Neurohypophysis secretes-

Options

A. Vasopressin and growth hormone
B. Oxytocin and estrogen
C. Vasopressin and oxytocin
D. Vasopressin and estrogen

Answer

### Step-by-Step Solution:

1. **Identify Neurohypophysis**: The neurohypophysis is also known as the posterior lobe of the pituitary gland. It plays a crucial role in the endocrine system.

2. **Understand its Function**: The primary function of the neurohypophysis is to secrete, release, and store hormones. It does not produce hormones itself but releases those produced by the hypothalamus.

3. **Identify the Hormones Secreted**: The neurohypophysis secretes two main hormones:
- **Vasopressin (also known as Antidiuretic Hormone, ADH)**: This hormone helps regulate water balance in the body by controlling the amount of water reabsorbed by the kidneys.
- **Oxytocin**: This hormone is involved in various functions, including stimulating uterine contractions during childbirth and promoting milk ejection during breastfeeding.

4. **Regulation of Secretion**: The secretion of these hormones is regulated by neurons originating from the hypothalamus. The hypothalamus sends signals to the neurohypophysis to release these hormones into the bloodstream.

5. **Conclusion**: Therefore, the neurohypophysis secretes vasopressin and oxytocin, which are critical for various physiological functions in the body.
