A+ GRADED. Homeostasis A tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level Pathophysiology The study of how disease processes affect the function of the body Pathology The study of changes in cells and tissues as a result of injury or disease Physiology The study of body function Anatomy The study of body structure Disease The functional impairment of cells, tissues, organs, or organ systems Sydrome Specific conditions with recognizable predictable patterns Pathogenesis Development of disease Risk factors Actions or behaviors that represent a potential health threat Etiology Cause of disease Pathogen An organism that causes disease Idiopathic Unknown cause Local Disease confined to a specific site Systemic Disease throughout the body Acute Began abruptly within the last few days/months Chronic Gradual onset lasts longer than 6 months, can have symptom free periods. Insidious Proceeding in a gradual, subtle way, but with harmful effects Remission Symptom free periods Exacerbation Flare up of symptoms Subacute Intermediate between acute and chronic Asymptomatic Without symptoms Diagnosis Labeling of a disease a patient has Prognosis A prediction of the probable course and outcome of a disease Morbidity A negative outcome with disease complications that impact the quality of life Prevelance The number or proportion of cases of a particular disease or condition present ina population at a given time. Endemic Predictable and stable incident prevalence Epidemic Increase in incidence and prevelance Pandemic Epidemic worldwide. Primary prevention Protecting one from developing an injury or disease Secondary prevention Early detection and treatment of disease Tertiary prevention Rehabilitation after diagnosis Evidence based practice Practice based on the best available evidence, patient preferences, and clinical judgement Concept General idea applied in similar solutions Plasma membrane The barrier separating the cell from its external environment Phospholipids Po4 bound to a lipid Hydrophilic Water loving (po4) Organelles Structures that allow the cell to function Cytosol Fluid portion of cytoplasm Endoplasmic reticulum Produces proteins and fats and regulates ions Smooth endoplasmic reticulum Makes lipids, lipoprotein, and steriod hormones regulates calcium Rough endoplasmic reticulum Ribosomes attach to produce proteins Golgi apperatus Preps substances produced by the endoplasmic reticulum for transport out of the cell Lysosome Digestive organelle where macromolecules are hydrolyzed Peroxisome Oxidases and neutralizes molecules with unpaired electrons Mitochondrion Cellular respiration 34 atp made with 1 molecule of c6h1206 Deoxiribonucleic acid (dna) 23 pairs of chromosomes Chromosomes 23 pairs in each cell Chromatin Clusters of dna, rna, and proteins in the nucleus ofa cell Membrane pore Passages in and out of the cell Osmosis Water in/out of cell by concentration gradient Osmotic pressure Pressure from osmosis Facilitated diffusion Movement of specific molecules across cell membranes through protein channels Active transport Require atp for transport Electrochemical gradient Movement against gradient- sodium potassium pump Primary active transportation Move large molecules across the membrane Secondary active transport Form of active transport which does not use atp as an energy source; rather, transport is coupled to ion diffusion down a concentration gradient established by primary active transport. Cotransport The coupling of the "downhill" diffusion of one substance to the "uphill" transport of another against its own concentration gradient. Countertransport One substance moves in while another moves out Endocytosis How large particles enter the cell Aerobic respiration Respiration that requires oxygen Glycolisis Creates pyruvate +2 atp Citric acid cycle Completes the breakdown of glucose Feed back mechanism Regulates gene activation Receptor Protein that detects a signal molecule and performs an action in response Ligands Key to produce a response Signal transduction Ligand + receptor Binding affinity The strength of the interaction between a ligand and the protein molecule to which it binds. Paracrine signaling Signal released from a cell has an effect on neighboring cells. Endocrine signaling Secreted molecules diffuse into the bloodstream and trigger responses in target cells anywhere in the body Proliferation Increase in cell number Differentiation Process in which cells become specialized in structure and function Symptoms of adenoid hypertrophy Snoring, bad breath, stuffy nose, sleep apnea, pulmonary hypertension, heart failure Hyperplasia Increase in number of cells caused by hormone signaling and increased workload Metaplasia Changing of one cell type to another Condition link with metaplasia Gerd Dysplasia A change in cell size, shape, or arrangement caued by a stressor and has abnormal cell division Mutation Changes in the genetic material- can become cancer Bronchopulmonary dysplasia (bpd) A chronic lung disorder that may affect infants who have been exposed to high levels of oxygen therapy and ventilator support Symptoms of bronchopulmonary dysplasia Subcostal and intercostal retractions Decreased breath sounds Cyanosis Nasal flaring Pulmonary hypertension Wheeze Apoptosis Programmed cell death Syndactyly Fusion of fingers or toes due to lack of apoptosis as fetus Necrosis
