FAQs on Human Sense Organs
| 1. What are the five sense organs in humans and what do they do? |  |
Ans. The five sense organs are eyes (sight), ears (hearing), nose (smell), tongue (taste), and skin (touch). Each sense organ contains special cells that detect stimuli from the environment and send messages to the brain, helping us understand and respond to the world around us. These sensory receptors work together to keep us safe and aware.
| 2. How does the eye help us see things in Class 1 EVS? | |
Ans. The eye is the sense organ responsible for vision, allowing humans to see colours, shapes, and objects. Light enters through the cornea and lens, focusing images onto the retina at the back of the eye. The retina sends signals to the brain, which interprets them as pictures we recognise and understand.
| 3. Why do our ears help us hear sounds differently? | |
Ans. The ear captures sound waves through the outer ear and transmits them via the middle ear bones to the inner ear. The cochlea converts these vibrations into electrical signals that travel to the brain along the auditory nerve. Different frequencies create different pitches, allowing us to distinguish loud from soft sounds and recognise various noises.
| 4. What happens when we taste food using our tongue? | |
Ans. The tongue contains thousands of taste buds-tiny sensory organs on its surface-that detect four basic tastes: sweet, salty, sour, and bitter. Taste receptors send chemical signals to the brain, which interprets the flavour. Combined with smell, taste helps identify food and protect us from harmful substances.
| 5. How does skin act as a sense organ for touch and temperature? | |
Ans. Skin is the largest sense organ, containing touch receptors that detect pressure, pain, temperature, and texture. Different nerve endings respond to heat, cold, and physical contact, sending signals to the brain. This sensory feedback protects the body from injury and helps us interact safely with our environment.
