Cardiac muscle cells appear striated or striped under a microscope ...Myocytes, sometimes called muscle fibers, form the bulk of muscle tissue. They are bound together by perimysium, a sheath of connective tissue, into bundles called fascicles, which are in turn bundled together to form muscle tissue. Muscles are composed of long bundles of Myocytes (Muscle fibers). Myocytes contain thousands of myofibrils.Relaxing skeletal muscle fibers, and ultimately, the skeletal muscle, begins with the motor neuron, which stops releasing its chemical signal, ACh, into the synapse at the NMJ. The muscle fiber will repolarize, which closes the gates in the SR where Ca ++ was being released. ATP-driven pumps will move Ca ++ out of the sarcoplasm back into the SR.Skeletal muscle cells are responsible for practically all movements that are under voluntary control. These cells can be very large (2–3 cm long and 100 μm in diameter in an adult human) and are often referred to as muscle fibers because of their highly elongated shape. Each one is a syncytium, containing many nuclei within a common cytoplasm.The other …Cardiac muscle is striated muscle that is present only in the heart.
