Question

The vitreous humour, a jelly like substance is found in the posterior part of
(a) Eye
(b) Ear
(c) Nose
(d) Heart

Answer 1

Hint:It is a clear gel like part, that occupies the space right behind the lens and before the retina at the back of the eye.
It contributes very less to the optical power of the eye but mainly has a role in maintaining the structural stability of the eye.

Complete answer:The human eye is divided into three sections:
the anterior chamber, the vitreous chamber and lastly the posterior chamber.

The vitreous chamber is positioned just at the back of the eyeball. It is the largest of all the three chambers and takes up around 75% of the eye.
The vitreous humour (also known simply as the vitreous) is a clear, colorless fluid that fills the space between the lens and the retina of the eye and 99% of it consists of water and the rest content is basically a mixture of collagen, proteins, salts and sugars.
Despite the water-to-collagen ratio, it has a characteristic firm jelly-like consistency.
The vitreous humour performs a crucial role in protecting your eye.
Most significantly, it helps in holding its typical spherical shape.
It also comes in contact with the retina. The pressure of the vitreous humour helps to keep the retina stable and in place.

So, the correct answer is ‘Eye’

Note:With age, the vitreous humour liquefies and shrinks. Portions of its mixture of collagen and proteins start to become ‘stringy’.
These are better known as ‘floaters’.
These can be identified as specks, strings or other shapes just out of the corner of your eye. If this shrinkage causes a section of the fibers to pull away all at once, it is called a vitreous detachment.
