![]() ![]() antigen - any substance, almost always a protein, not normally present in the body which when introduced to the body stimulates a specific immune response and the production of antibodies.Synthesized by B lymphocytes that have been activated by the binding of a antigen to a cell surface receptor. antibody - an immunoglobulin molecule that reacts with a specific antigen that induced its synthesis.anomaly - an irregularity or deviation from normal an abnormal structure.angiogenesis - the formation of new blood vessels.pectoris, paroxysmal pain in the chest often radiating to the arms usually due to interference with the supply of oxygen to the heart muscle often precipitated by excitement or effort. angina - spasmodic, choking or suffocating pain. a.aneurysm - a ballooning out of the wall of a blood vessel or a heart chamber due to a weakening of the wall by disease or injury.anencephaly - markedly defective development of the brain, cerebral hemispheres absent or reduced to small masses, together with absence of the bones of the cranium.anastomosis - a connection between two blood vessels or tubes.anaplasia - loss of differentiation of cells and of their orientation to one another and to their framework and blood vessels.anaphylaxis - the immediate immunologic (allergic) reaction initiated by the combination ofantigen (allergen) with mast cell cytophilic antobody (chiefly IgE). anaphylactic (adj) - as in anaphylactic shock - life threatening respiratory distress, vascular collapse and shock manifesting extremely great sensitivity to foreign protein or other material.analgesia ( analgesic) - the absence of pain removing pain.The associated disease states may be inflammatory, hereditary or neoplastic and the deposition may be local or generalized or systemic. amyloidosis - a group of conditions of diverse etiologies characterized by the accumulation of insoluble fibrillar proteins (amyloid) in various organs and tissues of the body - eventually organ function is compromised.amyloid light chain (AL) - a component of immunoglobulin, occurs in mulitple myeloma amyloid associated protein (AA) - derived from liver protein, occurs in reactive systemic amyloidosis amyloid familial (AF) - abnormal transthyretin. There are several precursor proteins which are then deposited in the tissue as amyloid e.g.Each fibril is composed of identical polypeptide chains arranged in stacked antiparallel beta-pleated sheets (this is what impar ts the characteristic birefringence under polarized light). Amyloid deposits are composed of straight, non-branching fibrils with a diameter of 7.5 to 10 nm and indefinite length.It is a waxy, amorphous, eosinophilic, hyalinelike material that exhibits red-green birefringence under polarized light when stained with Congo red. amyloid - the extracellular protein substance deposited in amyloidosis.amine - a chemical substance in the body whose structure is similar to ammonia a family of hormones (adrenal medulla - epinephrine & norepinephrine) or neurotransmitters in brain (dopamine, norepinephrine, epinephrine, serotonin).amino acid(s) - the basic building block of protein there are 20 common amino acid types and their sequence will determine the properties and function of each protein.amenorrhea - the absence of menstrual bleeding.akinesia ( akinetic = adj.) - absence or loss of movement.aggregation - a total or coming together of separate parts.agglutination - clumping together of cells or particles.agenesis - absence or failure of formation of any part or organ.afferent nerves carry impulses toward the central nervous system. of the uterus, including the uterine tubes and ligaments and ovaries. adnexal - appendages or accessory structures of an organ, e.g.adhesion - in close proximity joining of parts to one another which may occur abnormally as in a fibrous band of scar tissue that binds together normally separate anatomical structures.adenosis - a disease of a gland, often marked by the abnormal formation or enlargement of glandular tissue.adenoma - a benign tumor made up of glandular elements.adenocarcinoma - a malignant tumour originating in glandular tissue.acute - a disease with sudden onset of signs and a short course.in the lung the basic unit of gas exchange, each acinus is supplied by a single terminal bronchiole in the liver, the smallest functional unit. acinus (acini = pl.) - a small sac-like dilatation, e.g.openings such as the pylorus, cardia or other sphincter muscles) especially failure of the esophageal sphincter to relax with swallowing. ![]() achalasia - failure to relax especially referring to smooth muscle fibers at any junction of the gastrointestinal tract (e.g.abscess - a localized collection of pus in a cavity formed by disintegration of tissues. ![]()
