  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Thyroxine


Correct Option: B
Explanation:

Insulin is the primary hormone involved in regulating blood sugar levels by promoting the uptake and utilization of glucose by cells.

The release of which hormone is stimulated by the hypothalamus and controls the activity of the adrenal glands?

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Thyroxine


Correct Option: A
Explanation:

Epinephrine, also known as adrenaline, is released in response to stress and prepares the body for the 'fight or flight' response.

Which hormone is produced by the thyroid gland and plays a crucial role in metabolism?

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Thyroxine


Correct Option: D
Explanation:

Thyroxine, also known as T4, is a thyroid hormone that regulates metabolism, growth, and development.

The hormone responsible for stimulating the production of milk in lactating women is:

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Prolactin


Correct Option: D
Explanation:

Prolactin, produced by the pituitary gland, promotes milk production during lactation.

Which hormone is involved in the regulation of calcium and phosphate metabolism?

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Parathyroid hormone


Correct Option: D
Explanation:

Parathyroid hormone, secreted by the parathyroid glands, regulates calcium and phosphate levels in the blood.

The hormone that stimulates the release of glucose from the liver into the bloodstream is:

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Thyroxine


Correct Option: C
Explanation:

Glucagon, produced by the pancreas, raises blood sugar levels by promoting the breakdown of glycogen in the liver.

Which hormone is responsible for regulating the menstrual cycle and preparing the uterus for pregnancy?

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Progesterone


Correct Option: D
Explanation:

Progesterone, produced by the ovaries, plays a crucial role in the menstrual cycle and pregnancy.

The hormone that controls the development of male secondary sexual characteristics is:

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Testosterone


Correct Option: D
Explanation:

Testosterone, produced by the testes, is responsible for the development of male secondary sexual characteristics.

Which hormone is produced by the pituitary gland and stimulates the growth of bones and muscles?

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Growth hormone


Correct Option: D
Explanation:

Growth hormone, also known as somatotropin, promotes growth and development in children and adolescents.

The hormone that regulates the body's response to stress is:

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Thyroxine


Correct Option: A
Explanation:

Epinephrine, also known as adrenaline, is released in response to stress and prepares the body for the 'fight or flight' response.

Which hormone is involved in the regulation of blood pressure and fluid balance?

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Aldosterone


Correct Option: D
Explanation:

Aldosterone, produced by the adrenal glands, regulates blood pressure and fluid balance by controlling sodium and potassium levels.

The hormone that stimulates the production of red blood cells is:

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Erythropoietin


Correct Option: D
Explanation:

Erythropoietin, produced by the kidneys, stimulates the production of red blood cells in response to low oxygen levels.

Which hormone is responsible for regulating sleep-wake cycles?

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Melatonin


Correct Option: D
Explanation:

Melatonin, produced by the pineal gland, regulates sleep-wake cycles and helps maintain the body's circadian rhythm.

The hormone that controls the release of hormones from the pituitary gland is:

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Thyrotropin-releasing hormone


Correct Option: D
Explanation:

Thyrotropin-releasing hormone, produced by the hypothalamus, stimulates the pituitary gland to release thyroid-stimulating hormone.

Which hormone is involved in the regulation of appetite and body weight?

  1. Epinephrine

  2. Insulin

  3. Glucagon

  4. Leptin


Correct Option: D
