GnRH, a hypothalamic hormone, needed in reproduction, acts on:
1. | Anterior pituitary gland and stimulates secretion of LH and FSH. |
2. | Posterior pituitary gland and stimulates secretion of oxytocin and FSH. |
3. | Posterior pituitary gland and stimulates secretion of LH and relaxin. |
4. | Anterior pituitary gland and stimulates secretion of LH and oxytocin. |
Hypersecretion of Growth Hormone in adults does not cause further increase in height, because?
1. | Epiphyseal plates close after adolescence. |
2. | Bones lose their sensitivity to Growth Hormone in adults. |
3. | Muscle fibres do not grow in size after birth. |
4. | Growth Hormones become inactive in adults. |
