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". |
