Vasodilation (Overview)

Vasodilation refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, particularly in the large veins, large arteries, and smaller arterioles. The process is essentially the opposite of vasoconstriction, which is the narrowing of blood vessels.

Can you tell me about epinephrine stimulates a1 and b2 receptors. Does this lead to both vasoconstriction and vasodilation?

Adrenergic receptors: Hi. Epi stimulates vascular alpha-1 and beta-2 receptors, so yes, there is both vasoconstriction & vasodilation (so you see pulse width widen). Epi also stimulates cardiac beta-1 receptors and speeds up the heart rate. Not a question we commonly see...what makes you ask? Do you have a pheo? Good luck? ...Read more

Would alcohol cause vasodilation in the brain as it causes vasodilation in the body?

Not really: You mean, "Does your brain have that cute little red nose and rosy cheeks" appearance?

That is because BP within the confines of the brain are EXTREMELY tightly controlled. ...Read more

Ergometrime n oxytocine used together for postpasturm bleeding. But oxytocin causes vasodilation while erg. Cause vasoconstrict? So how they work?

After stretching to an incredible size (from normal), it then contractss or tightens upon itself to close the large blood vessels developed during pregnancy to prevent excessive bleeding after childbirth. Oxytocin stimulates and enhances this contractile activity ergotamine also causes uterine contractions as well as blood vessel constriction, reducing bleeding. ...Read more
