sacromere
actin myosin
muscle
Contractile cells are the smooth muscle cells of the heart that... contract. They get their signal from the nodes within the heart, which spontaneously fire action potentials (because of leak channels).
sarcomere
series-elastic elements
Myofibrils
Sarcomere
(pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.
troponin
Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.
Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.
it is set by pacemaker cells located in the longitudinal smooth muscle layer.
