Anatomy & Physiology of the Eye lab requirements

Flashcards covering the anatomy and physiology of the eye, including structures, functions, and disorders.

Lacrimal Apparatus

Includes lacrimal glands, excretory ducts, lacrimal puncta, lacrimal canaliculi, lacrimal sac, and nasolacrimal duct; responsible for tear production and drainage.

Extrinsic Eye Muscles

Muscles that control eye movements, including the medial rectus, superior rectus, inferior rectus, lateral rectus, superior oblique, and inferior oblique.

Sclera

The fibrous outer layer of the eye, providing protection and structure; posterior part.

Cornea

The clear, front outer part of the eye that refracts light.

Ciliary Body

Middle wall structure containing ciliary muscles that control lens shape and ciliary processes that secrete aqueous humor.

Iris

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

Conjunctivitis

An inflammation of the conjunctiva, often resulting in redness and irritation of the eye.

Cataract

A clouding of the lens, leading to decreased vision.

Glaucoma

A group of eye conditions that damage the optic nerve, often due to increased intraocular pressure.

Aqueous Humor

A clear fluid produced by the ciliary processes, filling the anterior cavity of the eye and providing nutrients to the eye structures.

Visual Pathway

The pathway of action potentials from the retina to the visual cortex, including the optic nerve, optic chiasma, optic tracts, and lateral geniculate body.

Macula Lutea

A small central spot in the retina where visual acuity is highest, containing a high density of cones.

Fovea Centralis

The center of the macula lutea with only cones, responsible for sharp central vision.

Optic Disc

The area on the retina where the optic nerve fibers exit the eye, known as the blind spot.
