Which hormone is NOT secreted by the anterior pituitary gland?

What is the primary function of parathyroid hormone?

Which hormone is primarily responsible for sodium reabsorption in the kidneys?

Which statement regarding calcium homeostasis is NOT accurate?

Which of the following hormones is released by the anterior pituitary gland?

What is the primary role of aldosterone in the body?

Which of the following is true regarding type I diabetes?

Hormone Receptors and Actions

FSH and HCG are hormones.
Steroid hormone receptors are located within the cytoplasm.
Peptide hormones activate second messengers.
Receptors for steroid hormones are located in the cytoplasm.

Pituitary Hormones

Melanocyte-stimulating hormone, thyroid-stimulating hormone, and growth hormone are released by the anterior pituitary.
Gonadotrophin-releasing hormone is not released by the anterior pituitary.
Adrenocorticotropic hormone stimulates the adrenal cortex to produce hormones.

Hormone Actions and Target Tissues

Parathyroid hormone maintains adequate calcium levels in the blood.
Aldosterone stimulates sodium reabsorption in the kidneys.
Type 1 diabetes can be caused by a lack of beta cells or functional insulin receptors in the body.
Type 1 diabetes cannot be managed by diet and exercise alone.
Individuals with type 1 diabetes may lack beta cells or have non-functional insulin receptors.

Calcium Homeostasis

Calcitonin, parathyroid hormone, and 1,25-dihydroxycholecalciferol are vital for calcium homeostasis.
Glucagon is not a major player in calcium balance.
Monitoring extracellular calcium levels is a crucial aspect of the parathyroid's role.
Inhibiting osteoclast activity can help normalize high extracellular calcium levels.
Calcitonin and parathyroid hormone have opposing effects on extracellular calcium.
1,25-dihydroxycholecalciferol and parathyroid hormone have opposing effects on extracellular calcium.

Dive into the fascinating world of hormones and their receptors. This quiz covers key concepts including the functions of various hormones like FSH, HCG, and how they interact with target tissues. Test your knowledge on pituitary hormones and calcium homeostasis, and understand the physiological roles these hormones play in the body.
