Study Notes
Glucose/Blood Pressure Antagonistic Hormones
- Insulin and glucagon are antagonistic hormones that regulate blood glucose levels.
- Insulin is produced by beta cells located in the Islets of Langerhans (IOL) in the pancreas.
- Glucagon is produced by alpha cells within the same islets of the pancreas.
Functions of Insulin and Glucagon
- Insulin lowers blood glucose levels, promoting glucose uptake by cells.
- Glucagon raises blood glucose levels by promoting the release of glucose from liver stores.
Targets of Insulin and Glucagon
- Both hormones primarily target the liver and muscle tissues, influencing glucose metabolism.
Regulation Mechanism
- Insulin and glucagon maintain homeostasis by regulating glucose levels in the blood.
Calcium Blood Levels Antagonistic Hormones
- Calcitonin and parathyroid hormone (PTH) are responsible for regulating calcium blood levels antagonistically.
- Calcitonin is produced by the thyroid gland.
Functions of Calcitonin and PTH
- Calcitonin lowers calcium levels by promoting calcium storage in bones.
- PTH increases calcium levels by stimulating the release of calcium from bones.
Targets of Calcitonin and PTH
- Both calcitonin and PTH affect bone, intestine, and kidneys, which are critical for calcium homeostasis.
Regulation Mechanism
- Calcitonin and PTH work together to maintain calcium levels in the blood.
Origin of Hormones
- Calcitonin and PTH are both produced in the parathyroid gland.
- Glucagon and insulin are produced in the pancreas, emphasizing the role of different endocrine glands in hormone secretion.
