Skin, primary functions intact skin 1st line of immune defense, waterproofs body & is major receptor for sense of touch.
sebaceous glands, primary functions secrete sebum (oil) to lubricate the skin & discourage the growth of bacteria on the skin
sweat glands, primary functions secrete sweat to regulate body temp & water content & excrete some metabolic waste
hair, primary functions aids in controlling the loss of body heat
nails, primary functions protect the dorsal surface of the last bone of each finger & toe
integumentary system consists of... skin & related structures
integumentary system does this... performs important functions in maintaining the health of the body
skin is major receptor for... sense of touch
skin helps body synthesize vitamin D, which is an essential nutrient, from sun's ultraviolet light, while screening out some harmful UV radiation
vitamin D an essential nutrient, from the sun's ultraviolet light.
avg amount of skin on an adult 2 square yards, which makes it the largest bodily organ.
"related structures" of the integumentary system sebaceous glands, sweat glands, hair, and nails
3 layers of skin epidermis, dermis, subcutaneous
cutaneous pertaining to the skin
epidermis outermost layer of skin, made up of several specialized epithelial tissues. Does not contain any blood vessels or connective tissue
epithelial tissue forms a protective covering for all internal & external surfaces of the body
squamous epithelial tissue forms upper layer of epidermis that consists of flat, scaly cells that are continuously shed
squamous scale-like
basal layer lowest layer of epidermis where new cells are produced & pushed upward. When cells reach surface, they die and become filled w/ keratin
keratin fibrous, water-repellent protein.
soft keratin primary component of epidermis
hard keratin found in hair & nails
melanocytes special cells that are also found in the basal cell layer. Produce & contain a dark brown to black pigment known as melanin.
melanin pigment that determines color of skin, which depends on type & amount of pigment that is present. Produces spots of color such as freckles & age spots, protects against some UV rays
ultraviolet UV, light that is beyond the visible spectrum @ the violet end. Some help skin produce vit D, others damage skin.
dermis aka corium; thick layer of living tissue directly below the epidermis. Contains connective tissue, blood & lymph vessels, & nerve fibers.
Related structures of the integumentary system found in the dermis hair follicles, sebaceous glands, & sweat glands
sensory nerve endings in the dermis sensory receptors for stimuli such as touch, temperature, pain, & pressure
collagen in the dermis means glue; tough yet flexible fibrous protein material found in the skin & also in bones, cartilage, tendons, & ligaments
mast cells found in connective tissue of dermis, respond to injury, infection, or allergy by producing & releasing substances, including heparin & histamine
heparin released in response to an injury, is an anticoagulant.
anticoagulant prevents blood clotting
histamine released in response to allergens, causes the signs of an allergic reaction response, including itching & increased mucus secretion
subcutaneous layer located just below the layers of skin & connects the skin to the surface muscles. Made up of loose connective tissue
adipose fat
cellulite term used to describe deposits of dimpled fat around the buttocks & thighs. Ordinary fatty tissue.
lipocytes aka fat cells; predominant in subcutaneous layer where they manufacture & store large qty's of fat
sebaceous glands located in dermis layer of skin & are closely associated w/ hair follicles
sebum sebaceous glands secrete this. Oily substance released through ducts opening into hair follicles. Then moves onto surface & lubricates skin.
because sebum is slightly acidic, it discourages the growth of... bacteria on skin
sweat glands aka sudoriferous glands; tiny coiled glands found on almost all body surfaces.
2 types of sweat glands apocrine glands (in hair follicles) and eccrine glands (open onto the skin & are most numerous in palms of hands, soles of feet, forehead.
pores openings on the surface of the skin that act as the ducts of the sweat glands
perspiration commonly known as sweat; secreted by sweat glands & is made up of 99% water plus some salt & metabolic waste products.
how much liquid is perspired daily up to 1 quart
as perspiration evaporates into the air... it also cools the body
body odor associated w/ perspiration... comes from the interaction of sweat w/ bacteria on the skin's surface
hidrosis production & excretion of perspiration
mammary glands produce milk & are modified sweat glands, sometimes classified w/ integumentary system. Also part of reproductive system
hair fibers are rod-like structures composed of tightly fused, dead protein cells filled w/ hard keratin. Darkness & color of hair determined by amt & type of melanin produced by melanocytes that surround core of hair shaft
hair follicles sacs that hold the root of the hair fibers. Shape of follicle determines whether hair is straight or curly.
although hair is dead tissue... it appears to grow b/c cells @ base of follicle divide rapidly & push old cells upward. As cells pushed upward, harden & undergo pigmentation
arrector pili tiny muscle fibers attached to the hair follicles that cause the hair to stand erect. In cold or fright, muscles contract, causing raised areas of skin - goose bumps.
what is the reasoning behind goose bumps? action reduces heat loss through the skin

part of a nail body, bed, free edge, lunula, cuticle, nail root
nail body translucent & is closely molded to the surface of the underlying tissues. Made up of hard, keratinized plates of epidermal cells
nail bed joins nail body to the underlying connective tissue, nourishes the nail. BV's here give nail its pink color
free edge of nail portion of the nail not attached to the nail bed, extends beyond the tip of the finger/toe
nail lunula pale half-moon-shaped region at every nail root, generally most easily seen in thumbnail. Active area of nail, where new keratin cells form
-ula little
