Document Summary
Biopsy- procedure that examines the tissue (surgically or needle) Tissue is formed by a group of cells (over 200 different types of cells) from the embryonic origin. Tissues are influenced by the extracellular environment and the connections of each cell type. Four major families of tissues: epithelial tissue, connective tissue, muscular tissue, nervous tissue. Cover body surfaces and lines hollow organs and cavities/ducts and glands. Connective tissue: protect/support the body and its organs. Bind organs together, store energy reserves as fat, provide body with immunity to disease causing organisms due to the different immunological cell types in this tissue. Contraction and generation of force lead to the movement of the body. Main cell types in nervous tissue: neurons and glial cells. Create a variety of conditions inside and outside the body that will respond by generating electrical signals that activate muscle contraction or the secretion of glands.
