CHAPTER NINE
| Question | Answer |
|---|---|
| HOW MANY SENSE ORGANS ARE THERE OF THE BODY?//THE FOLLOWING SENSES COMES TO MIND | 1. MANY//2. SIGHT, HEARING, SMELL, TAST, AND TOUCH |
| SENSORY RECEPTORS ARE?//DENDRITES ARE? | 1. MICROSCOPIC-SIZED SENSE ORGANS//2. SENSORY NEURONS(NERVE CELLS) |
| SENSE OF TOUCH UTILIZES THE LARGEST ORGAN OF THE BODY | THE SKIN |
| THE SKIN HAS THREE MAIN LAYERS: | 1. EPIDERMIS//2. DERMIS//3. SUBCUTANEOUS |
| THE DERMIS CONTAINS | MOSTLY FIROBLAST THAT ARE RESPONSIBLE FOR SECRETING COLLAGEN, ELASTIN, AND GROUND SUBSTANCE |
| THE DERMAL HOUSES | HAIR FOLLICLESBLOOD VESSELSSEEAT AND OIL GLANDS |
| THE DERMIS IS ATTACHED TO | AN UNDERLYING SUBCUTANEOUS LAYER CALLED HYPODERMIS--OUTERMOST PART OF THE MUSCLE |
| THE SUBCUTANEOUS LAYER STORESTHE SUBCUTANEOUS LAYER CONTAINES | ADIPOSETHE CONNECTIVE TISSUE |
| THE DERMIS HELPS TO KEEP THE BODY TEMP NORMAL | 98.6 DEGREES F |
| THE SKIN OR EPIDERMIS PROVIDES PROTECTION FROM | ULTRA VIOLET RADIATIONINFECTION |
| EXPOSURE OF SUNLIGHT TO THE SKIN PRODUCES | VITAMIN D |
| THE LARGEST SENSORY ORGAN PROVIDES THE BODY THE ABILITY TO | FEEL HEAT, COLDPAIN & PLEASURE |
| NEEDED TO HELP MAKE CHOLESTEROL AND TO ABSORB CALCIUM AND PHOSPHORUS TO MAKE STRONG BONES | VITAMIN D |
| RASH: | AN AREA OF RED, INFLAMED SKIN OR A GROUP OF RED SPOTS CAUSED BY IRRITATION, ALLERGY, INFECTION OR DEFECTS TOT HE SKIN'S STRUCTURE, SUCH AS BLOCKED PORES OR MALFUNCTIONING OIL GLANDS. ACNE, CONTACT DERMATITIS, ECZEMA, HIVES, ROSEA AND PSORIASIS |
| ECZEMA | INFLAMMATION WITH PIMPL-LIKE BUMPS CHARACTERIZED BY ITCHING, RED, BLISTERING, OR OOZING AREAS OF THE SKIN, PROGRESSING TO SCALY, BROWNISH, OR THICKENED SKIN |
| PSORIASIS | CHRONIC IMMUNE DISORDER IN WHICH SPECIFIC IMMUNE CELLS BECOME OVERACTIVE AND RELEASE EXCESSIVE AMOUNTS OF PROTEINS CALLED CYTOKINES |
| APRIL 30, 2004 | FDA APPROVED A NEW SUBCUTANEOUS INJECTABLE DRUG FOR PSORIASIS |
| VIRAL INFECTIONS | VIRUS WHICH PENETRATES THE STRATUM CORNEUM AND INFECTS THE INNER LAYERS OF THE SKIN |
| ANTIBIOTICS OR ANTIBACTERIAL AGENTS | CANNOT CURE VIRAL INFECTIONS |
| WARTS | CAUSED BY THE HUMAN PAPILLOMA VIRUS(HPV), NOT CURABLE, BUT THE DRUN CAN DECREASE THE SIZE AND SEVERITY OF PAIN |
| HPV | THE MOST COMMON SEXUALLY TRANSMITTED DISEASE |
| BACTERIAL SKIN INFECTIONS | CAUSED BY MANY DIFFERENT BACTERIA, MOST COMMON TYPES ARE: STAPHYLOCOCCI, STREPTOCOCCI & PSEUDOMONAS |
| STSTEMIC INFECTIONS ARE | LYME DISEASEIMPEL FOLLICULITISCELLULITIS |
| MOST COMMON BACTERIAL SKIN INFECTIONS ARE: | 1. CELLULITIS//2. IMPETIGO//3. FOLLICULITIS |
| ACNE | BACTERIAL INFECTION CAUSED BY PROPIONI BACTRERIUM & AN OVERPRODUCTION OF SEBUM |
| SEBUM | CAUSES AND INCREASE IN HAIR FOLLICLES DURING PUBERTY. |
| INCREASED WHITE BLOOD CELLS ATTACK THE HAIR FOLLICLES CAUSING | INFLAMMATION THAT LEADS TO PAPULES, PUSTULES,& NODULES |
| CELLULITIS | AN ACUTE DEEP INFECTION OF THE CONNECTIVE TISSUE OF THE SKIN ACCOMPAINED BY INFLAMMATION |
| ENZYMES | DESTROYS THE SKIN CELLS |
| FUNGAL SKIN INFECTIONS | KNOWN AS MYCOSES, OCCCUR WHEN HARMLESS FUNGI WHICH ARE USUALLY PRESENT(PARASITES OR SPROPHYTES), GAIN ENTRY INTO THE SKIN RATHER THAN STAYING ON THE OUTER LAYER OF THE SKIN.EXTERNAL--AFFECTING THE SKIN, HAIR AND NAILS |
| YEAST | FORMS A SUBTYPE OF FUNGUS, CHARACTERIZED BY CLUSTERS OF ROUND OR OVAL CELLS |
| FUNGAL INFECTIONS OCCUR//YEAST INFECTIONS | 1. IN DAMP, DARK AND WARM ATMOSPHERES//2. MUST HAVE SUGAR |
| EXAMPLES OF FUNGAL INFECTIONS | ATHLETE'S FOOTJOCK ITCHRINGWORM |
| ATHLETE'S FOOT | TYPICALLY HAVE ITCY READ AREAS THAT MAY CRACK OR BLISTER |
| PARASITIC INFECTIONS | CAUSED BY INSECTS OR WORMS THAT BURROW INTO THE SKIN TO LIVE AND/OR LAY THEIR EGGS |
| SCABIES | CHARACTERIZED BY SMALL RED BUMPS AND INTENSE ITCHING CAUSED BY MITES THAT BURROW IN THE SKIN FROM BEDDING AND MATTRESSES |
| THREE TYPES OF HUMAN LICE | HEADBODYPUBIC |
| TUMORS AND CANCEROUS GROWTHS | OCCUR WHEN SKIN CELLS MULTIPLY(EPRODUCE)FASTER THAN NORMAL |
| HOW MANY AFFECTED BY SKIN CANCER EACH YEAR | 800,000 & 90% CAUSED BY CONT.OR EARLY-LIFE SUN EXPOSURE |
| BASAL CELL CARCINOMA | MOST CURABLE, MOST COMMON SKIN CANCER. COMMONLY PRESENTS ON THE FACE AND SCALP AND IS MAINLY CAUSED BY SUN EXPOSURE, OFTEN COMMENCING IN CHILDHOOD |
| SQUAMOUS CELL CANCER | SECOND MOST COMMON SKIN CANCER. IT GROWS AND SPREAD RAPIDLY, OFTEN APPEARING ON THE BACK OF THE HANDS, ON THE EARS, OR ON THE EDGES OF THE LIPS. |
| MALIGNANT MELANOMA | THE MOST DEADLY FORM OF SKIN CANCER, THE SIGNAL IS A MOLE THAT CAHNGES SHAPE OR COLOR AND BEGIN TO BLEED |
| ACTINIC KERATOSIS(AK) | CALLED A SOLAR KERATOSIS, IS A CALY OR CRUSTY BUMP THAT ORGINATES ON THE SKIN SURFACE |
| PIGMENTATION DISORDERS | SKIN COLOR IS DETERMINED BY THE AMOUNT OF MELANIN PRODUCED BY THE BODY AND TO COME EXTENT GENETICS |
| MISCELLANEOUS SKIN CONDITIONS AND DISEASES THAT DO NOT FALL UNDER ANY OF THE PRECEDING CATEGORIES ARE | HYPERKERATOSISWRINKLING ROSACEASPIDER VEINSVARICOSE VEINS |
| HYPERKERATOSIS | A CONDITION OF HAVING TOO MUCH KERATIN |
| KERATIN | PROTEIN OF THE SKIN, HAIR & NAILS |
| WRINKLES | CAUSED BY THE COMBINATION OF A BREAKDOWN OF THE COLLAGEN AND ELASTIN WITH THE DERMIS AND FAT CELLS IN THE SKIN BECOMING SMALLER WHICH RESULTS IN SAGGING SKIN |
| ROSACEA | A CHRONIC DISORDER OF UNKNOWN CAUSE IN WHICH THE SKIN OF THE FACE BECOMES RED(ERYTHEMA)AND DEVELOPS PIMPLS, LESIONS AND POSSIBLY AND ENLARGEMENT OF THE NOSE |
| SPIDER VEINS | BROKEN BLOOD VESSELS, SUCH AS CAPILLARIES, WHICH THEN ENLARGE |
| BURNS | SUSCEPTIBLE TO INFECTION DUE TO THE OPEN LESIONS |
| FDA DEFINES COSMETICS AS | ARTICLES INTENDED TO BE RUBBED, POURED, SPRINKLED OR SPRAYED ON INTRODUCED INTO OR OTHERWISE APPLIED TO THE HUMAN BOY OR ANY PART THEREOF FOR CLEANSING, BEAUTIFYING, PROMOTING ATTRACTIVENESS OR ALTERING THE APPEARANCE(EXCLUDES SOAP) |
| FDA DEFINES DRUG AS | ARTICLES INTENDED FOR USE IN THE DIAGNOSIS, CURE, MITIGATION, TREATMENT OR PREVENTION OF DISEASE IN MAN OR OTHER ANIMALS AND ARTICLES(OTHER THAN FOOD)INTENDED TO AFFECT THE STRUCTURE OR ANY FUNCTION OF THE BODY OF MAN OR OTHER ANIMALS |
| MOST SKIN CONDITIONS CAN BE PREVENTED WITH | A SIMPLE DAILY ROUTINE--KEEP SKIN CLEAN AND FREE FROM DIRT WITH DAILY GENTLE WASHING |
| THE SKIN EXCRETES | SALTS AND EXCESS WATER FROM THE BODY |
| THE SKIN ACTS AS A SHOCK ABSORBER TO | PROTECT UNDERLYING ORGANS |
| ACNE AFFECTS APPROXIMATELY | 17 MILLION AMERICANS |
