Touch - Sensory Receptors

The video explains how our sense of touch allows us to perceive different sensations like softness, prickliness, cold, and heat. It describes how special cells in our skin, called receptors, detect these sensations and send messages to our brain, which interprets them. An example is given with snow, explaining how receptors in the skin detect cold and communicate this to the brain.

• Via electrical signals

• By releasing hormones
