Summary Introduction

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 the response of other tissues or cells. Hormones bind only to specific cells based on their corresponding receptors present on cells. Hormones act through chemical signals.
