Eye and Ear Anatomy

A set of flashcards covering key terms and concepts related to eye and ear anatomy, intended for review before the exam.

Conjunctiva

The thin, transparent tissue covering the outer surface of the eye, nourished by tiny blood vessels.

Levator palpebrae superioris

A muscle that elevates the upper eyelid.

Iris

The colored part of the eye that controls the size of the pupil.

Cornea

The transparent front part of the eye that covers the iris and pupil, helping to focus light.

Ciliary body

The part of the eye that connects the iris to the choroid and contains muscles to control lens shape.

Aqueous humor

The clear fluid in the anterior chamber of the eye, providing nutrients and maintaining intraocular pressure.

Lens

The transparent structure in the eye that helps focus light onto the retina.

Retina

The light-sensitive layer of tissue at the back of the eye containing photoreceptors.

Vestibular system

Parts of the inner ear involved in balance and spatial orientation.

Cochlea

A spiral-shaped organ in the inner ear responsible for hearing.

Photoreceptors

Cells in the retina (rods and cones) that detect light.

Myopia

A vision condition where close objects appear clearly, but distant ones don't (nearsightedness).

Hyperopia

A vision condition where distant objects may be seen more clearly than close ones (farsightedness).

Cataract

A clouding of the lens in the eye that affects vision.

Optic nerve

The nerve that transmits visual information from the retina to the brain.

Basilar membrane

A structure in the cochlea that plays a crucial role in hearing; it vibrates in response to sound.

Olfactory bulb

The neural structure involved in the sense of smell, processing odors received from the nasal cavity.

Taste buds

Sensory organs on the tongue responsible for detecting taste.
