Control: When body temp. rises your blood vessels allow heat escape the skins surface through sweat glands. If your body temp. drops the blood vessels in the skin constrict reducing amount of heat lost and helps maintain the body heat. #3:Sensation: Nerve cells in dermis act as receptors that are stimulated by changes in outside environment.

12 Lesson 3: Healthy Eyes & Ears Vocabularysclera: It’s the white part of the eye, its made up of tough, fibrous tissues that protect the inner layers of the eye and supports the shape of the eyeball.Cornea: It’s a transparent tissue that bends and focuses light before it enters the lens.Retina: The inner layer of the eye wallAuditory ossicles: Three small bones linked together that connect the eardrum to the inner ear.Labyrinth: consists of a network of curved passages that can be divided into three partsTinnitus: A condition in which a ringing, buzzing, whistling, roaring, hissing or other sounds are heard in the ear in absence of external hearing.
