Answer 1

1, 2, conjectiva
Layers of the cornea inlcude epithelium, stroma and endothelium, descemt's membrane and bowmans layer. conjectiva is a tissue that lines the inner eyelid and covers the sclera.
2,1, Lacrimal glans
lacrimal gland is called tear ducts situated in the outer corner of the eylid.
Lower and upper canaliculi joint with lacrimal sac following the arc of the eyelid.
Lacrimal sac in nasolacrimal duct formed by the lacrimal bone and frontal process of the maxilla.
3, 3, conjunctivitis
Inflammation of the conjunctiva is called conjunctivitis that is also called a pink eye.
Keratitis is an inflammtion of the cornea.
Dacryocystitis is an infection of the lacrimal sac.
Blepharitis is an inflammation of the eyelid.
4, 4, Extraocular muscle
there are six extraocular muscle control eye position and movement that are medial rectus, lateral rectus, inferior rectus, superior oblique, superior rectus, and inferior oblique.
Intraocular muscle includes ciliary muscle, dilator papillae, sphincter papillae, it shapes the lens and accommodates and control the flow of aqueous humor.
a palpebral muscle in the upper eyelid helps for closing, blinking and sleeping activity.
Vitreous chamber separates the lens and retina, it absorbs shocks to the eye and makes the retina in the position in the back wall of the eye.
