Flashcards in Week 11 Deck (49):
redness of the skin caused by congestion of the capillaries in the lower layers of the skin. It occurs with any skin injury, infection or inflammation.
a parasite that lives within the body of the host./a parasite living on the surface of the host's body.
abnormally decreased pigmentation./abnormally increased pigmentation.
Acral Lick Dermatitis (ALD)
a skin disorder in dogs caused by their licking of a localized area of skin, usually on the lower limbs and particularly over the carpus or metatarsal region. The initiating cause is believed to be psychological but the area quickly becomes traumatized, often secondarily infected, and apparently pruritic which serves to intensify the licking and worsening of the lesion. Called also neurodermatitis, acral pruritic nodule, acropruritic nodule or granuloma, acral lick granuloma.
situated on or near the surface.
hypertrophy of the horny layer (stratum corneum) of the skin/a decreased thickness of the stratum corneum of the skin.
a liver disease characterized pathologically by the loss of the normal microscopic lobular architecture and regenerative replacement of necrotic parenchymal tissue with fibrous bands of connective tissue which eventually constrict and partition the organ into irregular nodules. The term is sometimes used to refer to chronic interstitial inflammation of any organ.
inflammation of the meninges
something perceived by the senses of the clinician
the cellular covering of internal and external surfaces of the body, including the lining of vessels and other small cavities. (more in book)
sudoriferous glands that develop in association with hair follicles and undergo enlargement and secretory development at puberty; they secrete a viscous, odorless sweat that supports bacteria growth leading to production of an acrid odor; secretion is by a merocrine, not apocrine, mechanism.
the escape of blood from a ruptured vessel. Hemorrhage can be external, internal, or into the skin or other tissues. (more in book)
any purulent skin disease. Includes pustule, pimple, acne, impetigo and furunculosis.
1. the persistent sequential occurrence of furuncles over a period of weeks or months.
2. the simultaneous occurrence of a number of furuncles.
a clinical syndrome involving type I hypersensitivity (allergy) with a hereditary predisposition. Immunoglobulin E (IgE) is involved.
pertaining to the space within a body cavity.
a localized collection of pus in a cavity formed by the disintegration of tissue. Most abscesses are formed by invasion of tissues by bacteria, but some are caused by fungi or protozoa or even helminths, and some are sterile. (more in book)
neopasia: lthe formation of a neoplasm
the diffusion of solute molecules through a semipermeable membrane, passing from the side of higher concentration to that of the lower; a method sometimes used in cases of defective renal function to remove from the blood elements that are normally excreted in the urine (hemodialysis). The principles of dialysis are utilized in renal dialysis with a hemodialyzer (hemodialysis) and in peritoneal dialysis.
removal of the head, as of an animal, fetus or bone.
a skin disease of domestic animals, caused by a number of genera of mites and described under those headings.
the term used to describe the condition caused by a diet that contains all of the essential nutrients but in suboptimal amounts—an intermediate stage to starvation. (more in book)
fungal infection of the skin caused by one of the pathogenic genera, Microsporum, Trichophyton or Epidermophyton
inflammation of a follicle(s); used ordinarily in reference to hair follicles, but sometimes in relation to follicles of other kinds.
superficial traumatic abrasions and scratches which remove some of the skin substance. Commonly caused in animals by rubbing or scratching pruritic skin.
in its normal place; confined to the site of origin.
1. conversion into a spray.
2. treatment by a spray.
platelet: a small disk or platelike structure, the smallest of the formed elements in blood.
inflammation of the brain. Changes in vessel walls, as well as of nervous tissue, are almost a constant feature of encephalitis. (more in book)
emanating from or pertaining to liver.
1. gliding; moving from point to point over the surface; unstable; fluctuating.
2. chemically unstable.
pertaining to or situated at or near the periphery.
a substance secreted to the outside of the body and perceived (as by smell) by other individuals of the same species, releasing specific behavior in the percipient.
Destructive to parasites.
infection by a pathogen following an infection by a pathogen of another kind.
inflammation of the skin. Dermatitis can result from various animal, vegetable and chemical substances, from heat or cold, from mechanical irritation, from certain forms of malnutrition, or from infectious disease.
having a rank, disagreeable smell.
any disease-producing agent or microorganism.
to remove by cutting.
the formation of a neoplasm.
1. a turning back of a part so as to form a duplication.
2. repetition of an experiment to ensure accuracy.
3. the process of duplicating or reproducing, as replication of an exact copy of a polynucleotide strand of DNA or RNA. See also deoxyribonucleic acid.
reduction of the number of leukocytes in the blood. It is a common manifestation of a number of diseases, especially those caused by viruses, by a severe inflammatory lesion that draws off large numbers of leukocytes, a consumption leukopenia, and by toxins which depress bone marrow function. See also radiation injury, pteridium aquilinum and stachybotris atra.
abnormal increase in volume of a tissue or organ caused by the formation and growth of new normal cells. Categorized as irregular, papillated, regular. See also myofiber hyperplasia.
inflammation of the parenchyma of the lung. It is often accompanied by inflammation of the airways and sometimes of the adjoining pleura. (more in book)
Organic compounds not soluble in water, but soluble in fat solvents such as alcohol. Lipids are stored in the body as energy reserves and are also important components of cell membranes.
a wound caused by rubbing or scraping the skin or mucous membrane. A 'skinned knee' and a 'rope burn' are common examples.
a sac or pouchlike depression or cavity.
introduction of pathogenic microorganisms, infective material, serum, or other substances into tissues of living organisms or into culture media; introduction of a disease agent into a healthy animal to produce a mild form of the disease, followed by immunity.
