What is the other name of vasopressin ?

Options

A. ADH
B. ACTH
C. LH
D. FSH.

Answer

**Step-by-Step Solution:**

1. **Understanding Vasopressin**: Begin by identifying what vasopressin is. Vasopressin is a hormone that plays a crucial role in regulating the body's retention of water and is involved in various physiological processes.

2. **Identifying Its Other Name**: The other name for vasopressin is "Antidiuretic Hormone" (ADH). This name reflects its primary function of reducing urine production by promoting water reabsorption in the kidneys.

3. **Source of Vasopressin**: Vasopressin is secreted from the posterior lobe of the pituitary gland. This is important to note as it helps in understanding where this hormone originates.

4. **Function of Vasopressin**: The main function of vasopressin (ADH) is to increase the reabsorption of water in the kidneys, which decreases urine output. This is critical for maintaining the body’s fluid balance.

5. **Eliminating Other Options**: In the context of the question, it is important to differentiate vasopressin from other hormones. For instance:
- ACTH (Adrenocorticotropic Hormone) is secreted from the anterior lobe of the pituitary gland and is involved in stimulating the adrenal cortex.
- LH (Luteinizing Hormone) and FSH (Follicle Stimulating Hormone) are also secreted from the anterior pituitary and are involved in reproductive functions.

6. **Conclusion**: Based on the above points, the correct answer to the question "What is the other name of vasopressin?" is ADH (Antidiuretic Hormone).

**Final Answer**: The other name of vasopressin is Antidiuretic Hormone (ADH).
