Study Notes
Endocrine System
- Hormones are important signaling molecules secreted by glands in the endocrine system, without ducts to carry them away, unlike exocrine glands.
- Major endocrine glands include:
- Brain: hypothalamus, pineal gland, pituitary gland
- Neck: thyroid, parathyroid
- Upper chest: thymus
- Above the kidneys: adrenal glands
- Near the stomach: pancreas
- Gonads: ovaries and testes
Glands and Hormones
- Glands may have both endocrine and exocrine functions, like the pancreas.
- Different classes of hormones can be derived from biomolecules like:
- Amino acids
- Polypeptides
- Lipids
- Hormones bind to specific target cells and elicit various responses like:
- Increasing mitosis rate
- Preparing enzymes for action
Hypothalamus-Pituitary Complex
- The hypothalamus-pituitary complex is crucial in regulating many other endocrine glands.
- The pituitary gland secretes hormones like:
- Oxytocin
- Growth hormone
Endocrine Disorders
- Disorders like hypothyroidism can result from underactive glands like the thyroid.
- Symptoms of hypothyroidism include:
- Extreme fatigue
- Slowed heart rate
- Due to insufficient production of thyroid hormones.
