Apical Surface

one free (unattached) surface or edge on the membrane.

Atrophy

a reduction in size or wasting away of an organ or cell resulting from disease or lack of use.

Basement Membrane

a thin layer of extracellular material to which epithelial cells are attached in mucosa surfaces.

Carcinogens

Cancer causing agents

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.

Hyperplasia

abnormal increase in number of cells

Malignant Tumor

life-threatening, pertains to neoplasms that spread and lead to death, such as cancer.

Metastasis

the spread of cancer from one body part or organ into another not directly connected to it.

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).

Neoplasm

an abnormal growth of cells. Sometimes cancerous

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.

Tumor

Benign: not malignant An abnormal mass of cells that remains at its original site of the tumor in the body.
