Hormones

Hormones are special chemical messengers in the body that are created in the endocrine glands. They are released into the bloodstream and have specific effects on different parts of the body. Hormones play a crucial role in regulating various bodily functions, including growth and development, metabolism, sexual function, and mood.

Types of Hormones

There are several types of hormones, including:

• Steroid Hormones: These are derived from cholesterol and include hormones such as estrogen, progesterone, and testosterone.
• Peptide Hormones: These are made up of amino acids and include hormones such as insulin and growth hormone.
• Amino Acid-Derived Hormones: These are derived from amino acids and include hormones such as epinephrine and thyroxine.

Functions of Hormones

Hormones have diverse functions in the body, including:

• Regulating Metabolism: Hormones such as insulin and glucagon help regulate blood sugar levels and metabolism.
• Controlling Growth and Development: Growth hormone and sex hormones play a key role in growth, development, and sexual maturation.
• Regulating Reproduction: Hormones such as estrogen and progesterone are involved in the menstrual cycle and pregnancy.
• Maintaining Homeostasis: Hormones help maintain a stable internal environment by regulating body temperature, fluid balance, and other physiological processes.
• Mediating Stress Responses: Hormones such as cortisol and adrenaline help the body respond to stress.
