Introduction To Sense Organs

We have all heard about the five senses i.e see, hear, smell, taste. and touch. To see we use our eyes, to hear we use our ears, to smell we use our nose, to taste we use our tongue, and we touch with the help of tongue. So basically, human beings have five sense organs i.e. eyes, ear, nose, tongue, and skin.

Sense Organs

 Eyes (Sense of Sight)

Eyes

A good sense of sight is achieved by healthy eyes. Eyes are the organs of the visual system. Eyes provide vision and the sense of sight to human beings, animals, birds, fishes, etc. Human beings can have various eye colors depending on the amount of melanin present in one’s body. The eye color can vary from brown to blue. However, eyes are sensitive to light.

Nose (Sense of Smell)

Nose

The organ for the sense of smell is the nose.  Nose has nostrils, we breathe in through nostrils. The olfactory system is responsible for our sense of smell and the nose is also known as an olfactory organ. Usually, animals have a stronger sense of smell than human beings. However, human beings can also smell thousands of various odors and fragrances. The nose is also an organ which helps us in the sense of taste. For example, we can smell a gas leak.

Ears (Sense of Hearing)

Ear

The organ for the sense of hearing is ears. Hearing or auditory perception is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. For example, we hear music through earphones which are inserted into our ears. Total or partial ability to hear is known as hearing loss.

Sense of Touch, Smell, and Taste

Skin (Sense of Touch)

Touch

The organ for the sense of touch is skin. Skin is the largest organ as it is located throughout the human body. Various receptors are used for different situations like pain, temperature, pressure, etc. For example, when we touch something hot like a hot cup of tea or coffee, we instantly move our hands away from it.

Tongue (Sense of Tasting)

The organ for the sense of taste is the tongue. The tongue has various receptors which can detect whether the item consumed is salty, sweet, bitter or sour.  The behind part of the tongue detects bitter taste, the frontmost part detects salty taste, the side part detects sour taste and the middle and front part detects sweet taste.
