Apical Surface
one free (unattached) surface or edge on the membrane.
Basement Membrane
a thin layer of extracellular material to which epithelial cells are attached in mucosa surfaces.
Cartilage
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.
Connective tissue
a primary tissue; form and function vary extensively. Functions include support, storage, and protection.
Edema
an abnormal accumulation of fluid in body parts or tissues; causes swelling
Endocrine Gland
ductless gland that empty hormonal products directly into the blood.
Epithelium
: one of the primary tissues; covers the surface of the body and lines the body cavities, ducts, and vessels.
Extracellular Matrix
nonliving material in connective tissue consisting of ground substance and fibers that separate the living cells.
Fibrosis
involves repair by dense fibrous connective tissue by the formation of scar tissue.
Gland
an organ specialized to secrete or excrete substances for further use in the body or for elimination.
Goblet Cell
individual cells (simple glands) that produce mucus.
Granulation Tissue
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.
Mucosae/mucous membrane
membrane that forms the linings of body cavities open to the exterior (digestive, respiratory, urinary, and reproductive tracts).
Muscle Tissue
highly specialized to contract or shorten, to produce movement. Three types of muscle tissue, skeletal, cardiac and smooth(visceral).
Nervous Tissue
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.
Neuroglia
the nonneuronal tissue of the central nervous system that performs supportive and other functions; also called glia.
Secretion
(1) the passage of material formed by a cell to its exterior; (2) cell product that is transported to the cell exterior.
Serous Membrane
membrane that lines a cavity without an opening to the outside of the body (except for joint cavities, which have a synovial membrane); serosa.
Tendon
cord of dense fibrous tissue attaching a muscle to a bone
Tissue
a group of similar cells specialized to perform a specific function; primary tissue types are epithelial, connective, muscle, and nervous tissues.
Atrophy
a reduction in size or wasting away of an organ or cell resulting from disease or lack of use.
Carcinogens
Cancer causing agents
Hyperplasia
abnormal increase in number of cells
Metastasis
the spread of cancer from one body part or organ into another not directly connected to it.
Neoplasm
an abnormal growth of cells. Sometimes cancerous
Tumor
Benign: not malignant An abnormal mass of cells that remains at its original site of the tumor in the body.
Malignant Tumor
life-threatening, pertains to neoplasms that spread and lead to death, such as cancer.
