menstrual cycle

• The cervix is the lower part of the uterus that connects to the vagina.
• The ovaries are located on either side of the uterus and produce eggs (ova) and hormones such as estrogen, progesterone, and inhibin.
• Estrogen stimulates the growth of the endometrium lining of the uterus during the follicular phase.
• The ovaries are responsible for producing eggs (ova) and hormones such as estrogen and progesterone.
• Progesterone prepares the body for pregnancy by thickening the endometrial lining and maintaining it throughout the second half of the menstrual cycle.
• Inhibin prevents further release of FSH from the pituitary gland once ovulation has occurred.
• Inhibin regulates the production of FSH and LH from the pituitary gland.
• Progesterone prepares the body for pregnancy by thickening the endometrial lining and maintaining it if fertilization occurs.
• Follicle-stimulating hormone (FSH): Stimulates the development of an egg within one of the ovarian follicles.
• Ovulation occurs when the mature egg is released from its follicle and travels down the fallopian tube towards the uterus.
• If fertilization does not occur, progesterone levels decrease, causing the breakdown of the endometrial lining and bleeding during menstruation.
• Luteinizing Hormone (LH): Stimulates the maturation of an egg within one of the ovarian follicles and triggers its release at ovulation.
• Follicle Stimulating Hormone (FSH): Produced by the anterior pituitary gland, FSH stimulates the development of an egg within one of the ovarian follicles.
• Ovulation occurs when the mature egg is released from the ovary into the fallopian tube.
• Estrogen: Produced by the developing follicle and stimulates the growth of the uterine lining.
• Progesterone: Prevents further release of FSH from the pituitary gland once ovulation has occurred.
• The menstrual cycle consists of two phases: the follicular phase and the luteal phase.
