Adhesion

    A band of scar tissue that joins normally separated internal body structures, most often after surgery, inflammation, or injury in the area.

RELATED TERMS
--------------------------------------

Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.

Surgery
Treating diseases or other medical conditions by operating on a patient to remove or repair parts of the body.

Inflammation
A reaction to an injury to the body - by infection, chemicals or physical agents. The symptoms can be - depending on the location of the injury- redness, swelling, heat and pain. The purpose of the inflammation is to dilute and destroy the agent causing the inflammation. To do this, the immune system starts a cascade of actions that causes active cells to gather at the affected location. It is these cells and fluids that cause the redness, swelling, heat and pain.

Injury
Injury is damage or harm caused to the structure or function of the body caused by an outside agent or force, which may be physical or chemical.



SIMILAR TERMS

Adheren, Zonula
Anchoring points where the CYTOSKELETON of neighboring cells are connected to each other. They are composed of specialized areas of the plasma membrane where bundles of MICROFILAMENTS attach to the membrane through the transmembrane linkers, CADHERINS, which in turn attach through their extracellular domains to cadherins in the neighboring cell membranes. In sheets of cells, they form into adhesion belts (zonula adherens) that go all the way around a cell.

Adherence Reaction, Immune
A method for the detection of very small quantities of antibody in which the antigen-antibody-complement complex adheres to indicator cells, usually primate erythrocytes or nonprimate blood platelets. The reaction is dependent on the number of bound C3 molecules on the C3b receptor sites of the indicator cell.

Adhesive capsulitis
"Constant severe limitation of the range of motion of the shoulder due to scarring around the shoulder joint. Adhesive capsulitis is an unwanted consequence of rotator cuff disease -- damage to the rotator cuff, the set of four tendons that stabilize the shoulder joint and help move the shoulder in diverse directions. Diabetes is also a risk factor for adhesive capsulitis. The affected joint is characteristically painful and tender to palpation. Physical therapy and corticosteroid injections (a ""cortisone shot"" into the joint) are often helpful. Surgery is reserved for more advanced cases. Also called a ""frozen shoulder"" because of loss of the ability to move the shoulder in all directions."
