  • Force Plate Analysis: - a way to measure the weight bearing ability of each leg as the animal walks on a tread mill. Each leg should bear weight evenly, a decrease in the force plate pressure means the pet isn't bearing full weight. It is used to measure improvements as well as to help detect subtle changes in gait. It is generally only used at the University level due to the expense of the equipment.

  • granuloma - a tumor-like mass or nodule of granulation tissue, with actively growing fibroblasts and capillary buds, consisting of a collection of modified macrophages resembling epithelial cells surrounded by a rim of mononuclear cells, chiefly lymphocytes, and sometimes a center of giant multinucleate cells; it is due to a chronic inflammatory process associated with infectious disease or invasion by a foreign body.
  • granulomatous - composed of granulomas
  • Applying Heat to a Pet: - Apply heat to the affected joint in a similar manner as you would your own. Heating pads should never be set above the lowest setting and should be covered with a towel to avoid burns. Care should be taken to prevent the pet from chewing the heating pad. Supervise the pet at all times while applying heat. 15 to 20 minutes a few times a day is generally helpful.

  • hyperactivity - excessive activity
  • hypersensitization - the process of rendering, or the condition of being abnormally sensitive.

  • intermittent - stopping and starting at intervals
  • intradermal - within the dermis
  • intramedullary - the marrow cavity of a bone
  • intramuscular (IM) - within the muscle
  • intravenous (IV) - within a vein
  • isthmus - a narrow connection between two larger bodies or parts, the narrower, thicker-walled portion of the uterine tube closest to the uterus, the constricted part of the uterus between the cervix and the body of the uterus.
  • KE Apparatus - an external fixator for a broken bone
  • ligate - to apply a ligature, any material, such as a thread or wire, used for tying a vessel or to constrict a part.
  • linea - in anatomy, a narrow ridge or streak on the surface of a structure, The tendinous median line on the anterior abdominal wall between the two rectus muscles or a rough longitudinal line on the back of the femur for muscle attachments.
  • mineralocorticoids - any of the group of corticosteroids, principally aldosterone, predominately involved in the regulation of electrolyte and water balance through their effect on ion transport in epithelial cells of the renal tubules.
  • mites - an arthropod of the order Acarina, except the ticks; they are minute animals, usually transparent or semitransparent, and may be parasitic on man and domestic animals, causing various skin irritations.
  • Nematode - larvae stage of the roundworm, a member of the class of helminths, many are parasites
