INTEGUMENTARY SYSTEM

 

Question Answer
(1) Cover and protects the body, (2) Regulate Body Temperature, (3) Excretes Wastes, (4) Reduces water loss, (5) Houses sensory receptors5 FUNCTIONS of INTEGUMENTARY SYSTEM
Cover and protects the bodyProtects us from Pathogens, Injury & UV radiation
(1)Sweating, (2) Dilate/constrict of blood vessels, (3) Goosebumps3 ways to regulate temperature
Skin constricts to get closer to the body (to maintain body temperatureWHEN COLD Skin _________
Skin does not constrictWHEN HOT Skin _________
Urea as sweatis the waste excreted
Epidermis & Dermis2 MAIN LAYERS OF SKIN
Epidermisouter (surface) layers of skin
Epidermis10-30 cells thick
(1) Inner & (2) OuterTwo parts of Epidermis
EPIDERMIS - Inner layerIn the lowest layer, cells reproduce and push older cells toward the surface (Basale region)
EPIDERMIS - Inner layerAs the cells near the surface, they flatten and their organelles disintegrate (Granulosum)
EPIDERMIS - Inner layerProduction of keratins (spinosum)
EPIDERMIS - Inner layerThis replaces cytoplasm
EPIDERMIS - Outer layerThe Keratin producing cells die as they move toward the surface
EPIDERMIS - Outer layerOuter dead layer waterproofs and protects inner layers
EPIDERMIS - Outer layerIt is shed continually and is completely replaced in 2-4 weeks

Melanin, Carotene & Hemoglobin3 TYPES OF SKIN PIGMENT
Melanocytescells that produce melanin
Melanindark brown pigment
MelaninProduced at the base of the epidermis
Melaninimportant for proper functioning of photoreceptors
MelaninGives skin its color
MelaninProtects skin from UV radiation
CaroteneYellow to Orange pigment
Carotenefrom carrots and yellow vegies
CaroteneNot easily noticeable unless large amounts are consumed
Blood (Hemoglobin)pink to red pigment
Blood (Hemoglobin)Shade depends on dilation of vessels
Blood (Hemoglobin)Continued constriction may lead to Cyanosis
Cyanosisa bluish discoloration of the skin resulting from poor circulation or inadequate oxygenation of the blood.
(1) Eumelanin, (2) Phaeomelanin2 types of MELANIN

Sebaceous glandssecrete oily sebum to soften and waterproof skin
Nailsprotective covers of end of fingers and toes

Sweat glandsRegulate heat
Sweat glandsProduces ear wax
Sweat glandsProduces milk during lactation
Blood vesselsto nourish skin cells
Nervesto send and receive messages
Erector Pilli Musclesmooth muscles that causes goosebumps
Erector Pilli MuscleCauses hair to stand erect
SUBCUTANEOUS LAYERConnective tissue
SUBCUTANEOUS LAYERAnchors dermis to the body
SUBCUTANEOUS LAYERContains fat cells to protect and cushion
Acneinfection of sebaceous glands
Benign tumorfleshy growths on neck, armpits and body. This is harmless
Vascular BirthmarksBlood vessel abnormality affecting 0.5% of population that darkens skin
