Unit 3.1 Basic Concepts:
Integumentary System = The skin
Roots for skin: cutaneo/dermo
Outermost layer that is visible = epidermis
Describe the epidermis: Made of large cells that look like scales of a fish under the microscope
Scaly apperance = Squamous
Deeper layer under epidermis = dermis
Dermis Charteristics:
Thicker than the epidermis,
Fewer cells
More thick fibers to give skin strength and flexablity
Home to hair follicles, nerves and glands
Hair follicles:
Definition: Root of ur hair
Roots: pilo/tricho
Purpose: Follicles anchor the hair to the skin and provide nerves in ur skin make it the largest sensory organ in ur body
2 types of glands: Sweat and sebacous gland
Sweat glands:
Roots: hidro
Purpose: relases sweat to RID body waste AND cool the body
Sebaceous glands:
Roots: sebaceo
Purpose: Secrete oil as a natural noisturizer for skin and hair
Roots:
Fat = adip / o, lip / o, steat / o
Skin = cutane/ o, /derm/ o, / dermat/o
Hair = pil/ o, trich/o
Sweat = hidr/o
Scale = squam/o
Nail = onych/o, ungu/o
Oil = seb/o, sebace/o
Hidden = crypt/o
Hard, horny = kerat/o
Dry = xer/o
Yellow = xanth/o
Red = erythr/o
white = leuk/o, alb/o
black = melan/o
Unit 3.2 Patient History, Problems and Complaints
Common reason to seek medical attention relating to skin = rash
Painful = dermatalgia/ dermatondiyna
Itchy = pruritus
Hives = urticaria
Oily secretion = seborrhea
Very dry = xerosis
Very wet = macerate
Too much sweat = hyperhidrosis
Not enough sweat = anhidrosis
Loss of pigment = depigmentation
Darkening of the skin = hypermelanosis
Albinism = lack pigment
Hair follicles = embedded in the skin
Hypertrichosis = hair problem is too much
abrasion = scraping away of skin
ab / rasion
albinism = lack of pigment in skin causing patient to look white
albin/ ism
albino = person afflicted with albinism
albino
alopecia = baldness
Greek for fox
anhidrosis = lack of sweating
an/hidr/osis
comedo = a hair follicle that is plugged with sebum(black heads)
Latin for to eat up
cyanhidrosis = blue sweat
cyan/hydr/osis
depigmentation = loss of pigmenitation
de/pigment/ation
dermatalgia = skin pain
dermat / algia
dermatodynia = skin pain
dermato/ dynia
dermatolysis = loose skin
dermato/lysis
erythema = redness
erythroderma = red skin
erythro/ derma
hemathidrosis = sweating blood
hemat / hidr / osis
hisropoiesis = formation of sweat
hidro / poiesis
hyperhidrosis = excessive sweating
hyper/ hidr / osis
hyperkerotosis = excessive growth of horny skin
hyper/ kerat/ osis
hypermelanosis = excessive melanin in the skin
hyper/ melan / osis
hyperpigmentation = excessive sweating in the skin
hyp/hidr/osis
hypomelanosis = diminished melanin in the skin
hyp/ melan/ osis
hypopigmentation = diminsed pigment in the skin
hypo/ pigment/ ation
leukoderma = white skin
leuko / derma
macerate = to soften the skin
Latin for make soft
onychophagia = eating or biting the nails
onycho / phagia
pruritus = an itch (Latin)
rhytidermia = wrinkled skin
rhyti/dermia
sebopoiesis = formation of oil
sebo/ poiesis
seborrhea = discharge of oil (sebum)
sebo / rrhea
trichomegaly = abnormmally thick hair
tricho/megaly
urticaria = swollen raised itchy areas of the skin
Latin for burning nettle
xanthoderma =. yellow skin
xantho / derma
xeroderma = dry skin
xero/ derma
xerosis = condition of dryness
xer/ osis
Unit 3.3 Observation and Discovery
Descriptions relate to the location, size, color, texture and filling or the rash or its pustules. Describes if rash is flat or raised
