All muscle cells contain striations..

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.19 terms. akariaaxscr. Preview.
