the periodic discharge of blood, tissue fluid, mucus, and epithelial cells form the uterus; it usually lasts for 5 days; it is caused by a sudden reduction in the levels of estrogens and progesterone; also called the menstrual phase or menses
For a few days each month a woman will bleed from her vagina. This bleeding time is called menstruation and can last 2-7 days. Menstruation will happen when a girl begins to mature into adulthood, anywhere from age 9-16. Once a girl begins menstruating, the bleeding will usually return every 20 to 40 days. Slang: period, visitor, friend, that time of the month, the curse.
A periodic vaginal flow of bloody mass and liquid occurring about once a month and lasting 3-5 days which carries out with it the unfertilized ovum from the uterus. It is immediately after the period that the female is normally the most receptive to sexual activity
the periodic flow of blood and cells from the lining of the womb, occurring about every 28 days. Menstruation commences and continues, unless interrupted by pregnancy, until the menopause, which occurs around the age of 50.
the monthly discharge of blood from the uterus of nonpregnant women from puberty to menopause; "the women were sickly and subject to excessive menstruation"; "a woman does not take the gout unless her menses be stopped"--Hippocrates; "the semen begins to appear in males and to be emitted at the same time of life that the catamenia begin to flow in females"--Aristotle
Periodical cycle in women wherein once a month an egg is released from the ovary, and the uterine wall is thickened to prepare for the fertilized egg to settle in it. If fertilization does not occur, then for 3-6 days the uterine lining sheds with discharge of blood.
(or menstrual period, monthly period) Periodical cycle in women in which an egg is released from the ovary once a month, and the uterine wall is thickened to prepare for the fertilized egg to settle in it. If fertilization does not occur, then the uterine lining is shed with discharge of blood after 3-6 days. Menstruation starts during adolescence, mostly between the ages of 10-15, and ends between the ages of 45-55.
The periodic blood that flows as a discharge from the uterus. Also called menorrhea, the time during which menstruation occurs is referred to as menses. The menses occurs at approximately 4 week intervals to compose the menstrual cycle.
The process in which the uterine endometrium breaks down and sheds cells, resulting in bleeding; occurs approximately once a month. The first day marks the beginning of the menstrual and ovarian cycles. PICTURE
also called a period. The menstrual cycle is the monthly process of shedding the lining of the uterus, and it happens when an egg (ovum) has not been fertilised by a sperm. Bleeding can be quite light or heavy, and either pads or tampons can be used to soak up the blood. Periods usually start sometime between 9 and 16. For some young women the first periods may be quite irregular. It is possible to become pregnant during a period if a woman has unprotected sexual intercourse, and contraception should always be used if pregnancy is not planned.
The monthly period or menstrual bleeding. During menstruation, the extra blood and tissue that built up inside the uterus during the menstrual cycle is expelled through the vagina, usually over a period of 3-7 days.
a cyclical process of the endometrium shedding its lining, along with discharge from the cervix and vagina, from the vaginal opening. This process results from the mature egg cell (ovum) not being fertilized by a sperm cell as it travels from one of the ovaries down a fallopian tube to the uterus, in the process called ovulation.
Menstruación a discharging of blood, secretions, and tissue debris from the uterus that recurs in nonpregnant human and other primate females of breeding age at approximately monthly intervals and that is considered to represent a readjustment of the uterus to the nonpregnant state following proliferative changes accompanying the preceding ovulation un proceso cíclico de exfoliación del revestimiento del endometrio, acompañado de flujo del cuello del útero y la vagina, desde la abertura de la vagina. Este proceso sucede cuando el espermatozoide no fertiliza el óvulo (gameto) maduro, mientras éste viaja desde uno de los ovarios, por la trompa de Falopio, hacia el útero, en el proceso llamado ovulación.
Discharge of blood and tissue from the lining of the uterus through the vagina for about 3 to 7 days each month. Occurs during the years from puberty to menopause, when a women is not pregnant. Also called a "period."
pain (1) - lower abdominal and pelvic pain that is associated with menses, the cyclic, physiologic discharge through the vagina of blood and mucosal tissues from the non-pregnant uterus, it is under hormonal control and normally recurs, usually at approximately four week intervals, in the absence of pregnancy during the reproductive period (puberty through menopause) of the female of the human and a few species of primates. It is the culmination of the menstrual cycle. Recurrent monthly menstrual pains (not explained by other causes) are often referred to as primary dysmenorrhoea.
The monthly shedding of the endometrium. Menstruation is the part of a woman's menstrual cycle where the endometrium (lining of the uterus) is shed, resulting in discharge of blood. Menstruation occurs each month if the egg released at ovulation is not fertilized. It occurs from menarche during puberty until menopause.
A recurring cycle (beginning at menarche and ending at menopause) in which the endometrial lining of the uterus prepares for pregnancy. If pregnancy does not occur the lining is shed in response to stimulation from estrogen and progesterone.
a monthly process (except during pregnancy) that involves a discharge of bloody fluid from the uterus through the vagina; the discharge contains tissue shed from the endometrium (the lining of a woman's uterus) during the reproductive cycle.
Menstruation is the part of the menstrual cycle in which the uterine lining (endometrium) is shed. Menstrual cycles occur exclusively in humans and other great apes. The females of other mammalian species experience an oestrus, in which the endometrium is reabsorbed by the animal at the end of its reproductive cycle.
