It is the submucosa layer, which connects the mucosa layer with the muscularis externa layer
Mechanisms that regulate smooth muscle contraction (independently of nerves or hormones) by which organs and tissues alter their own arteriolar resistances and blood flow are referred to as : Myosin and actin
<h3>Meaning of Myosin and actin </h3>
Myosin and actin are proteins that are found in all type of muscle tissue.
Smooth muscles (Heart) do not need nerves but it is an involuntary action, due to the presence of the myosin and actin, it work continuously.
Myosin and Actin are like a sliding filament in the muscle structure of the heart. they cause the heart to work continuously.
in conclusion, the Mechanisms that regulate smooth muscle contraction (independently of nerves or hormones) by which organs and tissues alter their own arteriolar resistances and blood flow are referred to as : Myosin and actin
