Which one of the following statements is incorrect about menstruation?
-
- During normal menstruation about 40 ml blood is lost
- The menstrual fluid can easily clot
- At menopause in the female, there is especially abrupt increase in gonadotropic hormones
- The beginning of the cycle of menstruation is called menarche
Correct Option: B
In human female, the periodic discharge of blood, mucus and cellular debris from uterine wall from non-pregnant women of sexual maturity is known as menstrual cycle. Few hours before the start of mensuration, the spiral arterioles constrict one by one resulting into the blanch mucosa. The mucosa shrinks and the death of the blood deprived tissues takes place. Blood clotting doesn’t occur due to presence of fibrinolysin.
