A process whereby force is generated within smooth muscle tissue, resulting in a change in muscle geometry. This process occurs in the artery. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. The artery is a vessel carrying blood away from the heart. A process whereby force is generated within smooth muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. Smooth muscle differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. A process whereby force is generated within muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. A process whereby force is generated within tonic smooth muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. In the tonic smooth muscle, the muscle contraction occurs without an ordered sarcomeric structure. Tonic smooth muscle contraction occurs as a sustained continuous contraction. A process whereby force is generated within smooth muscle tissue, resulting in a change in muscle geometry. This process occurs in the proximal stomach. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. The proximal stomach, composed of the fundus and upper body, shows low frequency, sustained tonic contractions that are responsible for generating a basal pressure within the stomach.
