The hypothalamus uses neurohormones to stimulate release of other hormones. What advantage does this have in hormone release?
What will be an ideal response?
The use of tropic hormones allows a small signal from the hypothalamus to be amplified by the next hormone secreted. In this way, a few molecules of a tropic hormone may result in a thousand fold increase of the hormone from the stimulated endocrine gland. This allows the brain to exert a strong regulatory control over hormonal secretion from a small neural region (the hypothalamus).
