Hormones are chemical messengers produced by endocrine glands or tissues. They regulate various physiological processes and maintain homeostasis in the body. Here are some key points:
1. **Types**: Hormones can be classified into several types, including peptides, steroids, and amino acid derivatives.
2. **Function**: They regulate growth, metabolism, sexual function, mood, and more.
3. **Endocrine Glands**: Major glands include the pituitary, thyroid, adrenal, and pancreas.
4. **Regulation**: Hormone release is often controlled by feedback mechanisms involving the hypothalamus, pituitary gland, and target organs.
5. **Examples**:
- Insulin: regulates blood glucose levels.
- Testosterone and estrogen: control reproductive functions.
- Thyroid hormones: influence metabolism.
6. **Disorders**: Imbalances can lead to conditions like diabetes, hypothyroidism, or hyperthyroidism.
Understanding hormones helps in diagnosing and treating various health conditions effectively.
