Hint
Answer
Areas in between ciliary processes are called valleys of what?
Kuhnt

Supraciliaris
The 3 layers of the ciliary muscle are the longitudinal muscle fibers (of Brucke), the radial fibers, and what?
(Muller's) annular muscle
This layer of the ciliary body is continuous with the iris stroma.
Ciliary stroma
This layer of the ciliary body is continuous with the neural retina.
Nonpigmented ciliary epithelium
This layer of the choroid is the outermost layer and is a potential space between the sclera and choroidal vessels.
Suprachoroid
Parasympathetic stimulation of the choroidal vessels causes the release of NO and what?
Vasodilation
This layer of the choroid is a specialized fenestrated layer nearest to the retina and densest under the macula.
Choriocapillaris
This layer consists of 2 basement membranes, 2 collagenous zones (inner and outer) and an elastic layer in the center.
Bruch's membrane
What process is mainly responsible for production of aqueous (80-90%)?
Active secretion
This is an antioxidant is found 20X more in aqueous than blood.
Ascorbate
These specialized barriers prevent large molecules like proteins from entering the aqueous and help create the blood aqueous barrier.
Tight junctions
These arteries form the choroid (they branch from the ophthalmic artery).
Short ciliary arteries
The movement of which two ions primarily drive aqueous secretion?
Na+
