Introduction:
Hormones are chemical messengers secreted by the endocrine glands or neurosecretory cells into the extracellular fluids. The secreted hormones reach the target cells through the bloodstream, and they stimulate response of other tissues or cells. Hormones bind only to specific cells based on their corresponding receptors present on cells. They act through chemical signals. They regulate growth, development, blood pressure,
