"Initiated by endothelial injury and caused by local and humoral mechanisms". Other helpers such as thromboxane, platelets releasing prosaglandin and neural reflexes all aid in vasoconstriction of the vessels.

An angiospasm is a spasm of a?
Blood vessel
What is the first step in hemostasis?
vascular spasm
What is local myogenic spasm?
Muscle Spasm, this would be referring to when a blood vessel is broken, the response to fix it would be vasoconstriction. A myogenic spasm would aid in the loss of blood by briefly constricting the muscle where the broken blood vessel is located.
What is a Vasospasm?
Vasospasm-- Narrowing of a blood vessel caused by a spasm of the smooth muscle of the vessel wall.
What is the first response in a blood vessel injury?
Vascular spasm
What is the root of vasospasm?
The term means a tightening of a blood vessel. Vaso-=vessel + spasm=constriction. The root of the word is vaso-
Will lymphedema cause spasm in the hand?
will low blood sodium cause spasms in the hands
Can a muscle strain or spasm result in a bruise?
Yes it can if the muscle fibres are ruptured
What causes hemifacial spasm?
The cause of hemifacial spasm has been linked to overactivity of the seventh cranial nerve nucleus that signals facial muscle movement. In other instances, hemifacial spasm may be caused by compression by a mass or abnormal blood vessel.
When you get a minor cut platelets in your blood stick to the wound cause threads to form a clot?
When you get a cut, the plateletes collect at the site to form a sticky plug. They secrete a chemical, serotonin, which causes the blood vessel to spasm and narrow, decreasing the flow of blood. It is what forms a scab.
What is the medical term meaning sudden contraction of a blood vessel?
Angiospasm is sudden contraction of a blood vessel. In contrast, vasoconstriction is the normal process of contraction of a blood vessel.VasoconstrictionAngiospasm
What is the process of hemostasis?
Homeostasis works to stop blood flow when there is a break in the blood vessel. First there is platelet plug formation where leukocytes of white blood cells stick and clot to block the blood from pouring out. Second there are vascular spasms caused by serotonin releases from the platelets and the blood vessel muscles spasm's work to decrease blood loss Lastly there is coagulation (most complicated), its where the injured tissues release thromboplastin and that reacts with PF3(aka phospholipids) to make a clotting cascade. Eventually prothrombin activator converts prothrombin to thrombin(an enzyme that really sticky) and thrombin and fibrinogen make fibrin which eventually forms a net (like a mesh) to clot blood
