The Vitreous Body is another term for the
Vitreous
Humour.
The Vitreous Body (or Vitreous
Humour) is located in the the large area that occupies approx.
80% of each eye in the human body. Note
that this is spelt "Vitreous Humor" in textbooks
that use American spellings - the meaning is the same.
The vitreous body is a perfectly transparent
thin-jelly-like substance that fills the chamber behind the lens of
the eye - click
for diagram. It is an albuminous fluid enclosed in a delicate transparent
membrane called the hyaloid
membrane.
There is a canal called the canal of Stilling running
through the centre of the vitreous body from the
entrance of the optic nerve to the posterior surface of the lens. This
is filled
with fluid and lined by a prolongation of the hyaloid membrane.
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".
