Study Notes
Animal Tissues
- A tissue is a group of cells that share a common origin and work together for specialized functions.
- Histology is the study of tissues.
Four Types of Body Tissues
- Epithelial tissue covers body surfaces, lines body cavities and ducts, and forms glands. It interacts with the internal and external environment.
- Connective tissue protects, supports, and binds organs together. It stores energy, and contributes to immunity.
- Muscular tissue is specialized for contraction and generating force, including heat.
- Nervous tissue detects changes—inside and outside the body—and responds by generating nerve impulses, triggering muscular contractions and glandular secretions.
Cell Junctions
- Cell junctions are contact points between plasma membranes of tissue cells.
- Tight junctions fuse the outer surfaces of adjacent plasma membranes, sealing off passageways between them; they hold cells closely together, with no extracellular space.
- Gap junctions form tiny fluid-filled tunnels (connexons) between neighboring cells, facilitating communication.
- Adherence junctions create a dense layer of proteins on the inside of the plasma membrane, attaching to membrane proteins and microfilaments of the cytoskeleton, creating a belt that holds cells together.
- Desmosomes have plaques (a dense layer of proteins) that attach to transmembrane proteins extending into the intercellular space. They hold cells strongly.
