Without the information we receive through our five senses we could not

function as the beings we are. Each sense is important in its own right,

but each has limitations. On the other hand, one sense can be used to

compensate for another. The most effective way to receive information,

of course, is to use all our senses in harmony.

Cornea - the clear, dome-shaped tissue covering the front of the eye.

Eyebrow - a patch of dense hair located above the eye.

Eyelash - one of the many hairs on the edge of the eyelids.

Eyelid - the flap of skin that can cover and protect the eye.

Iris - the colored part of the eye - it controls the amount of light that enters the eye by

changing the size of the pupil.

Lens - a crystalline structure located just behind the iris - it focuses light onto the retina.

Optic nerve - the nerve that transmits electrical impulses from the retina to the brain.

Pupil - the opening in the center of the iris- it changes size as the amount of light changes

(the more light, the smaller the hole).

Retina - sensory tissue that lines the back of the eye. It contains millions of photoreceptors

(rods and cones) that convert light rays into electrical impulses that are relayed to the brain

via the optic nerve.

Tear- clear, salty liquid that is produced by glands in the eyes.

Vitreous - a thick, transparent liquid that fills the center of the eye - it is mostly water andgives the eye its form and shape (also called the vitreous humor).

blood vessels - Tubes that carry blood as it circulates. Arteries bring

oxygenated blood from the heart and lungs; veins return oxygen-

depleted blood back to the heart and lungs.

dermis - (also called the cutis) the layer of the skin just beneath the

epidermis.

epidermis - the outer layer of the skin.

hair follicle - a tube-shaped sheath that surrounds the part of the hair

that is under the skin. It is located in the epidermis and the dermis. The

hair is nourished by the follicle at its base (this is also where the hair

grows).

hair shaft - The part of the hair that is above the skin.

hair erector muscle - a muscle is connected to each hair follicle and the

skin - it contracts (in response to cold, fear, etc.), resulting in an erect

melanocyte - a cell in the epidermis that produces melanin (a dark-

colored pigment that protects the skin from sunlight).

Pacinian corpuscle - nerve receptors that respond to pressure and

vibration; they are oval capsules of sensory nerve fibers located in the

subcutaneous fatty tissue

sebaceous gland - a small, sack-shaped gland that releases oily (fatty)

liquids onto the hair follicle (the oil lubricated and softens the skin).

These glands are located in the dermis, usually next to hair follicles.

sweat gland - (also called sudoriferous gland) a tube-shaped gland that

produces perspiration (sweat). The gland is located in the epidermis; it

releases sweat onto the skin.

subcutaneous tissue - fatty tissue located under the dermis.
