Question

Draw a diagram of the human eye as seen in a vertical section and label the parts which suits the following descriptions relating to the-
i) Photosensitive layer of the eye
ii) Structure which is responsible for holding the eye lens in its position
iii) Structure which maintains the shape of the eyeball and the area of no vision
iv) Anterior chamber seen in front of the eye lens
v) Outermost transparent layer seen in front of the eyeball

Answer 1

Hint: The human eye is an organ that helps in vision. They consist of photosensitive cells that can detect visible light and convey the information to the brain.

Complete answer:
Humans are known to possess two eyes that are situated on the left and right of the face on boy cavities known as orbits. The front of the eye is made up of sclera which is whitish , iris which is colored and pupil. A thin layer known as the conjunctiva sits on this and together this front part is known as the anterior part of the eye. The front part also contains cornea which is transparent and curved as well as the eye lens, the space between cornea and lens is filled with aqueous humor. The posterior chamber is filled with vitreous humor and consists of the retina. The retina comprises the photosensitive cells which upon receiving light convert them into electrical signals which are carried by the optic nerve to the brain and interpreted as vision.

According to the question the following parts are-
i) Photosensitive layer of the eye-retina
ii) Structure which is responsible for holding the eye lens in its position-suspensory ligaments
iii) Structure which maintains the shape of the eyeball and the area of no vision-blind spot
iv) Anterior chamber seen in front of the eye lens-aqueous humor
v) Outermost transparent layer seen in front of the eyeball-conjunctiva

Note: The human eye is one of the most important organs of the body and any problem found to be associated with it, such as eye irritation or any eye disease must be immediately consulted with an eye care specialist. Retina is the main layer responsible for vision.
