For muscles to contract there needs to be an adequate supply of ATP within the cell. ATP is generated in part by a supply of glucose and oxidative phosphorylation. An inadequate supply of blood will not provide enough oxygen to keep up with the energy demands of contraction.

Why do females cramp when they are on they period?
The uterus is a muscle. During menses it contracts to expel menstrual blood. This is a mild from of the contraction it does to push out a baby. The contraction can press against a blood vessel and cut off the blood supply. This pinching off of the blood supply causes the cramping.
Which main factor allows muscle to sustain contraction even during time when the blood supply is low?
myoglobin
Why do girls have cramps during periods?
The uterus is a muscle. During menses it contracts to expel the uterine lining and menstrual blood. This is a mild from of the contraction it does to push out a baby. The contraction can press against a blood vessel and cut off the blood supply. This pinching off of the blood supply causes the cramping.Answer 2:I believe it's because of the shedding of the uterus lining.
How decreased blood supply effect muscle activity?
Decreased blood supply in the muscle can cause anoxia then paralysis.
Which tissue has direct blood supply epithelial connective muscle or nervous?

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
Contraction of the smooth muscle in arterioles would decrease blood pressure?
No it would increase BP, as contraction of the smooth muscle in the arterioles will make the lumen (holes) of the arterioles smaller, restricting blood flow.
Where does the heart muscle receives its blood supply from?
The heart muscle is supplied by blood vessels called coronaries.
What nuclei regulates the contraction of smooth muscle in blood vessel walls?
vasomotor center
What is blood supply of cardiac muscle?
Coronary arteries
Arteries that supply the heart muscle with blood?
Yes.
