Question | Answer |
functions of the skin | keeps harmful stuff out of the body, retains water and electrolytes, protects internal structures,excretory functions, acts as a gland by synthesizing vitimin d, houses sensory receptors, plays a role in body temp regulation |
skin is called | integument or cutaneous membrane |
2 layers | dermis and epidermis |
thin outer layer composed of stratified squamous, no blood supply, and can be divided in to 5 layers | epidermis |
lies on top of the dermis and has access to rich blood, cells are continuously dividing and pushing old cells to the epithelium | stratum germativum |
hardens thew skin cells and makes the skin water resistant | keratin |
surface layer of the epidermis composed of about 30 layers of dead flat keratinized cells | stratum corneum |
loss of about 500 ml through skin daily, can not be felt | insensible perspiration |
located under the epidermis and is composed of dense fibrous tissue | dermis |
stevens johnsons syndrome is caused by what | an allergy to sulfa drugs |
skin mirrors skin reveals | disease processes in the body, drug reactions, chronic irritation, stress level, what is going on on the inside |
not considered part of the skin, composed primarily of adipose tissue | subcutaneous or hypodermis |
2 roles of subcutaneous tissue | insulates from extreme temp changes anchors the skin to underlying surfaces |
cells that secrete a skin darkening pigment that is located deep with in the epidermal layer of the skin | melanocytes |
strains the surrounding cells causing them to darken | melanin |
occurs when cells fail to produce any melanin | albinism |
loss of melanin in certain areas of the skin | vitiliago |
yellow pigment | carotene |
cyanosis | blue skin |
blushing is caused by | dilation of blood vessels |
ecchymosis | a black or blue area |
the main function of sparse body hair | to sense insects before the bite us |
function of eyelashes and eyebrows | protects eyes from dust and perspiration |
hair growth is influenced by | sex hormones testosterone and estrogen |
excessive hair growth | hirsutism |
head hair is a collection of | dead keratinized cells |
red hair contains | iron |
shape of hair determines the appearance of hair round, oval, flat | straight, wavy, curly |
contraction of this muscle makes hair stand on end | arrector pili |
thin plates of stratified squamous that contain a hardened form of keratin | nails |
each nail has | a root, free edge and nail body |
caused by chronic heart and lung disease, indicates finger tips are receiving a poor oxygen supply | clubbing |
brittle nails are due to | poor oxygenation; nutritional anemia |
also referred to as oil glands found on the areas of the body that have hair | sebaceous glands |
oily substance secreted by sebaceous glands what does it do | sebum helps waterproof hair and skin gradually decreases with age, |
the cream cheese like substance on newborns secreted by sebaceous glands | vernix caseosa |
sweat glands, located on the dermis | sudoriferous glands |
2 types of sweat glands | apocrine and eccrine |
usually found in axillary and genital areas, associated with hair follicles, responds to emotion | apocrine |
in animals the excretions act as sex attractants | pheromones (apocrine) |
vaginal secretions of an ovulation female, cause a peak in testosterone | copuline |
The more numerous and widely distributed of the sweat glands, esp on the forehead neck back upper lip palms and soles | eccrine glands |
sweat secreted by eccrine glands plan and important role in | temp regulation |
found in external and auditory canal of ear | cerminous glands |
earwax | cerumen |
exocrine glans and maximally secrete how much per hour | one gallon |
temp is lowest in | am |
inner body parts tell | core temp |
skin and mouth tell | shell temp |
body temp is maintained by balancing heat loss and heat production this is called | thermoregulation |
heat is thermal energy and is produced by | millions of chemical reactions with in the body |
80% of heat loss occurs through20% through | the skin, respiratory and excretory processes |
4 means of heat loss | Radiation, conduction, convection, and evaporation |
the amount of heat that can be lost is influenced by | the amount of blood in the dermal blood vessels |
heat is lost from a warm object to the surrounding cooler air | radiation |
loss of heat from a warm body to a cooler object in contact with the warm object | conduction |
loss of heat by air currents moving over the surface of the skin | convection |
occurs when a liquid becomes gas | evaporation |
water can not be evaporated from the skin | on a humid day |
the thermostat of the body, located in the brain | hypothalamus |
hypothalamus senses | changes in body temperature and sends info to the skin and skeletal muscles |
dilate with temperature elevation | blood vessels |
heat syncope | fainting |
most serious of heat stress, failure of the thermoreglatory mechanisms | heat stroke |
a baby can not------ because it has only one layer of subcutaneous fat | shiver |
generated more heat then the metabolisms of regular adipose tissue | brown adipose tissue |
burns are classified according to | the depth and extent of the area burned |
burns that are red painful and slightly swollen only epidermis is involved | 1st degree |
burns involve both epidermis and dermis, little damage to dermis, redness, pain, edema, and blisters | 2nd degree |
burn in which epidermis and dermis are both destroyed, painless because the sensory receptors have been destroyed | 3rd degree or full thickness |
burn injury is evaluated according to the | rule of 9 |
dead burned tissue that forms thick, scab like layer over the burned surface | eschar |
can cut of blood supply to extremities, if it is around the chest it can prevent chest expansion and breathing, also secrets toxins in to blood | eschar |
eschar is slit in a checkerboard pattern to facilitate expansion | escharotomy |
