Eye Anatomy

Olfactory bulb

A structure in the brain responsible for the sense of smell, located at the anterior part of the brain.

Olfactory nerves

Nerves that carry sensory information from the olfactory bulb to the brain.

Cranial Nerve II

The optic nerve responsible for transmitting visual information from the eyes to the brain.

Optic chiasm

The point in the brain where the optic nerves from both eyes cross over.

Sclera

The white outer covering of the eyeball that provides protection and structure.

Cornea

The clear front part of the eye that covers the iris, pupil, and anterior chamber, allowing light to enter.

Choroid

The middle layer of the eye containing blood vessels that supply nutrients to the retina.

Retina

The innermost layer of the eye that contains photoreceptor cells enabling vision.

Iris

The colored part of the eye that controls the size of the pupil and hence the amount of light that enters the eye.

Pupil

The opening in the center of the iris that allows light to enter the eye.

Ciliary body

A structure in the eye that contains muscle fibers for adjusting the shape of the lens.

Macula lutea

The area on the retina responsible for sharp, detailed central vision.

Fovea

The central part of the macula responsible for the sharpest vision.

Optic disc

The point on the retina where the optic nerve exits, resulting in a blind spot.

Blind spot

The area of the retina without photoreceptor cells, where no visual information is processed.
