The Aqueous Humour is located at the front
of each eye in the human body.
Note that this is spelt "Aqueous Humor" in textbooks that
use American spellings - the meaning is the same.
The aqueous humour is a watery fluid that fills the
chamber called the "anterior chamber of the eye" which is located
immediately behind the cornea
and in front of the lens
- click
for diagram, and also the "posterior chamber of the eye"
which is a very narrow compartment located between the peripheral part
of the iris,
the suspensory ligament of the lens, and the ciliary
processes.
The aqueous humour is very slightly alkaline salt solution that includes
tiny quantities of sodium and chloride ions.
It is continually produced, mainly by the capillaries
of the ciliary processes, and drains away into Schlemm's canal, located
at the junction of the cornea and the sclera.
The subject of visual (also known as "physiological") optics
is a key component of many courses within the fields of both biology and
physics. It is also an essential consideration in the design of displays
and control units used in many applications from televisions and mobile
telephones to advanced aircraft. In the context of engineering "visual
optics" is one of several medical and psychological topics in the
important area of "Human Factors". |
