Unknown Story
Text z Príbehu
- The brain generates gonadotropin-releasing hormone during the menstrual cycle.
- The body's equilibrium and hormone production are controlled by the hypothalamus.
- GnRH promotes follicle-stimulating hormone and luteinizing hormone synthesis in the pituitary gland.
- Hormones are secreted into the circulation by the pituitary gland to serve as informational messengers to other cells. To control how the organs work, the pituitary glands transmit signals.
- Amid each menstrual cycle, the ovaries release eggs into the female reproductive system. The cells in the follicles quickly divide as the eggs mature and create the hormone estrogen.
- Throughout the middle of the menstrual cycle, estrogen levels increase. An egg is released in response to this. Following ovulation, this amount then rapidly declines.
- During ovulation, the hormone progesterone gets the uterus ready for pregnancy. Progesterone levels start to decline since there are no eggs to fertilise.
- The uterus' lining develops during ovulation and thickens in preparation for a potential fertilised egg. The body will expel the lining if the egg is not fertilised. The menstrual blood will then leave your body through the vagina after leaving the uterus and travelling to the cervix.
- The menstrual cycle is an illustration of a negative feedback loop because the brain and pituitary gland produce less hormones as a result of the rising hormone levels.
- Reduced estrogen and progesterone levels in a woman's body after the conclusion of her last menstrual cycle act as the stimulation for the menstrual cycle.
