8. Mention the difference between hypothyroidism and hyperthyroidism.
9. You have learnt that a characteristic feature of endocrine system is the
presence of feed back loops. By this what is meant if hormone A stimulates
gland ‘X’ to secrete hormone B, the production of ‘A’ could be modified
when the level of B changes in our blood. An example is the relation
between hormones LH and estrogen (E
2
). An old woman exhibits the
following features. High levels of LH in blood but low levels of E
2
 in the
blood. Another woman exhibits high level of LH in blood and also high
level of E
2
 in the blood. Where is the defect in both these women? Provide
suitable diagram to support this answer.
