!Eyes
!!Anatomical overview
The human eye is a complex optical system which __collects light__ from the surrounding environment, __regulates__ its intensity through a diaphragm, __focuses__ it through an adjustable assembly of lenses to form an image, __converts__ this image into a set of electrical signals, and transmits these signals to the ((Nervous - Brain|brain)) through complex neural pathways that connect the eye via the __optic nerve__ to the visual cortex and other areas of the brain.

The eye is made up of three coats, enclosing three transparent structures. 
*The outermost layer, known as the __fibrous tunic__, is composed of the ((Sensory - Eyes - Cornea|cornea)) and sclera. 
*The middle layer, known as the vascular tunic or __uvea__, consists of the ((Sensory - Eyes - Chorioid|choroid)), ciliary body, and ((Sensory - Eyes - Iris|iris)). 
*The innermost is the __((Sensory - Eyes - Retina|retina))__, which gets its circulation from the vessels of the choroid as well as the retinal vessels, which can be seen in an ophthalmoscope.

Within these coats are the aqueous humour, the ((Sensory - Eyes - Vitreous Body|vitreous body)), and the flexible __((Sensory - Eyes - Crystalline Lens|lens))__. The aqueous humour is a clear fluid that is contained in two areas: the anterior chamber between the cornea and the iris, and the posterior chamber between the iris and the lens. The lens is suspended to the ciliary body by the suspensory ligament (Zonule of Zinn), made up of fine transparent fibers. The __vitreous body__ is a clear jelly that is much larger than the aqueous humour present behind the lens, and the rest is bordered by the sclera, zonule, and lens. They are connected via the pupil.
