a reduction in size or wasting away of an organ or cell resulting from disease or lack of use.
a thin layer of extracellular material to which epithelial cells are attached in mucosa surfaces.
white, semiopaque connective tissue. Less hard and more flexible than bone. Has abundant collagen fibers hidden by a rubbery matrix with a glassy, blue white appearance.
a primary tissue; form and function vary extensively. Functions include support, storage, and protection.
: one of the primary tissues; covers the surface of the body and lines the body cavities, ducts, and vessels.
nonliving material in connective tissue consisting of ground substance and fibers that separate the living cells.
an organ specialized to secrete or excrete substances for further use in the body or for elimination.
Connective tissue a delicate pink tissue composed largely of new capillaries that grow into the damaged area from undamaged blood vessels nearby. Also contains phagocytes that eventually dispose of the blood clot and connective tissue cells(fibroblasts) that produce the building blocks of collagen fibers(scabs) to permanently bridge the gap.
life-threatening, pertains to neoplasms that spread and lead to death, such as cancer.
the spread of cancer from one body part or organ into another not directly connected to it.
membrane that forms the linings of body cavities open to the exterior (digestive, respiratory, urinary, and reproductive tracts).
highly specialized to contract or shorten, to produce movement. Three types of muscle tissue, skeletal, cardiac and smooth(visceral).
Tissue made up of cells called neurons. A body tissue that carries electrical messages back and forth between the brain and every other part of the body.
the nonneuronal tissue of the central nervous system that performs supportive and other functions; also called glia.
(1) the passage of material formed by a cell to its exterior; (2) cell product that is transported to the cell exterior.
membrane that lines a cavity without an opening to the outside of the body (except for joint cavities, which have a synovial membrane); serosa.
a group of similar cells specialized to perform a specific function; primary tissue types are epithelial, connective, muscle, and nervous tissues.
