You and your group will be responsible for putting together a defensive presentation of an endocrine gland. You and your group will be giving this presentation during class. Your presentation must include: · A picture(s) of the gland showing its shape and location in the human body. · The hormone(s) produced by your endocrine gland.
 * Task:**

in in the overies two hormones prodused are oestrogen and progesterone which regulate the growth and functioning of sex organs for sexual reproduction ([]) oestrogen promotes development of female secondary sexual characteristics [] Estradiol is a hormone, often called the "female" hormone but also present in males it represents the major estrogen in humans. Critical for sexual functioning, estradiol also supports bone growth. Estradiol, like other sex steroids, is derived from cholesterol which is converted into androstenedione. Androstendione is then either converted to testosterone which in turn undergoes aromatization to estradiol, or, alternatively, androstendione is aromatized to estrone which is converted to estradiol. During the reproductive years most estradiol in women is produced by the granulosa cells of the ovaries []

· The stimulus that tells your gland to produce hormones.

follicle-stimulating hormone FSH and luteinizing hormone LH influance the overies to prduce ovum (eggs) witch in the case of pregnacy are firtielized by sperm and turnes in to the fetus. after seven days of ovulation the production of ostrogen and progesterone decrece witch this results in shedding of the endomentrium as mentrual bleeding 11-16 days after ovulation due to the rise of FSH witch rises beyond the threshold limit and starts producing follicals after a few days of growth it secrets estradiol in to the blood stream that goes to the typothalmus to signal that the threshold has been reached [] []

· The control mechanism that tells your gland to stop producing hormones. · The function(s) of the hormone(s) produced by your gland. What are the target organs/cells and how does the message carried by the hormone help maintain homeostasis. **This is probably the most important part of your presentation.**
