To discuss:
Hyposecretion and hypersecretion effects of growth hormone, and their difference between adult and childhood onset.
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 and act through chemical signals. They regulate growth, development, blood pressure,
