Name just 5 famous hormones from the ovary, and their roles (2). List some primary, secondary.and how they connect to the hormones like estrogen is linked with secondary sex characteristics. DO not use (oocyte/egg).
Ovaries secrets-
1. Estrogen - promotes growth of ovarian follicle. Prepares uterus for fertilization. Responsible for development of secondary sēxual characters. Have osteoclastic activity.
2. Progesterone- promotes secretory activity of uterine endometrium. It is concerned with final preparation of uterus for pregnancy and breasts for lactation.
3. Inhibin- secreted by granulosa cells. It inhibits FSH secretion through feedback mechanism.
4. Relaxin- secreted by maternal ovary (corpus luteum) . It helps labor by softening the cervix and loosening the ligaments of symphysis pubis. Dilates the cervix.
5. Androgen- small quantities is produced by ovaries. This androgen- is converted into estrogen.
Estrogen and progesterone are primary and main hormones. Rest are secondary.
Estrogen is the main hormone responsible for secondary sexúal characters. Inhibin- controls estrogen production by inhibiting it's release. By feedback mechanism, it reduces production of GnRH ,thus FSH is also reduced which eventually reduces estrogen.
