Answer 1

EPIDERMIS (OUTER LAYER)
DERMIS (INNER LAYER)

Question 2

SUBCUTANEOUS LAYER

Answer 2

BELOW THE DERMIS
BINDS SKIN TO DERMIS

Question 3

KERATINOCYTES

Answer 3

CELLS THAT MOVE TOWARD SKIN SURFACE, RECEIVE FEWER NUTRIENTS, AND DIE
HARDEN WITH AGE

Question 4

LAYERS OF EPIDERMIS

Answer 4

INNER TO OUTER:
BASALE
SPINOSUM
GRANULOSUM
LUCIDUM
CORNEUM

Question 5

MELANIN

Answer 5

BROWN PIGMENT PRODUCED BY MELANOCYTES IN GERMIN LAYER

Question 6

DENDRITIC CELLS

Answer 6

LANGERHANS CELLS
FROM BONE MARROW MOVE TO EPIDERMIS AND CONSUME FOREIGN SUBSTANCES

Question 7

TACTILE CELLS

Answer 7

MERKEL CELLS
LOCATED AT EPIDERMAL-DERMAL JUNCTION
RECEPTORS FOR SENSE OF TOUCH

Question 8

WHAT CAUSES JAUNDICE

Answer 8

BUILDUP OF BILIRUBIN

Question 9

TWO COMPONENTS OF DERMIS

Answer 9

SUPERFICIAL PAPILLARY LAYER
DEEPER RETICULAR LAYER

Question 10

PAPILLARY LAYER

Answer 10

CONSISTS OF AREOLAR TISSUE
CONTAINS CAPILLARIES, LYMPHATICS, SENSORY NEURONS

Question 11

SEBACEOUS GLANDS

Answer 11

NEAR HAIR FOLLICLES
HOLOCRINE GLANDS THAT SECRETE SEBUM

Question 12

CHEMICAL BARRIERS OF THE SKIN

Answer 12

MELANIN AND SECRETIONS

Question 13

LOW PH OF SKIN SECRETIONS IS THE ____

Answer 13

ACID MANTLE
SLOWS MULTIPLICATION OF MICROORGANISMS

Question 14

DEFENSINS

Answer 14

SUBSTANCES SECRETED BY SKIN CELLS TO HELP KILL BACTERIA

Question 15

WHAT FORMS THE PHYSICAL BARRIER OF THE SKIN

Answer 15

CONTINUITY AND KERATINIZED CELLS

Question 16

WHAT TWO TYPES OF SWEAT GLANDS ARE IN THE SKIN

Answer 16

MEROCRINE AND APOCRINE

Question 17

BIOLOGICAL BARRIERS OF THE SKIN

Answer 17

DENDRITIC CELLS IN EPIDERMIS
MACROPHAGES IN THE DERMIS
BODY’S DNA

Question 18

SENSORY RECEPTORS

Answer 18

LOCATED IN THE DERMIS AND ARE PART OF THE NERVOUS SYSTEM
“EXTEROCEPTORS” THAT RESPOND TO STIMULI OUTSIDE OF BODY

Question 19

HOW INTEGUMENTARY SYSTEM HEALS WOUNDS

Answer 19

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

Question 20

CUTANEOUS CARCINOMA

Answer 20

SKIN CANCER ORIGINATING FROM EPITHELIAL CELLS

Question 21

CUTANEOUS MELANOMAS

Answer 21

CANCER FROM MELANOCYTES

BURN

Answer 22

TISSUE DAMAGED CAUSED BY HEAT THAT KILLS CELLS/DENATURES PROTEINS

Question 23

WHAT KILLS YOU AFTER BEING BURNED

Answer 23

FLUID LOSS AND DEHYDRATION LEADING TO ELECTROLYTE IMBALANCE, RENAL FAILURE, AND CIRCULATORY SHOCK

Question 24

FIRST DEGREE BURN

Answer 24

ONLY EPIDERMIS
REDNESS, PAIN, SLIGHT EDEMA

Question 25

SECOND DEGREE BURN

Answer 25

PARTIAL THICKNESS
EPIDERMIS AND PART OF DERMIS
RED WITH BLISTERS, VERY PAINFUL

Question 26

THIRD DEGREE BURN

Answer 26

FULL THICKNESS
EPIDERMIS AND DERMIS COMPLETELY DESTROYED
REQUIRE SKIN GRAFTS

Question 27

WHAT CLASSIFIES A BURN AS CRITICAL

Answer 27
