Compare the structures and functions of the epidermis and the dermis.
epidermis: layers of dead, flattened cells covering layers of live cells that continually divide. Its function: protection; dermis: thicker layer, contains blood vessels, nerves, nerve endings, hair follicles, glands. Its functions: detects external stimuli, produces sweat, hair, and oil
Identify and interpret the functions of the integumentary system.
covers the body, detects external stimuli, temperature regulation, produces oil to prevent drying out, hair for protection and insulation
Compare how the skin interrelates with other organ systems to maintain a constant body temperature.
Skin nerve endings detect stimuli and signal the nervous system, which stimulates other body systems in response
How does the skin respond to external stimuli?
External nerve endings in skin detect temperature, pressure, and pain; nerve endings relay information to the brain for a response.
How could third-degree burns over a significant portion of the skin affect the body as a whole?
The body is susceptible to infection and drying out; if enough skin is damaged, it can become life-threatening
Outline steps that occur as a cut in the skin heals.
A blood clot forms. Blood vessels dilate and infection-fighting white blood cells rush to the wound. Epidermal cells divide to fill in the wound (scab). Scab falls off to reveal new skin.
in humans and some other animals, the outermost protective layer composed of an outer layer of dead cells and an inner layer of living cells.
epidermis
protein found in the exterior portion of the epidermis that helps protect living cells in the interior epidermis.
keratin
pigment found in cells of the interior layer of the epidermis; protects cells from solar-radiation damage.
melanin
inner, thicker portion of the skin that contains structures such as blood vessels, nerves, nerve endings, hair follicles, sweat glands, and oil glands.
dermis
narrow cavities in the dermis from which hair grows.
hair follicle
