Document Summary
Week 11 screencast integrating cells into tissues. Organization of cells in multicellular organisms: cells take on specific structures and functions, for example, Myocytes take on an elongated shape and possess multiple nuclei. Use actin and myosin to contract and generate force: cells of a given type will often aggregate to form tissues. Multiple myocytes will aggregate to form a skeletal muscle fascicle: tissues will associate to form organs. Multiple muscle fascicles will aggregate with nerves, blood vessels and connective tissue to form a skeletal muscle (e. g. pectoralis major muscle: organs will associate to form organ systems. Skeletal muscles will associate with bones to form the musculoskeletal system: organ systems will associate to form an organism. Adhesion overview: the adhesion of cells to their neighbours and their surrounding environment is essential for tissue development, cells associate with one another through cell-cell adhesion interactions.
