Vascular smooth muscle refers to the particular type of smooth muscle found within, and composing the majority of the wall of blood vessels. Vascular smooth muscle is innervated primarily by the sympathetic nervous system through adrenergic receptors (adrenoceptors). The three types present are: alpha-1, alpha-2 and beta-2 adrenergic receptors . The main endogenous agonist of these cell receptors is norepinephrine (NE).

WebSmooth muscle is also found lining our vessels whenever we need to vasoconstrict, or narrow those vessels. So there's also that smooth muscle there. So we don't think …

WebSmooth muscle contractions are involuntary movements triggered by impulses that travel through the autonomic nervous system to the smooth muscle tissue. The arrangement of cells within smooth muscle tissue allows for contraction and relaxation with great elasticity. WebThe membrane is richly innervated and vascularized, and it contains plenty of lymphatic vessels; it is an elastic tissue with smooth muscular cells, fibroblasts and elastin. 55 There is a hypothesis that this membrane can act as an elastic brake for the repositioning of the esophagus with breathing, thanks to its elastic hysteresis, helping to manage the anti …

WebYour somatic nervous system is a subdivision of your peripheral nervous system, which is all of your nervous system except your brain and spinal cord. Your somatic nervous system allows you to move and control muscles throughout your body. It also feeds information from four of your senses — smell, sound, taste and touch — into your brain.
