Document Summary
Tissue: group of cells that usually have a common origin in an embryo and function together to carry out specialized activities. Histology: the science that deals with the study of tissues. Pathologist: a physician who examines cells and tissues to help other physicians make accurate diagnoses. Epithelial tissue: covers body surfaces, lines hollow organs, body cavities, and ducts; it also forms glands. Allows the body to interact with both its internal and external environments. Connective tissue: protects and supports the body and its organs. Various types of connective tissue bind organs together, store energy reserves as fat, and help provide the body with immunity to disease-causing organisms. Muscular tissue: composed of cells specialized for contraction and generation of force. Muscular tissue generates heat that warms the body. Nervous tissue: detects changes in a variety of conditions inside and outside the body and responds by generating electrical signals called nerve action potentials that activate muscular contractions and glandular secretions.
