Out of the following hormones, how many are secreted from adenohypophysis?
[Prolactin, ADH , GH, LH, Aldosterone, MSH, Melatonin, PTH]

Options

A. One
B. Two
C. Three
D. Four

Answer

To solve the question of how many hormones are secreted from the adenohypophysis (anterior pituitary), we will analyze each hormone listed in the options provided.

**Step 1: Identify the hormones listed in the question.**
The hormones given are:
1. Prolactin
2. ADH (Antidiuretic Hormone)
3. GH (Growth Hormone)
4. LH (Luteinizing Hormone)
5. Aldosterone
6. MSH (Melanocyte Stimulating Hormone)
7. Melatonin
8. PTH (Parathyroid Hormone)

**Step 2: Determine which hormones are secreted from the adenohypophysis.**
- **Prolactin**: Secreted from the anterior pituitary. (Correct)
- **ADH**: Secreted from the posterior pituitary. (Incorrect)
- **GH (Growth Hormone)**: Secreted from the anterior pituitary. (Correct)
- **LH (Luteinizing Hormone)**: Secreted from the anterior pituitary. (Correct)
- **Aldosterone**: Secreted from the adrenal cortex. (Incorrect)
- **MSH (Melanocyte Stimulating Hormone)**: Secreted from the anterior pituitary. (Correct)
- **Melatonin**: Secreted from the pineal gland. (Incorrect)
- **PTH (Parathyroid Hormone)**: Secreted from the parathyroid glands. (Incorrect)

**Step 3: Count the hormones that are secreted from the adenohypophysis.**
From the analysis:
- Prolactin: Yes
- GH: Yes
- LH: Yes
- MSH: Yes

Total hormones secreted from the adenohypophysis = 4 (Prolactin, GH, LH, MSH)

**Final Answer: 4 hormones are secreted from the adenohypophysis.**
