Regulation of hormone levels 1- Regulation of hormone synthesis and secretion: The release of hormones is stimulated by changes in the environment or physiologic state or by stimulatory hormone from another tissue that acts on the cells that release the hormone for example: •A decrease in blood pressure initiates a sequence of

Lecture objectives. Define the terms hormone, target cell, and receptor. Understand the chemical nature of different classes of hormones and how this determines their mechanism of action on target cells. Contrast membrane bound and intracellular hormone receptors.
The endocrine system produces hormones that are instrumental in maintaining homeostasis and regulating reproduction and development. A hormone is a chemical messenger produced by a cell that effects specific change in the cellular activity of other cells (target cells). Unlike exocrine glands (which produce substances such as saliva,
The document summarizes the endocrine system and its role in homeostasis. It describes three types of messenger molecules - local hormones, endocrine hormones, and neurotransmitters.
