Question

Which alphabet is a part of our body?

Answer 1

Hint: When we think of this question, we should start by dictating every alphabet in our mind and that’s how we will be able to catch the right answer. To make it even easier it’s among the upper body parts of our body and makes us familiar with the beauty around us.

Complete answer –
It is quite an interesting answer to begin with. So, the alphabet about which you all have been curious is ‘I’ i.e. our eye.
As we all know, the eye is an important and delicate structure. The orbits, bony structures in the skull, protect the eyes from physical damage and a pad of fat behind the eyeball helps to cushion it from shocks. Each eye weighs around 7 grams.
The eye is made up of three layers – sclera, choroids and retina.
Sclera – It is mesodermal in origin, white in color and so called the white of eye. Its outermost layer is tough but the elastic sheath of fibrous connective tissue contains collagen fibers.
Its anterior portion is called the cornea and lies over the colored part of the eye, the iris.
Choroid - It is the vascular part that lies below sclera. It nourishes the retina. It forms a ciliary body. It contains many blood vessels and a large amount of pigment. Its anterior portion is modified into three separate structures – the ciliary body, the suspensory ligament and the iris.
Retina – It is the innermost coat of the eyeball. Pigmented epithelial cells form the layer of the retina next to the choroids coat. Three layers make up the major portion – photoreceptor neurons, bipolar neurons and ganglion neurons.

Note –
Each eye is covered with two muscular eyelids for the protection of it.
One more transparent membrane is present in the eye called nictitating membrane or third eyelid.
Any defect in one eye of the eyelid muscles causes squint eyes or strabismus.
