Superior and Inferior oblique muscles
Eyelids (Palpebrae)
Thin folds of skin that cover and protect the eye.
Help spread tears over the surface of the eye to keep it moist.
Eyelashes
Hairs on the edge of the eyelids that trap dust and debris.
Conjunctiva
A thin, transparent mucous membrane covering the inner surface of the eyelids and the front surface of the sclera (white part of the eye).
Lacrimal Apparatus
Produces and drains tears.
Includes:
Lacrimal gland (produces tears)
Lacrimal canaliculi (small channels that drain tears)
Lacrimal sac
Nasolacrimal duct (drains tears into the nose)
Extraocular Muscles
Six muscles attached to the eyeball that control eye movement:
Superior, Inferior, Medial, Lateral rectus muscles
