With reference to the pituitary, which of the following statements is correct?

Options

A. Neurohypophysis synthesis vasopressin and oxytocin.
B. Adenohypophysis stores TSH and STH secreted by neurohypophysis.
C. Neurohypophysis collects and stores vasopressin and oxytocin.
D. Adenohypophysis secretes vasopressin and oxytocin.

Explanation

To determine the correct statement regarding the pituitary gland, we need to analyze the roles of its two parts: the adenohypophysis and the neurohypophysis.

### Step-by-Step Solution:

1. **Understand the Structure of the Pituitary Gland**:
- The pituitary gland is divided into two main parts: the adenohypophysis (anterior pituitary) and the neurohypophysis (posterior pituitary).

2. **Identify the Functions of Each Part**:
- **Adenohypophysis**: This part is responsible for the synthesis and secretion of several hormones, including:
- Follicle Stimulating Hormone (FSH)
- Luteinizing Hormone (LH)
- Thyroid Stimulating Hormone (TSH)
- Growth Hormone (GH or STH)
- Melanocyte Stimulating Hormone (MSH)
- **Neurohypophysis**: This part does not synthesize hormones but stores and releases hormones produced by the hypothalamus, specifically:
- Vasopressin (also known as Antidiuretic Hormone, ADH)
- Oxytocin

3. **Evaluate Each Statement**:
- **Option A**: Neurohypophysis synthesizes vasopressin and oxytocin.
- This is incorrect because these hormones are synthesized in the hypothalamus, not the neurohypophysis.
- **Option B**: Adenohypophysis stores TSH and STH secreted by neurohypophysis.
- This is incorrect because TSH and STH are produced and secreted by the adenohypophysis itself, not stored from the neurohypophysis.
- **Option C**: Neurohypophysis collects and stores vasopressin and oxytocin.
- This is correct as the neurohypophysis stores hormones produced by the hypothalamus.
- **Option D**: Adenohypophysis secretes vasopressin and oxytocin.
- This is incorrect because these hormones are secreted by the neurohypophysis.

4. **Conclusion**:
- The correct statement is **Option C**: Neurohypophysis collects and stores vasopressin and oxytocin.

### Final Answer:
**Option C**: Neurohypophysis collects and stores vasopressin and oxytocin.
