  1. Growth hormone (GH)

  2. Prolactin (PRL)

  3. Adrenocorticotropic hormone (ACTH)

  4. Thyroid-stimulating hormone (TSH)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Adrenocorticotropic hormone (ACTH) is produced by the adenohypophysis and stimulates the production of cortisol by the adrenal glands, which is essential for stress response and energy metabolism.

Multiple choice

Which hormone is produced by the adenohypophysis and is responsible for stimulating the production of thyroid hormones by the thyroid gland?

  1. Growth hormone (GH)

  2. Prolactin (PRL)

  3. Adrenocorticotropic hormone (ACTH)

  4. Thyroid-stimulating hormone (TSH)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Thyroid-stimulating hormone (TSH), also known as thyrotropin, is produced by the adenohypophysis and stimulates the production of thyroid hormones by the thyroid gland, which are essential for metabolism and energy production.

Multiple choice

The neurohypophysis, also known as the posterior pituitary, is responsible for storing and releasing two hormones. Which of the following hormones is not stored in the neurohypophysis?

  1. Antidiuretic hormone (ADH)

  2. Oxytocin

  3. Growth hormone (GH)

  4. Prolactin (PRL)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Growth hormone (GH) is not stored in the neurohypophysis. It is produced and stored in the adenohypophysis.

Multiple choice

Antidiuretic hormone (ADH), also known as vasopressin, is produced by the hypothalamus and stored in the neurohypophysis. What is the primary function of ADH?

  1. Regulating blood pressure

  2. Stimulating milk production

  3. Promoting growth and development

  4. Conserving water in the body
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Antidiuretic hormone (ADH) is primarily responsible for conserving water in the body by reducing urine output and increasing water reabsorption in the kidneys.

Multiple choice

Which test measures the level of thyroid-stimulating hormone (TSH) in the blood?

  1. Thyroid Function Test (TFT)

  2. Free Thyroxine (FT4) Test

  3. Triiodothyronine (T3) Test

  4. Thyroid-Stimulating Hormone (TSH) Test
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The TSH test is primarily used to assess thyroid function by measuring the level of TSH, which is produced by the pituitary gland to regulate thyroid hormone production.
