We'll look closer at smooth muscle contraction. (greek.doctor)
Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle . (wikidoc.org)
Diltiazem produces its antihypertensive effect primarily by relaxation of vascular smooth muscle and the resultant decrease in peripheral vascular resistance. (nih.gov)
and therefore reduce vascular smooth muscle tone. (pharmacology2000.com)
Hormones can also influence smooth muscle function. (britannica.com)
Among their most important sites of action are bronchial and uterine smooth muscle. (britannica.com)
RESULTS: Storage of rat aorta for 24 hours in genuine Euro-Collins solution almost abolished smooth muscle function, and severe edema was found in the endothelial cells. (lu.se)
However, if calcium was added, the rat aorta could be stored for 24 hours without affecting smooth muscle function, and endothelium-dependent relaxation was only slightly reduced. (lu.se)

8 Changes in collagen or elastin can contribute to an increase in SBP by as much as 6 to 7 mmHg per decade and result in the isolated SBP that affects about two-thirds of patients over the age of 60 years. (uspharmacist.com)

10 This may lead to an increase in the bioavailability of medications that undergo a high first-pass effect. (uspharmacist.com)
