Abstract. There are three types of muscle in the body: skeletal (the muscles used to move the skeleton), cardiac (the muscle in the heart), and smooth (the muscle used for unconscious things like digestions and continence). Each has specialised cell adaptations. ANP and BNP are released from cardiac muscle when it is placed under stress.plasma membrane of the muscle cell. myofibril. a long, filamentous organelle found within muscle cells that has a banded appearance. myofilament. actin-or myosin-containing structure. tendon. cordlike extension of connective tissue beyond the muscle, serving to attach it to the bone. fascicle. a discrete bundle of muscle cells.
