A&P Corbit
| Question | Answer |
|---|---|
| Define cutaneous membrane | skin |
| Mucous membranes secrete what | mucus |
| Mucous membranes lines what | body cavities that are open to the outside |
| Serous membranes secrete what and what is their function | serous fluid, prevent friction |
| Serous membranes line what | cavities that are closed to the outside |
| The Integumentary systems consist of: | skin, hair, nails |
| Functions of the Integumentary system are: | protection, temperature maintenance, synthesis & storage of nutrients, sensory reception, excretion & secretion |
| The integumentary system prevents deeper tissues from: | Mechanical damage-brusing chemical damage - acid and bases bacterial damage - infections Ultraviolet radiation - sunlight thermal damage - heat & cold Desiccation - drying out |
| The integumentary system aids in what that is controlled by the nervous system | heat loss or heat retention |
| the integumentary systems also aids in | excretion of urea and uric acid and synthesizes vitamin D |
| Vitamin D is important in | absorption and metabolism of calicum |
| The outer layer of skin is known as | epidermis |
| The inner layer (underlying) layer of skin is | dermis |
| Define blister | collection of fluid when the epidermis and dermis is separates |
| The subcutaneous tissue is mainly | adipose tissue |
| The epidermis is | a vascular composed of up to 5 layers |
| Most of the cells of the epidermis are what | keratinocytes |
| keratinocytes produce what | keratin (a tough protein) |
| The deepest layer of the epidermis is known as | stratum basale or stratum germinaitivum |
| The outer most layer of the epidermis is the | stratum corneum |
| The stratum corneum is | "replaced" and we get 'new' epidermis every 25-45 days |
| Melanin = | a pigment; increases with exposure to sunlight |
| Merkel cells are what | scattered in the epidermis and are for the sense of touch |
| Herpes Simplex I causes | cold sores (fever blisters) |
| The dermis or corium does what | 'holds' the body together and has good blood and nerve supply |
| Collagen fibers are | strong |
| Elastin fibers do what | stretch and recoil |
| A decrease in what causes wrinkles | Elastin fibers |
| Decubitus ulcer is what | ulcer that appear in pressure areas (bedridden patients), usually found on buttocks |
| To help prevent Decubitus ulcers, do what | position patient every 2 hours; keep dry; nutrition |
| What are the three pigments that contribute to skin color? | melanin, carotene, oxygen |
| Cyanosis = | bluish skin due to decreased oxygen |
| Alternation of skin color may what | notify the health care provider of certain diseases or conditions |
| What are some alternation of skin color | erythema - redness Pallor or blanching - dehydration, low blood pressure or enemea Jaundice - yellow Bruises - blood disorders or abuse |
| Cutaneous glands are what type of gland | exocrine glands that release secretions to the skin surface via ducts |
| Sebaceous glands are | oil glands |
| Where are the sebaceous glands | attached to the hair shaft |
| What is the function of the sebum? | lubricates the hair and skin to inhibit the growth of bacteria |
| Define acne | over activity of the sebaceous glands |
| Define seborrhea | increased discharge of sebaceous matter upon the skin |
| Sudoriferous glands are | sweat glands |
| Eccrine glands produce what | sweat |
| Apocrine glands are located where? | genital and axillary areas |
| Which gland is important in heat regulation of the body | eccrine |
| Which gland is activated during stress or pain? | Apocrine |
| Ceruminous glands are located where? | external ear canel |
| Ceruminous glands secrete what | cerumen |
| Define dehydration | loss of fluids |
| Hair and hair follicles are located within which layer of skin? | dermis |
| What projects from the surface of the scalp or skin? | hair shaft |
| What is the function of the arrector pili muscle? | when contracted it causes goose bumps or the hair to stand up |
| Hair is kept soft and pliable by what type of gland? | sebaceous gland |
| The nail is a modification of which layer of skin | epidermis |
| If the blood flow is decreased, thus oxygen is decreased what color might the skin be | cyanotic |
| Define the Rule of Nines | estimates the percentage of the body that is burned |
| Describe 1st degree burn | red, painful, no blisters, only epidermis is affected |
| Describe 2nd degree burn | red, painful, blistered, may be swollen, damages epidermis and part of the dermis |
| Describe 3rd degree burns | epidermis and dermis is destroyed, may affect underlying bones, tissue and tendons, skin is charred and dry |
| The greatest threat for burn patients is | infection |
| Define tinea pedis | athletes foot |
| A cold sore is caused by | HSV1 virus |
| Define contact dermatitis | inflammatory skin rash that results something that you have come in contact with |
| Define impetigo and is it contagious? | bacterial infection caused by staph, highly contagious; mostly children are affected |
| Define psoriasis | chronic over growth of the epidermis - there is no cure |
| Define verruca and what causes it | warts, virus |
| The sun worshipper's rule for skin cancer is | A- asymmentry B- border irregularity c- color D - diameter (6mm) E - elevation |
| Define Lanugo | downy type of skin seen at 5th or 6th month of gestation |
| Define Vernix caseosa | a cheesy substance that protects the fetus |
| Define Milia | over activity of the sebaceous glands; milk spots on infants |
| Define Alopecia | hair loss |
| In warm environments, arterioles do what | dialate thus increasing blood flow |
| When arterioles dialate what happens | brings excess heat close to the body surface to be radiated to the environment |
| In cold environments, arterioles do what? | constrict thus decreasing blood flow |
| When arterioles constrict what happens | keeps heat within the body |
| Define necrosis | tissue death |
| Define cyanosis | bluish skin color as a result from reduced oxygenation of the blood in superficial vessels |
| What are 2 ways the skin helps get rid of body heat? | radiation from the skin surface and evaporation of sweat |
| What helps the layer beneath the dermis insulate the body | fat in the subcutaneous tissue layer |
| A localized concentration of melanin is | moles or freckles |
| The water proofing protein epidermal cells is called | keratin |
| Wrinkling in the skin is due to loss of the | elastin fibers of the skin |
| A decubitus ulcer results when skill cells are deprived of | oxygen |
