It also stimulates the ovaries to produce hormones including oestrogen 4 of 9 3) Luteinising Hormone (LH) Stimulates the release of eggs from the ovary 5 of 9 2) Oestrogen Secreted by the ovaries and inhibits the further production of FSH. 6 of 9 Stimulus Change in your environment 7 of 9 Central Nervous System (CNS) Where all information from the sense organs is sent and where reflexes and actions are coordinated, consists of brain and spinal chord only, 8 of 9 Receptors Group of cells which are sensitive to a stimulus 9 of 9
