Flashcards in The anterior segment (front of eye) Deck (26)
The clear membrane at the front of the globe that begins the process of focusing light that the eye receives is called
What are the 5 layers of the cornea?
Listed from the outside surface in:
1. Corneal epithelium
2. Bowman's membrane
3. Corneal stroma
4. Descemet's membrane
5. Corneal endothelium
The outermost corneal layer, providing defense against injury and infection is
The _______ acts as an anchor for the epithelial layer
The main body of the cornea, contributing to the cornea's rigidity is the
The fourth layer of the cornea contributing to its rigidity is the
The cells of the ______ act as pumps to maintain a proper fluid balance within the cornea
The white tissue surrounding the cornea is a continuation of the fibrous outer layer that forms the main structural component of the globe, protecting the intraocular contents. This tissue is called
The junction between the sclera and the cornea is the
The small compartment between the cornea and the iris that is filled with aqueous humor
The junction of the cornea and the iris, from which aqueous humor leaves the eye is
Anterior Chamber Angle
aka Filtration angle
A structure that drains the aqueous humor from the anterior chamber after it has flowed through the trabecular meshwork is
Canal of Schlemm
The sponge-like structure that filters the aqueous humor from the anterior chamber and controls its rate of flow out of the eye is the
What is the main vascular compartment of the eye?
The Uvea/Uveal Tract
What are the three parts of the uveal tract?
2. ciliary body
A colored diaphragm of tissue that is stretched across the rear of the anterior chamber behind the cornea is
What is the iris muscle that dilates the pupil in reduced light conditions? Fibers from this muscle stretch from the pupil to the outer boundaries of the iris
What is the name of the muscle that encircles the pupil and makes the pupil smaller in response to bright light?
The space between the back of the iris and the front of the vitreous where the crystalline lens is suspended is?
The Posterior Chamber
A band-like structure of muscle and secretory tissue that extends from the edge of the iris and encircles the inside of the sclera is
The ciliary body
The inner surface of the ciliary body is arranged in folds, rows, or ridges called
The muscle fibers in the ciliary body form the
The 3rd part of the uveal tract, the ______, is a continuation of the ciliary body in the form of a layer of tissue that lies between the sclera and the retina
The transparent structure located immediately behind the iris, suspended in the posterior chamber, is the
The lens is suspended by transparent fibers called
