I WONDER - Why Are Our Fingertips So Sensitive?

The video explains how touch receptors in our fingers, packed with nerve endings, help us sense different textures, temperatures, and pressures. This high concentration of nerve endings allows for a precise sense of touch, enabling delicate tasks such as picking up small objects, feeling fabric textures, and reading Braille.

• To improve vision

Why do fingers have a precise sense of touch?

• Due to their ability to move quickly

• Because they are always exposed

• Because they are larger than other body parts

• Due to the high concentration of nerve endings

Which of the following tasks is enabled by the precise sense of touch?

• Running

• Jumping

• Listening to music

• Picking up small objects

How does the sense of touch help in interacting with the environment?

• By making us run faster

• By improving our sense of smell

• By enabling us to feel textures and explore
