Which hormone is primarily responsible for regulating blood sugar levels?

  1. Insulin

  2. Glucagon

  3. Epinephrine

  4. Thyroxine


Correct Option: A
Explanation:

Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels by allowing glucose to enter cells for energy production.

What is the primary function of the thyroid gland?

  1. Regulating metabolism

  2. Producing insulin

  3. Controlling blood pressure

  4. Maintaining electrolyte balance


Correct Option: A
Explanation:

The thyroid gland produces hormones that regulate metabolism, influencing energy expenditure, growth, and development.

Which hormone is responsible for stimulating the breakdown of glycogen into glucose?

  1. Insulin

  2. Glucagon

  3. Epinephrine

  4. Thyroxine


Correct Option: B
Explanation:

Glucagon is a hormone produced by the pancreas that stimulates the liver to break down glycogen into glucose, raising blood sugar levels.

What is the most common type of diabetes?

  1. Type 1 diabetes

  2. Type 2 diabetes

  3. Gestational diabetes

  4. Secondary diabetes


Correct Option: B
Explanation:

Type 2 diabetes is the most common type, characterized by insulin resistance and impaired insulin production, leading to high blood sugar levels.

Which hormone is responsible for regulating calcium and phosphate levels in the body?

  1. Insulin

  2. Glucagon

  3. Parathyroid hormone

  4. Thyroxine


Correct Option: C
Explanation:

Parathyroid hormone regulates calcium and phosphate levels in the body, maintaining bone health and preventing imbalances.

What is the primary function of the adrenal glands?

  1. Producing insulin

  2. Regulating blood pressure

  3. Controlling metabolism

  4. Producing sex hormones


Correct Option: B
Explanation:

The adrenal glands produce hormones like cortisol and aldosterone, which help regulate blood pressure, stress response, and electrolyte balance.

Which hormone is responsible for stimulating the release of growth hormone?

  1. Insulin

  2. Glucagon

  3. Growth hormone-releasing hormone

  4. Thyroxine


Correct Option: C
Explanation:

Growth hormone-releasing hormone is produced by the hypothalamus and stimulates the pituitary gland to release growth hormone, promoting growth and development.

What is the primary function of the pancreas in the endocrine system?

  1. Producing insulin and glucagon

  2. Regulating blood pressure

  3. Controlling metabolism

  4. Producing sex hormones


Correct Option: A
Explanation:

The pancreas produces insulin and glucagon, which are essential hormones for regulating blood sugar levels and maintaining glucose homeostasis.

Which hormone is responsible for regulating the menstrual cycle and ovulation?

  1. Insulin

  2. Glucagon

  3. Estrogen

  4. Thyroxine


Correct Option: C
Explanation:

Estrogen is a hormone produced by the ovaries and plays a crucial role in regulating the menstrual cycle, ovulation, and reproductive functions.

What is the primary function of the pituitary gland?

  1. Producing insulin

  2. Regulating blood pressure

  3. Controlling metabolism

  4. Producing growth hormone


Correct Option: D
Explanation:

The pituitary gland produces growth hormone, which is essential for growth and development, as well as other hormones that regulate various bodily functions.

Which hormone is responsible for regulating sleep-wake cycles?

  1. Insulin

  2. Glucagon

  3. Melatonin

  4. Thyroxine


Correct Option: C
Explanation:

Melatonin is a hormone produced by the pineal gland and plays a crucial role in regulating sleep-wake cycles and circadian rhythms.

What is the primary function of the hypothalamus in the endocrine system?

  1. Producing insulin

  2. Regulating blood pressure

  3. Controlling metabolism

  4. Producing growth hormone


Correct Option: C
Explanation:

The hypothalamus plays a crucial role in controlling metabolism, regulating body temperature, and releasing hormones that influence other endocrine glands.

Which hormone is responsible for stimulating the production of breast milk?

  1. Insulin

  2. Glucagon

  3. Prolactin

  4. Thyroxine


Correct Option: C
Explanation:

Prolactin is a hormone produced by the pituitary gland that stimulates the production of breast milk during pregnancy and lactation.

What is the primary function of the parathyroid glands?

  1. Producing insulin

  2. Regulating blood pressure

  3. Controlling metabolism

  4. Producing parathyroid hormone


Correct Option: D
Explanation:

The parathyroid glands produce parathyroid hormone, which regulates calcium and phosphate levels in the body, maintaining bone health and preventing imbalances.

Which hormone is responsible for regulating the body's response to stress?

  1. Insulin

  2. Glucagon

  3. Cortisol

  4. Thyroxine


Correct Option: C
Explanation:

Cortisol is a hormone produced by the adrenal glands and plays a crucial role in regulating the body's response to stress, energy metabolism, and immune function.
