How do touch receptors in our fingers allow us to differentiate between shapes and textures?
The skin on our fingers acts as a sensor, allowing us to differentiate between smoothness, roughness, and other textures. The greater population of touch receptors in our hand provides greater sensitivity, helping us identify shapes and discern detailed patterns, such as Braille letters. These delicate tasks are possible primarily due to the high number of receptors contained in our fingertips, making them far more sensitive than other parts of our body.
