- Write a summary on functions and mechanism of female sex hormones ? Or write a short note on function and mechanism of female sex hormone? Please write at your own words. Answer should be specific (8-10)lines.arrow_forwardWhich gland would logically make a hormone detected by a home pregnancy test? Posterior Pituitary gland Pineal Parathyroid Placentaarrow_forwardWhich of the following statements regarding pituitary hormones is FALSE? Adrenocorticotropic hormone, released by the anterior pituitary, targets the adrenal medulla to increase cardiac output and blood flow. Luteinizing hormone, an anterior pituitary hormone, triggers ovulation of an egg from the ovary and causes the ruptured follicle to produce progesterone and some estrogens. Hyposecretion of follicle-stimulating hormone or luteinizing hormone leads to sterility in both males and females. O The hypothalamus makes oxytocin and antidiuretic hormone, which are transported the posterior pituitary for storage.arrow_forward
- Drag and drop the missing words from the list below to complete the following sentences. Please note, the colour of the answer text must match the answer box. For example, the white texts can only be dragged into a white coloured box. Also, words may be used more than once. increased levels of estrogen and progesterone will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to ( negative, positive, increase, decrease), ( LH, FSH, GnRh, LH AND FSH) production. This normally occurs during the ( FOLLICULAR STAGE, LUTEAL STAGE ) Decreased levels of estrogen and progesterone will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to ( negative, positive, increase, decrease), (LH, FSH, GnRh, LH AND FSH) production. This normally occurs during the ( FOLLICULAR STAGE, LUTEAL STAGE ). Extremely high levels of estrogen near the end of the follicular phase will result in ( negative,…arrow_forwardUse the following list of reproductive hormones and structures to answer the next question. FSH LH Estrogen Progesterone GnRH Follicle Corpus luteum Hypothalamus Anterior pituitary Gonadotropic hormones are released by the anterior pituitary to regulate the functions of the gonads (testis in males and ovaries in females). Use the list to select a gonadotropic hormone, the structure it stimulates in the ovaries, and the main hormone that is released by that structure as a result. (There are two possible answers.) ____ Gonadotropic hormone ____ Structure it acts on ____ Main hormone releasedarrow_forwardUse the following information to answer the following questions.
