Health physical, mental, and social well being
disease an abnormality in body function that threatens health
Etiology study of the factors that cause a disease
Idiopathic refers to a disease with an unknown cause
Signs and symtoms the objective and subjective abnormalities associated with a disease
Pathogenesis the pattern of a disease's development
Epidemiology the study of occurrence, distribution, and transmission of diseases in human populations
Endemic diseases native to a local region
Pandemics are widespread, perhaps global epidemics More common due modern air travel
epidemics occur when a disease affects many people at the same time
Disease is difficult to discover, many factors of disease transmission, Can be fought through prevention and therapy( treatment)
Communicable disease that can be transmitted from one person to another
Latent / incubation period time when no sign or symptoms of a disease are evident
Factors involved in spreading disease nutrition, age, gender, sanitation practices, socioeconomic condition
Mechanism of disease genetic mechanism, pathogenic organisms, tumors and cancer, physical and chemical agents, malnutrition, autoimmunity, inflammation, degeneration,
Risk factor certain predisposing conditions that make the development of a disease more likely
type of risk factors genetic factores age, lifestyle stress, environmental factors, preexisting conditions
Virus description intercellular parasite that consists of a nucleic acid (RNA, DNA) surrounded by a protein coat and sometimes by a lipoprotein envelope
Virus invades the cell and inserts its own genetic code into th host cell's genetic code, causing cell to produce viral DNA or RNA and protein coats.Pirates host cell's nutrients and organelles to produce more virus particles
Prions pathogenic protein molecules
Bacterium tiny, primitive cell without nucleus. Secrete toxic substance that damage tissue, become parasites inside human cell, can form colonies in the body disrupt normal function
Aerobic bacteria requires oxygen for their metabolism
Anaerobic bacteria requires an absence of oxygen for their metabolism
Bacilli bacteria large, rod-shaped cells found singly or in groups
Cocci bacteria large round, found singly, in pairs, in strings, or in clusters
Curved or spiral rods bacteria curved rods arranged singly or in strands; large spiral cells or cell colonies
Small bacteria round or oval, are so small they were thought to be virus. only reproduce inside other living cells. (Obligate parasites)
Fungi group of simple organisms similar to plants but without chlorophyll
Pathogenic animals ( Metazoa ) large multicellular organisms
Paillomas, Adenomas, Nevi benign tumors that arise from epithelial tissue
Lipomas, Osteomas, Chondromas benign tumors that arise from connective tissue
Sarcomas type lymphomas, osteosarcomas, myelomas fribrosarcomas
factor of development cancer genetics, carcinogens, age, environment, viruses
methods of detecting cancer self examination, diagnostic imaging, biopsy blood test
cancer treatment surgery chemotherapy radiation therapy, immunotherapy, gentic engineering
primary signs for inflammation redness, heat, swelling, pain
Chemotaxis movement of white blood cells in response to chemical attractants
positive affect of fever increased temperature often kills or inhibits the growth of pathogenic microbes, may enhance activity of immune system
vaccine killed or attenuated pathogen, stimulate immunity
antibiotics chemicals produced by certain living organisms, inhibits growth of or kill pathogens
spores formed by bacteria, able to survive heat, various chemicals, dry conditions
Protozoa one cell organisms larger than bacteria, DNA organized in a nucleus
Amoebas pathogenic protozoa, large cells of changing shape
Flagellates pathogenic protozoa, move by wiggling long, whiplike extensions
Ciliates pathogenic protozoa, move by means of many short, hairlike projections
Sporozoa pathogenic protozoa, unusual organelles tips allow them to enter host cell (Coccidia)
Pathogenic animals Metozoa, large multicellular organisms,
Nematodes pathogenic animals, large parasites m round worm, transmitted by food or flies that bite
Platyhelminths pathogenic animals, large parasites, flatworms, flukes, infest several human organs
Arthropods pathogenic animals, grpup of parasites, include Mites, Ticks, Lice, Fleas
Aseptic methods that prevent spread of pathogens Sterilization, disinfection, Antisepsis, Isolation
Microbes Microscopic organisms that include bacteria, fungi, and protozoa are called
A vector of the disease is organism that spreads disease to other organism
Adenoma benign tumor forms from glandular epithelium.
Melanoma cancer that involves melanocytes
Adenocarcinoma general term for malignant tumors of glandular epithelium
Sarcomas malignant tumor arises from connective tissues
Lymphoma cancer of lymphatic tissue
Osteosarcoma malignant tumor of bone tissue
Myeloma malignant bone marrow tumor
Fibrosarcoma general term cancer involving fibrous tissue
Hyperplasia produces to many cells
anaplasia process of production of abnormal or undifferentiated tumor cells
Oncogenes cancer genes
neuroblastoma malignant tumor arises from nerve tissue
Carcinogens cancer markers, chemicals affect genetic activity, abnormal cell reproduction
Mutagens mutation markers, cause changes in a cell's DNA structure
Pathogenesis mechanism of disease's development, (Pattern)
Pathophysiology the organized study of the underlying physiological processes associated with disease
yeast small single cell fungi
Genetic mechanism altered or mutated genes than can cause ;production of abnormal proteins
Infectious mechanism pathogenic organisms or particles that damage the body in some way
Neoplastic mechanism abnormal tissue growths or neoplasms (tumors [benign or malignant] and cancers) that can cause a variety of physiological disturbance
traumatic mechanism physical and chemical agents, extreme heat and cold, mechanical injury (trauma) and radiation
Metabolic mechanism endocrine imbalance or malnutrition causes insufficient or imbalanced intake of nutrition
Inflammatory mechanisms: Autoimmunity faulty response or over reaction of the immune system that causes it to attack th body
Inflammatory mechanisms: Inflammation common response of the body to disturbances
Degeneration breaking apart degeneration of tissues by means of many still unknown processes
Gram positive bacteria that stain purple
virus pathogen that can cause warts and infectious mononucleosis
Leukemia cancer of blood tissue
Cachexia syndrome appetite loss, weight loss, general weakness
Metastasis cell leave a primary tumor and start a secondary tumor at a new location
Papilloma benign epithelial tumor finger like projection
Pus inflammatory exudate
inflammation mediators Histamine, Prostaglandins, Kinins
Inflammatory response redness, heat, swelling (edema), pain
