blood vessels – red melanocyte - orange

hair erector muscle – blue subcutaneous layer – yellow

II. Identify the following.

________________________________ 1. fatty tissue located under the dermis

________________________________ 2. the outer layer of the skin

________________________________ 3. a tube-shaped gland that produces

perspiration

________________________________ 4. the layer of the skin just beneath the epidermis

________________________________ 5. tubes that carry blood as it circulates

________________________________ 6. a muscle is connected to each hair follicle and

the skin - it contracts (in response to cold,

fear, etc.), resulting in a "goosebump."

(fatty) liquids onto the hair follicle

________________________________ 8. a tube-shaped sheath that surrounds the part

of the hair that is under the skin.

________________________________ 9. nerve receptors that respond to pressure and

vibration; they are oval capsules of sensory

nerve fibers
