Neurohypophysis secretes the

Options

A. Vasopressin and ACTH
B. ADH and Pitocin
C. Pitressin and ACTH
D. Oxytocin and LTH

Answer

To solve the question "Neurohypophysis secretes the", we will analyze the options provided and the functions of the neurohypophysis.

### Step-by-Step Solution:

1. **Identify Neurohypophysis**:
- The neurohypophysis is the posterior part of the pituitary gland, located below the hypothalamus. It is responsible for the secretion of certain hormones.

2. **Understand the Hormones Secreted by Neurohypophysis**:
- The primary hormones secreted by the neurohypophysis are:
- **Vasopressin (Antidiuretic Hormone, ADH)**: This hormone regulates water balance in the body by controlling the amount of water the kidneys reabsorb.
- **Oxytocin**: This hormone plays a crucial role during childbirth and lactation, stimulating uterine contractions and milk ejection.

3. **Analyze the Options**:
- **Option 1**: Vasopressin and ACTH
- Vasopressin is correct, but ACTH (Adrenocorticotropic Hormone) is secreted by the anterior pituitary, not the neurohypophysis. This option is incorrect.
- **Option 2**: ADH and Pitocin
- ADH is another name for Vasopressin, and Pitocin is a synthetic form of Oxytocin. Both are secreted by the neurohypophysis. This option is correct.
- **Option 3**: Pitrecin and ACTH
- Pitrecin is another name for Vasopressin, but ACTH is not secreted by the neurohypophysis. This option is incorrect.
- **Option 4**: Oxytocin and LTH
- Oxytocin is correct, but LTH (Luteotropic Hormone) is secreted by the anterior pituitary. This option is incorrect.

4. **Conclusion**:
- The correct answer is **Option 2: ADH and Pitocin**, as both hormones are secreted by the neurohypophysis.

### Final Answer:
Neurohypophysis secretes **ADH and Pitocin**.
