Skin and touch

The skin is the sense organ of touch. It detects temperature, pain, pressure, etc. The skin is composed of hair, pore, sweat gland, touch receptors, and nerves. The epidermis is waterproof and serves as a protective wrap for the underlying skin layers and the rest of the body. It contains melanin, which protects against the sun's harmful rays and also gives skin its color. When you are in the sun, the melanin builds up to increase its protective properties, which also causes the skin to darken. The epidermis also contains very sensitive cells called touch receptors that give the brain a variety of information about the environment the body is in. Pores are on the surface of the skin which allows the hair to grow. The hair protects us from the sun and the cold. The second layer of skin is the dermis. The dermis contains hair follicles, sweat glands, blood vessels, nerve endings, and a variety of touch receptors. Sweat glands eliminate waste produced at the dermis level of the skin by opening their pores at the surface of the epidermis and releasing the waste. The bottom layer is the subcutaneous tissue which is composed of nerves. The information captured by receptors in the skin travels to the brain through the nerves. The brain receives and interprets this information.

However, all of this is different for aliens. The skin is the sense organ of hearing. Their soft skin detects sounds and their properties, and where these sounds come from. Because the skin is around all their body, they can detect sounds from far distances, even if they are just whispers. Therefore, this is their most powerful sense organ. The hairlus remain still as guitar sting when they feel the noise, so they can detect it easily. Poaires are on the surface of the skin, which allows the hair to grow. Sweit glennd clean the skin with a special oil in order to make the sound clearer. Then, the information captured by receptors in the skin travels to the brain through the nerves. The brain receives and interprets this information.
