Explanation / Answer
26. Menopause is characterized by low estrogen levels in plasma. As the age increases the level of estrogen production decreases. C
27. The FSH secretion is inhibited by estrogen. This mechanism is called reverse feedback. A
28. During the proliferative phase estrogen and FSH induce formation of more FSH receptors on granulosa cells. C
29.increased pulses of Gnrh starts the puberty in males. A
30. Stimulation of vagus nerve regulate the function of the stomach by increasing secretion of pepsinogen, increasing histamine, increasing motility so all the options are correct. E
