Menstrual cycle is the cycle of changes that occurs in the uterus and ovary for the purpose of sexual reproduction. It is essential for the production of eggs and for the preparation of the uterus for pregnancy. The menstrual cycle occurs only in fertile female humans and other female primates.
In humans, the length of a menstrual cycle varies greatly among women (ranging from 25 to 35 days), with 28 days designated as the average length. Each cycle can be divided into three phases based on events in the ovary (ovarian cycle) or in the uterus (uterine cycle). The ovarian cycle consists of the follicular phase, ovulation, and luteal phase whereas the uterine cycle is divided into menstruation, proliferative phase, and secretory phase. Both cycles are controlled by the endocrine system and the normal hormonal changes that occur can be interfered with using hormonal contraception to prevent reproduction.
Premenstrual syndrome (PMS) or perimenstrual syndrome is a collection of emotional symptoms, with or without physical symptoms, related to a woman's menstrual cycle. While most women of child-bearing age (up to 85%) report having experienced physical symptoms related to normal ovulatory function, such as bloating or breast tenderness, medical definitions of PMS are limited to a consistent pattern of emotional and physical symptoms occurring only during the luteal phase of the menstrual cycle that are of "sufficient severity to interfere with some aspects of life". In particular, emotional symptoms must be present consistently to diagnose PMS. The specific emotional and physical symptoms attributable to PMS vary from woman to woman, but each individual woman's pattern of symptoms is predictable, occurs consistently during the ten days prior to menses, and vanishes either shortly before or shortly after the start of menstrual flow.
Two to ten percent of women have significant premenstrual symptoms that are separate from the normal discomfort associated with menstruation in healthy women.
Organized crime, Organised crime, and often criminal organizations are a group of terms which categorise transnational, national, or local groupings of highly centralized enterprises run by criminals, who intend to engage in illegal activity, most commonly for monetary profit. Some criminal organizations, such as terrorist organizations, are politically motivated. Sometimes criminal organizations force people to do business with them, as when a gang extorts money from shopkeepers for so-called "protection". Gangs may become disciplined enough to be considered organized. An organized gang or criminal set can also be referred to as a mob.
Other organizations like, States, the Army, Police, Governments and Corporations may sometimes use organized crime methods to conduct their business, but their powers derive from their status as formal social institutions. There is a tendency to distinguish organized crime from other forms of crimes, such as, white-collar crime, financial crimes, political crimes, war crime, state crimes and treason. This distinction is not always apparent and the academic debate is ongoing. For example, in failed states that can no longer perform basic functions such as education, security, or governance, usually due to fractious violence or extreme poverty, organised crime, governance and war are often complimentary to each other. The term Parliamentary Mafiocracy is often attributed to democratic countries whose political, social and economic institutions are under the control of few families and business oligarchs.
