shoulder joint, the ball and socket articulation of the humerus with the scapula. The joint includes eight bursae and five ligaments, including the glenoidal labrum that deepens the articular cavity and protects the edges of articulating bones. It is the most mobile joint in the body. Also called humeral articulation.
It is common for young women to have irregular periods when they first begin to menstruate. This means that ovulation (when a womanâs body makes eggs) may not happen for a few months or even for a few years. So you may not have menstrual cramps when you first begin your period. After one, two, or three years, when your hormonal system is more mature, you might have more severe menstrual cramps.
Menstrual cramps are not the same as PMS. Symptoms of PMS such as bloating, weight gain, and moodiness happen before a womanâs period begins, and get a lot better when her period starts.On the other hand, with dysmenorrhea, cramps usually get worse the first day or two of a womanâs period and have a different cause and treatment.enstrual cramps are caused by uterine contractions (when your uterus tightens and relaxes allowing blood to leave your uterus). The lining of your uterus releases special chemicals called âprostaglandins.â These substances can increase the intensity of the contractions, especially if the levels rise.
