Periodic discharge of blood, mucus, and epithelia cell from the uterus
Menstruation
Is the beginning of menstruation to the beginning of the next menstruation
Menstrual cycle
Is the first menstruation in women
Menarche
Is a severe pain during menstruation
Dysmenorrhea
Is the complete bleeding at completely irregular interval
Metrorrhagia
Is the excessive bleeding during menstruation
Menorrhagia
Is the absence of menstruation leading to pregnancy
Amenorrhea
Is the end of menstruation/cessation of menstruation
A
Menopause
A female hormone that is produced by the ovaries. It helps control and guide sexual development, including the physical changes associated with puberty
Estrogen
A hormone that helps to regulate your cycle. But its main function is to help thicken the lining of the uterus to prepare for a fertilized egg.
Progesterone
The mean age for menarche
12.87 years or 1-3 years after breast budding
is actually the end of an arbitrary defined menstrual cycle
Menses
The menstrual phase varies in length for most women
Ave period: 5 days
Ave cycle: 28 days
Normal blood loss: 50cc
Is the hormonal process a woman’s body goes through each month to prepare for a possible pregnancy
Menstrual cycle
a sign that your body is working normally
Regular menstrual periods in the years between puberty and menopause
For menstrual cycle to be complete, all four structures must contribute their part. Therefore, inactivity of any parts results in an incomplete or ineffective cycle
-hypothalamus
-pituitary gland
-ovaries
-uterus
Produces GnRH or Gonadotropin Releasing Hormone to stimulate the anterior Pituitary gland
Hypothalamus
Secretes gonadotropins (FSH and LH): stimulates the ovary (estrogen and progesterone) - if estrogen/progesterone increase in blood vessels, this gives positive feedback to the hypothalamus to decrease all hormones
Anterior Pituitary Gland
After an upsurge of LH, the graafian follicle raptures and the ovum is set free from the ovary
Ovulation
After an upsurge of LH, the graafian follicle raptures and the ovum is set free from the ovary called ovulation and swept into an open end of a fallopian tube, the FSH has done its work and now decreases its amount. It occurs approximately on the 14th day before the onset of the next menstrual cycle.
Ovaries
The ovulation happens at the midpoint of a 28-day cycle
If the cycle is only 20 days long 20-14=6 day of ovulation not the 10th or middle day
What happens if conception does not occur?
the unfertilized ovum atrophies after 4 days and the corpus luteum remain for only 8-10 days and regresses. Stimulation from the hormones produced by the ovaries causes specific monthly effects on the uterus and uterine changes occur during the menstrual cycle
If conception occurs, the fertilized ovum implants on the endometrium of the uterus, the corpus luteum remains throughout
Uterus
Menstrual flow is composed of:
-blood from ruptured capillaries
-mucin from the glands
-fragments of the endometrial tissue
- the microscopic, atrophied, unfertilized ovum
