Study Notes
Endocrine Glands Function
- Major role in hormone production and secretion.
- Regulate a variety of physiological processes including metabolism, growth, and mood.
Pancreas and Islet Cells
- Contains clusters of islet cells, known as the islets of Langerhans.
- These islet cells are essential for glucose regulation since they produce insulin and glucagon.
Adrenal Glands Histology
- Exhibit distinct histological features such as three layers: zona glomerulosa, zona fasciculata, and zona reticularis.
- Each layer produces different hormones like aldosterone, cortisol, and androgens, contributing to stress response and metabolism.
Factors Affecting Hormone Levels
- Hormone levels can be influenced by factors such as stress, diet, medications, and physical activity.
- Environmental triggers and health conditions also play a significant role in hormone fluctuations.
Importance of Regulating Hormone Levels
- Maintains homeostasis within the body, ensuring organs function properly.
- Imbalances can lead to various health issues, including diabetes, thyroid disorders, and adrenal insufficiency.
