parts of the neuroepithelium	pars ciliary retinae (covers ciliary body); pars iridicae retinae (covers iris)
What are the 3 chambers of the eye?	Anterior, posterior, and vitreous
anterior and posterior chambers are filled with ___ humor	aqueous
the vitreous chamber is filled __ humor	vitreous
this chamber is between the cornea and the iris	anterior
this chamber is between the iris and the vitreous body that contains the lens	posterior
this chamber is between the lens and the retina	vitreous
components of the orbital fascia	periobita, bulbar sheath, and fascia sheath of the extraocular muscles
connective tissue that is connected to the external dura sheet of the optic nerve	periobit
lies directly on the sclera, AKA the tenon's capsule	bulbar sheath
where optic nerve components exit the orbital fascia	area cribosa
the sclera is comprised of ___ ____ CT	dense irregular
the thinnest part of the sclera is at the ___ and the thickest part is at the ___	equator; limbus
next to the choroid, elastic fibers are dominant. That is the ___ ____ ___	lamina fusca sclerae
What are the 5 layers of the cornea?	Anterior epithelium, Sub-epithelial basement membrane, Substansia propria (stroma), posterior limiting lamia, and posterior epithelium (corneal endothelium)

junction of the sclera and the cornea; transition from dense regular CT (cornea) to dense irregular CT (sclera)	limbus
function of the vascular tunic or uvea	nourishment; adjustment of the lens; accommodation (iris/pupil)
What is the main function of the choroid?	to nourish the retina

what are the 2 projected processes of the ciliary body?	pars plicata (folded) and pars plana (straight)
ciliary body epithelium is a continuation of the ___	retina
