Question

Identify the parts ‘a’ ‘b’ and ‘c’ in the figure below.

• A. a- sclera, b-choroid, c- retina
• B. a- retina, b-choroid, c- Sclera
• C. a- sclera, b-retina, c- choroid
• D. a- choroid, b-retina, c- sclera

Answer 1

The correct option is B a- retina, b-choroid, c- Sclera

In the given figure ‘a’ is retina, ‘b’ is choroid and ‘c’ is sclera.
The sclera is the outer layer of the eye. It is known as the white of the eye and is composed of dense connective tissue including elastic and collagen fibres. Its anterior portion is called cornea.
The choroid is the middle layer of the eye. It looks bluish in colour and contains many blood vessels.
The retina is the inner layer of the eye. It contains three layers of cells from outside to inside: photoreceptor cells, bipolar cells and ganglion cells. It is the site at which an image is formed in the eye. It receives the light and converts it into neural impulses. It transmits these neural impulses to the brain for visual recognition.
