7. Integumentary System and Body

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
