Exam #1 Review Flashcards
This terms means the physiology of altered health - changes in cells, tissues, and organs of the body that cause of are caused by disease
Pathophysiology
This term means an acute or chronic illness that one acquires or is born with that cause physiologic dysfunction in one or more body system
Disease
The cause of disease; what sets the disease process into motion
Etiology
What are the three different agents of etiology?
- Biologic
- Physical
- Chemical
What are the two different types of etiology?
- Congenital
- Acquired
How the disease process evolves, the sequence of cellular and tissue events that take place from initiation
Pathogenesis
These are objective and something an observer can see
Signs
These are subjective and what the person with the disease feels and tells you about
Symptoms
A compilation of signs and symptoms that are characteristic of a disease state
Syndrome
The designation as to the nature or cause of a health problem
Diagnosis
The study of factors, events, and circumstances that influence the transmission of infectious diseases among human populations
Epidemiology
The number of new cases arising in a population at risk during a specified time; the information on the risk of contracting the disease, probability of being diagnosed - the number of new cases of an infectious disease that occur within a defined population and time
Incidence
A measure of existing disease in a population at a given point in time; how widespread the disease is - the number of active cases at any given time
Prevalence
The causes of death in a population
Mortality
The effects an illness has on a person’s life (long-term consequences)
Morbidity
This type of disease prevention means keeping the disease from occuring by removing risk factors
Primary prevention
This type of disease prevention means detecting disease early when it is still asymptomatic and treatment can affect a cure or stop progression
Secondary prevention
This type of disease prevention includes clinical interventions that prevent further deterioration or reduce complications once a disease is diagnosed
Tertiary prevention
The smallest functional unit that has the characteristics necessary for life - most disease processes begin at this level
Cells
What are the three major components of the eukaryotic cell
Nucleus, cytoplasm, and cell membrane
This part of the cell contains DNA, instruction on how to make proteins, and is the site for RNA synthesis
Nucleus
This part of the cell controls cell shape and movement and is made of microtubules to develop and maintain cell from
Cytoskeleton
Scheduled/programmed cell death
Apoptosis
Cell death due to injury or infection
Necrosis
When large amounts of tissue undergo necrosis
Gangrene
When cells surround and take in materials from their surrounding
Endocytosis
Known as cell drinking
Pinocytosis
Known as cell eating
Phagocytosis
Secretion of intracellular substances into extracellular spaces
Exocytosis
This term means:
- New growth
- Growth is uncoordinated and relatively autonomous
- Lacks normal regulatory controls over cell growth and division
- Tends to increase in size and grow after stimulus ceases or needs of the organism are met
Neoplasia
Mass of cells due to overgrowth
Tumors
Benign tumor of glandular epithelial tissue
Adenoma
Malignant tumor of glandular epithelial tissue
Adenocarcinoma
Malignant tumor of epithelial tissue
Carcinoma
Benign tumor of bone tissue
Osteoma
Benign microscopic or macroscopic finger-like projections growing on a surface
Papillomas
Less common tumor that grows in connective tissue such as bones, muscles, tendons, cartilage, nerves, fat, and blood vessels
Sarcoma
Evidence of a genetic trait - may or may not be visible to the naked eye
Gene expression
22 pairs of chromosomes alike in both males and females
Autosomal chromosomes
This disorder occurs in one of the 22 pairs of chromosomes
Autosomal disorders
Persons in whom the two alleles of a given pair are the same (AA or aa)
Homozygous
Persons having different alleles (Aa) at a gene locus
Heterozygous
These disorders are due to a combination of chromosomal and environmental factors
Multifactorial disorders
A connective tissue disorder manifested by changes in the skeleton, eyes, and cardiovascular system - autosomal dominant
Marfan syndrome
A condition involving neurogenic tumors that arise from Schwann cells and other elements of the peripheral nervous system - autosomal dominant
Neurofibromatosis (NF)
A rare metabolic disorder caused by a deficiency of the liver enzyme phenylalanine hydroxylase - autosomal recessive
Phenylketonuria (PKU)
A variant of a class of lysosomal storage diseases, known as gangliosidosis - the membranes of nervous tissue that are deposited in neurons of the central nervous system and retina because of a failure of lysosomal degradation - autosomal recessive
Tay-Sachs Disease
Trisomy 21 is known as
Down syndrome
This chromosomal disorder occurs in females and is due to an alteration in chromosome number
Monosomy X (Turner syndrome)
This chromosomal disorder occurs in males and is due to an alteration in chromosome number
Polysomy X (Klinefelter syndrome)
This stage of general adaptation syndrome involves catecholamines and cortisol release
Alarm
This stage of general adaptation syndrome involves adapting and calming and techniques such as meditation and relaxation are used to extend it
Resistance
This stage of general adaptation syndrome occurs when one can no longer maintain normal
Exhaustion
When local inflammation or trauma occurs
Local adaptation syndrome
These are the smallest pathogens, have no organized cellular structure, are incapable of replication outside a living cell
Viruses
These reproduce by division and are larger than viruses
Bacteria
How are bacteria classified
By appearance and by gram-staining
Single-celled organisms that behave more like animals (small parasites)
Protozoa
These are larger than bacteria and have separate nucleus
Fungi
These are organisms that live off of other organisms (host) without benefit to the host
Parasites
Which cells work as phagocytotic cells during inflammation
Neutrophils
Which cells work during allergic reactions and parasitic infections
Eosinophils
Which cells produce Histamine during inflammation
Basophils and Mast cells
This is caused by:
- brief vasoconstriction
- rapid vasodilation (causes heat/redness)
- forces fluid into extracellular spaces (pain, swelling, loss of function)
- Cause ‘clampdown’ of vasculature to decrease bleeding
Acute inflammation
The collective, coordinated response of the cells and molecules of the immune system
Immune defense
The natural resistance with which a person is born
Innate or nonspecific immunity
