Uvea with 14. Iris, 15. Ciliary body. The anterior segment or anterior cavity[ 1] is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. [ 2][ 3] Within the anterior segment are two fluid-filled spaces: the anterior chamber between the posterior surface of the cornea ...
The choroid, also known as the choroideaor choroid coat, is a part of the uvea, the vascularlayer of the eye. It contains connective tissues, and lies between the retinaand the sclera. The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm.[1]The choroid provides oxygenand ...
The elements composing the layer of rods and cones ( Jacob's membrane) in the retina of the eye are of two kinds, rod cells and cone cells, the former being much more numerous than the latter except in the macula lutea . Jacob's membrane is named after Irish ophthalmologist Arthur Jacob, who was the first to describe this nervous layer of the ...
The spot to the left of the centre is the macula. The grey, more diffuse spot in the centre is a shadow artifact. The fundus of the eye is the interior surface of the eye opposite the lens and includes the retina, optic disc, macula, fovea, and posterior pole. [1] The fundus can be examined by ophthalmoscopy [1] and/or fundus photography .

It is a small, ovoid, ventral projection of the thalamus where the thalamus ...
Anatomical terms of neuroanatomy. [ edit on Wikidata] The ophthalmic nerve ( CN V1) is a sensory nerve of the head. It is one of three divisions of the trigeminal nerve (CN V), a cranial nerve. It has three major branches which provide sensory innervation to the eye, and the skin of the upper face and anterior scalp, as well as other structures ...
