Mblex Study Guide

A condition of homeostasis resulting in a state of physical, emotional, social and spiritual well-being. Health
A signal that travels towards a particular point of reference. Afferent signal
A signal that travels away from a particular point of reference Efferent signal
A control system needed for self regulation that sends, analyzes and actualizes impulses through the body. Feedback Loop
The feedback that reverses the original stimulus, stabilized physiological function & helps us maintain our constant internal environment. Negative Feedback
Feedback that enhances the original stimulus and then maintains or accelerates a disturbed state of homeostasis. Positive Feedback
The internal, periodic timing components of an organism generated within the body. Biologic Rhythms
Biologic Rhythms that work on a 24 hour period. Circadian Rhythms.
Biologic Rhythms that repeat themselves every ninety minutes Ultradian Rhythms
A coordination or synchronization with an internal or external rhythm. Entrainment
Diseases that have a specific beginning, quick onset, last a short time and then disappear Acute Diseases
Diseases that have a vague onset, develop slowly, and last for a long time, sometimes for life. Chronic Diseases
Lesions caused by biochemical compounds such as an antigen, antibody, abnormal enzyme or hormone Biochemical Lesion
Diseases that can be transmitted from one person to another Communicable Diseases
Diseases that are present at birth. Congenital Diseases
Occurs when a medical professional categorizes a disease by identifying it's signs and symptoms. Diagnosis
An abnormality in the function of the body, especially when the abnormality threatens well being. Disease
The field of science that studies the frequency, transmission, occurrence, and distribution of disease in human beings. Epidemiology
The study of all the factors involved in causing disease Etiology
A term that refers to a disease with undetermined causes Idiopathic
Describes the development of disease. Pathogenesis
The study of disease Pathology
Deals with the preparation and the actions of medications and their uses in treating or preventing a disease. Pharmacology
The expected outcome in a client who has a disease. Prognosis
The reversal of signs and symptoms. Can be temporary or permanent Remission
Objective changes that can be seen or measured by someone other than the client Signs
Altered organic structures such as macules, vesicles, blebs, bullae, pustules, papules, tumors, ect. Structural Lesions
Diseases that have characteristics that fall between acute and chronic Subacute Diseases
The subjective changes noticed or felt only by the client. Symptoms
Groups of signs and symptoms that identify a pathologic condition. Syndromes
Malignant, nonencapsulated cells that invade surrounding tissue. Often breaks away and metastasizes from the primary tumor. Cancer
The ability of infectious agents to cause disease Pathogenicity
Organisms that can easily cause disease Virulent
Organisms that cause disease only when immunity is low Opportunistic Pathogens
Pathogenic organism, tiny cells w/o nuclei that secrete toxins, eat body cells, or form colonies Bacteria
Pathogenic Organism, simple plantlike organism that lacks chlorophyll, generally molds or yeast Fungi
Pathogenic Organism, large multicellular organism such as roundworms, mites & lice Pathogenic Animals
Pathogenic Organism, Large one-celled organism having organized nuclei such as amebs. Protozoa
Pathogenic Organism, microscopic intracellular parasites that invade a host cell and take over the cell function to provide more of itself. Virus
Abnormal tissue growth resulting from uncontrolled cell division and results in a neoplasm (tumor) Hyperplasia
Another name for a tumor Neoplasm
A contained, encapsulated tumor that is relatively harmless. Benign Tumor
Abnormal or undifferentiated cells that fail to mature into specialized cell types. Characteristic of malignant cells. Anaplasia
A protective response of the tissues to irritation or injury that may be chronic or acute. Inflammation
A type of tissue repair where new cells are similar to those that they replace. Regeneration
A type of tissue repair where new cells are formed by connective tissue. Scar
a tract leading from a cavity to the surface. Sinus
A tract that is open at both ends, through which abnormal connections occur between two surfaces. Fistual
A private complex abstract experience that is difficult to explain or describe. Pain
A type of pain that exists when the skin is cut or jabbed with a sharp object. This is short lived and easily localized (superficial somatic paint) Pricking-Bright Pain
Type of pain that is slower to develop, lasts longer, localized less accurately. Burning Pain
Type of pain that occurs when the visceral organs are stimulated. Constant pain, not well localized, and commonly referred to areas of the body distant from where the damage may be occurring. Aching Pain
Pain that is poorly localized, nauseating, and is commonly associated with sweating and changes in blood pressure. Initiates the reflex contraction of nearby skeletal muscles. Deep pain
Pain in a muscle that occurs when blood supply is closed off. Muscle pain
Pain that arises from the stimulation of receptors in the skin or from stimulation of receptors in skeletal muscles, joints, tendons, and fasciae. Somatic Pain
Pain that results from the stimulation of receptors in the viscera. Visceral Pain
Pain that may be felt in a surface area far from the stimulated organ Referred Pain
Pain commonly experienced by a person that has undergone amputation Phantom pain
an external or internal stimulus that requires change or response so as to prevent an imbalance in the internal environment of the body, mind or emotions. Stress
The latent stage of disease Incubation
