7. Integumentary System and Body
| Question | Answer |
|---|---|
| The skin, accesory structures and the subcutaneous tissue make up this system | Integumentary System |
| The skin can be called these two things | Integument or Cutaneous membrane |
| The outer or surface layer of the skin | Epidermis |
| The inner layer of the skin | Dermis |
| The study of skin and skin disorders | Dermatology |
| This layer of the epidermis that lies on top of the dermis and makes new cells | Stratum Germinativum |
| The tough protein made by epidermal cells as they near the surface of the skin | Keratin |
| The surface layer of epidermal cells is called _________ | Stratum Corneum |
| The 500ml/day of water that is lost through the skin each day is called ___________ | Insensible Perspiration |
| The layer under the dermis which is not considered part of the skin is called the _________ | subcutaneous layer or hypodermis |
| Cells deep within the skin that secrete melanin are called ___________ | Melanocytes |
| The skin darkening pigment | Melanin |
| This is the name of the disorder that occurs when the melanocytes completely fail to secrete melanin | Albinism |
| The name of a disorder where there is partial loss of melanin in patches of skin | Vitiligo |
| A yellow pigment of the skin | Carotene |
| A coloration of the skin related to a lack of oxygen | Cyanosis |
| A condition that causes the skin to turn yellow due to lack of bilirubin excretion by the liver | Jaundice |
| These two hormones influence the growth of hair in the axillary and pubic areas | Testosterone and Estrogen |
| The loss of hair is called this | Alopecia |
| Oil glands of the skin are also called ____________ | Sebaceous Glands |
| The oily substance secreted by sebaceous glands is called ______ | Sebum |
| The sebaceous gland secretion that covers babies when they are born | Vernix caseosa |
| Also called sudoriferous glands, these glands secrete liquid onto the skin | Sweat glands |
| This type of sweat gland is associated with hair follicles and are found in the axillary and genital areas | Apocrine glands |
| These sweat glands are the most numerous and located throughout the body. They are not associated with hair follicles | Eccrine glands |
| These modified sweat glands are found in the external auditory canal of the ear | Ceruminous glands |
| This secretion of the ceruminous glands is also called ear wax | Cerumen |
| A temperature taken from the inner parts of the body is called a ______ temperature. | Core |
| Temperatures taken from the surface areas of the body are called ______ temperatures | Shell |
| The mechanism whereby the body balances heat production and heat loss is called _________ | Thermoregulation |
| Heat is lost from a warm object (the body) to the cooler air surrounding the warm object. Ex. a person losing heat to a cooler room | Radiation |
| Heat lost from a warm body to a cooler object in contact with the warm body. Ex. sitting on a block of ice | Conduction |
| Loss of heat by air currents moving over the surface of the skin | Convection |
| Loss of heat when liquid on skin becomes a gas | Evaporation |
| Area of brain that controls body temperature | Hypothalamus |
| A process in which brown addipose tissue is metabolized in a neonate to increase body temperature | Nonshivering thermogenesis |
| A burn that involves only the epidermis | First–degree burn |
| A burn that involves both epidermis and some of the dermis | Second–degree burn |
| A burn that involves all of the epidermis, dermis, and possibly the underlying tissue | Third–degree burn |
| A system that is used to estimate percentage of body surface area burned | Rule of Nines |
| Dead burned tissue that forms a thick, inflexible, scablike layer over the burned surface | Eschar |
| A disorder of the skin in which sebaceous glands oversecrete sebum. | Acne |
| A fungal infection of the skin that affects the webs of the toes, skin of the feet | Athlete's foot |
| A localized collection of pus caused by staphylococcal infection of hair follicles and sebaceous glands | Boil |
| Watery vesicles due to infection with the herpes simplex virus | Cold sore |
| Saclike structure containing fluid or semisolid material with a strong capsule | Cyst |
| Nonspecific inflammation of the skin with erythema, papules, vesicles, scabs or crusts | Dermatitis |
| Inflammatory condition characterized by redness, papular and vesicular lesions, crusts, and scales of the skin | Eczema |
| Red raised patches (wheals) with intense itching often due to allergic reaction | Hives |
| A contagious infection of the skin usually due to staphylococcus bacteria | Impetigo |
| A chronic skin condition characterized by lesions that are red, dry, elevated, and covered by silvery scales | Psoriasis |
| Most agressive form of skin cancer | Malignant melanoma |
