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.
The most common period symptom is the pain in your abdomen, back or thighs that is caused by menstrual cramps (often also referred to as period pain). You may have also heard of PMS. PMS (Pre-Menstrual Syndrome), also known as PMT (Pre-Menstrual Tension), can have a real negative effect on your mood.
