| Question | Answer |
| function of the lacrimal apparatus | to produce fluid that lubricates the eye |
| What are the 3 tunics of the eye | Outer tunic, Middle tunic, and inner tunic |
| The outer tunic includes the ___ and the ___; made of a ___ coat | sclera; cornea; fibrous |
| the middle tunic includes the ___, ___ ___, and the ___; ___ tunic | choroid; ciliary bodies; iris; vascular |
| the inner tunic includes the ____; ___epithelium | retina; neuro(epithelium) |
| 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) |
| Main layer of the cornea; made of dense regular CT; collagen fibers are always parallel to the corneal surface | substansia propria (stroma) |
| 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 |
| external surface of the choroid is connected to ___ while the internal surface is next to and attached to pigmented layer of the ___ | sclera; retina |
| What are the 5 layers of the choroid? | Basal complex, choriocapillary layer, tapetum lucidum, vascular layer, and supra choroid layer |
| this layer of the choroid contains pigmented rod cells that lay parallel and are oriented in their long axis | tapetum lucidum (choroid CT) |
| the ___ ____ is a direct anterior continuation of the choroid | ciliary body |
| the ciliary body begins at the __ ___ | ora serrata |
| all the choroid layers continue into the cilliary body except ___ ___ and _____ layer | tapetum lucidum; choriocapillary |
| 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 |
| what is the function of the ciliary muscle? | to adjust the thickness of the lens |
| the ciliary processes produce ___ ____ | aqueous humor |
| controls the diameter of the pupil | iris |
| the deep vascular layer of the iris contains bundles of collagen and many ___ | melanocytes |
| types of cells found within the retina | rods, cones, horizontal cells, Amacrine cells, bipolar cells, and ganglion cells |
| what are the 3 main layers of the retina | photoreceptor layer, inner nuclear layer, and ganglion cell layer |
| the optic disc as an increased number of ___ | cones |
| most acute vision center | optic disc |
| forms the refractive media of the eyes | lens |
| where are goblet cells present in the eye? | conjunctiva |
| describe the epithelium of the conjunctiva | psuedostratified columnar or transitional |
