Properties of muscle cells
WebMost cells in the body make use of charged particles, ions, to build up a charge across the cell membrane. Previously, this was shown to be a part of how muscle cells work. For skeletal muscles to contract, based on excitation–contraction … WebSkeletal muscle tissue is composed of long cells called muscle fibers that have a striated appearance. Muscle fibers are organized into bundles supplied by blood vessels and innervated by motor neurons. 2. The Walls of Many Human Organs Contract and Relax Automatically Smooth muscle is found in the walls of hollow organs throughout the body.
