A&P CHAPTER 6: INTEGUMENTARY SYSTEM Flashcards
TWO LAYERS OF SKIN
EPIDERMIS (OUTER LAYER)
DERMIS (INNER LAYER)
SUBCUTANEOUS LAYER
BELOW THE DERMIS
BINDS SKIN TO DERMIS
KERATINOCYTES
CELLS THAT MOVE TOWARD SKIN SURFACE, RECEIVE FEWER NUTRIENTS, AND DIE
HARDEN WITH AGE
LAYERS OF EPIDERMIS
INNER TO OUTER:
BASALE
SPINOSUM
GRANULOSUM
LUCIDUM
CORNEUM
MELANIN
BROWN PIGMENT PRODUCED BY MELANOCYTES IN GERMIN LAYER
DENDRITIC CELLS
LANGERHANS CELLS
FROM BONE MARROW MOVE TO EPIDERMIS AND CONSUME FOREIGN SUBSTANCES
TACTILE CELLS
MERKEL CELLS
LOCATED AT EPIDERMAL-DERMAL JUNCTION
RECEPTORS FOR SENSE OF TOUCH
WHAT CAUSES JAUNDICE
BUILDUP OF BILIRUBIN
TWO COMPONENTS OF DERMIS
SUPERFICIAL PAPILLARY LAYER
DEEPER RETICULAR LAYER
PAPILLARY LAYER
CONSISTS OF AREOLAR TISSUE
CONTAINS CAPILLARIES, LYMPHATICS, SENSORY NEURONS
SEBACEOUS GLANDS
NEAR HAIR FOLLICLES
HOLOCRINE GLANDS THAT SECRETE SEBUM
CHEMICAL BARRIERS OF THE SKIN
MELANIN AND SECRETIONS
LOW PH OF SKIN SECRETIONS IS THE ____
ACID MANTLE
SLOWS MULTIPLICATION OF MICROORGANISMS
DEFENSINS
SUBSTANCES SECRETED BY SKIN CELLS TO HELP KILL BACTERIA
WHAT FORMS THE PHYSICAL BARRIER OF THE SKIN
CONTINUITY AND KERATINIZED CELLS
WHAT TWO TYPES OF SWEAT GLANDS ARE IN THE SKIN
MEROCRINE AND APOCRINE
BIOLOGICAL BARRIERS OF THE SKIN
DENDRITIC CELLS IN EPIDERMIS
MACROPHAGES IN THE DERMIS
BODY’S DNA
SENSORY RECEPTORS
LOCATED IN THE DERMIS AND ARE PART OF THE NERVOUS SYSTEM
“EXTEROCEPTORS” THAT RESPOND TO STIMULI OUTSIDE OF BODY
HOW INTEGUMENTARY SYSTEM HEALS WOUNDS
BLOOD VESSELS OF WOUNDED AREA DILATE AND ALLOW FLUIDS TO LEAK INTO DAMAGED TISSUES
THIS PROVIDE SMORE NUTRIENTS/OXYGEN TO AID IN HEALING
EPITHELIAL CELLS DIVIDE MORE RAPIDLY TO FILL IN
BLOOD DRIES TO BECOME SCAB
FIBROBLASTS FORM NEW FIBERS TO BIND WOUND TOGETHER
CUTANEOUS CARCINOMA
SKIN CANCER ORIGINATING FROM EPITHELIAL CELLS
CUTANEOUS MELANOMAS
CANCER FROM MELANOCYTES
BURN
TISSUE DAMAGED CAUSED BY HEAT THAT KILLS CELLS/DENATURES PROTEINS
WHAT KILLS YOU AFTER BEING BURNED
FLUID LOSS AND DEHYDRATION LEADING TO ELECTROLYTE IMBALANCE, RENAL FAILURE, AND CIRCULATORY SHOCK
FIRST DEGREE BURN
ONLY EPIDERMIS
REDNESS, PAIN, SLIGHT EDEMA
SECOND DEGREE BURN
PARTIAL THICKNESS
EPIDERMIS AND PART OF DERMIS
RED WITH BLISTERS, VERY PAINFUL
THIRD DEGREE BURN
FULL THICKNESS
EPIDERMIS AND DERMIS COMPLETELY DESTROYED
REQUIRE SKIN GRAFTS
WHAT CLASSIFIES A BURN AS CRITICAL
OVER 25% OF BODY WITH 2ND DEGREE
OVER 10% OF BODY WITH 3RD DEGREE
3RD DEGREE BURNS ON FACE, HANDS, OR FEET
