PY - 2018 T2 - The Big Picture: Medical Biochemistry AB - Movement and its regulation, on a microscopic and/or macroscopic scale, are essential for human life. Muscle, composed of actin, myosin, and a variety of structural and regulatory proteins, is one of the main cell/tissue types involved in this movement. Skeletal, cardiac, and smooth muscles offer a coordinated and regulated means to move the human body from place to place; interact with its surroundings; keep nutrients flowing to and waste products flowing from various cells; or move nutrients, blood, lymph, and other molecules. Specialized proteins and the means to provide energy for these processes have evolved for particular tissues and functions.
