hormones

• oestrogen inhibits FSH
• FSH stimulates oestrogen
• LH stimulates egg growth
• the hormones that produce and release mature eggs are follicle stimulating hormone and luteinising hormone
• Body temperature is monitored and controlled by the thermoregulatory centre in the brain.
• the four hormones:

  1. follicle stimulating hormone is produced in the pituitary gland and stimulates the ovaries to produce oestrogen
  2. oestrogen is produced in the ovaries and causes the lining of the uterus to grow, oestrogen stimulates the release of luteinising hormone
  3. luteinising hormone is produced by the pituitary gland and stimulates the release of eggs
  4. then finally progesterone is produced in the ovaries and maintains the lining of the uterus, progesterone inhibits the release of luteinising and follicle stimulating hormone
