the macula lutea in the eye?

• It controls the movement of the eye.

• It is responsible for night vision.

• It is the region of the retina with a great number of photosensitive cells.

• It produces the aqueous humor.

Which part of the eye is known as the "blind spot"?

• Macula lutea

• Optic disk

• Fovea centralis

• Lens

What is the primary role of the retina in the eye?

• To provide structural support to the eye.

• To convert light energy into nerve impulses.

• To regulate the amount of light entering the eye.

• To produce and drain aqueous humor.

Which cells in the retina are more numerous and determine motion and night vision?

• Cones

• Macula cells

• Rods

• Bipolar cells

What is the function of the bipolar layer in the retina?

• It synthesizes visual pigments.

• It connects to neuron fibers.

• It synapses with the rods and cones.

• It regulates the intraocular pressure.

What is the sclera commonly referred to as?

• The "black" of the eye

• The "white" of the eye

• The "color" of the eye

• The "iris" of the eye
