In a relaxed cell, myosin is in a high energy state (cocked) but is unable to bind actin due to tropomyosin covering the myosin binding site. Atrial myofibers secrete a hormone (atrial natriuretic factor) from granules to cause loss of Na+ and H20 from kidney to reduce blood pressure. Some of these muscles help to express your emotions through gesticulation and facial expressions, while the heart beats more than 3.3 billion times over 80 years! increased ca2+ binds troponin, which displaces tropomyosin, thus exposing myosin binding site. Muscle tissue is classified into three types according to structure and function: skeletal, cardiac, and smooth ( Table 4.2 ).
