Senses: TOUCH

The skin is the organ of touch. It is the largest organ. We use our skin to identify if something is hot or cold (temperature), hard or soft, smooth or rough (texture).

Our body is covered in skin which has nerve endings that pick up information and send it to the brain.

In some parts of our skin we have more nerve endings so they are more sensitive like the palms of our hands or the soles of our feet.

The skin is made up of three layers:

The epidermis: Melanin is here.

The dermis: Nerve endings, blood vessels and sweat glands are here.

The subcutaneous layer: Hair follicle and fat are here.
