The hormones of neuro hypophysis are formed in :-

Options

A. pars nervesa
B. Pars distalis
C. Supraoptic and paraventricular center
D. Hypothalamus

Answer

**Step-by-Step Solution:**

1. **Identify the Structure in Question**: The question asks about the hormones of the neurohypophysis, which is also known as the posterior pituitary gland.

2. **Understand the Function of Neurohypophysis**: The neurohypophysis is responsible for storing and releasing two main hormones: vasopressin (also known as antidiuretic hormone, ADH) and oxytocin.

3. **Locate the Source of Hormones**: While the neurohypophysis stores and releases these hormones, they are not produced there. Instead, they are synthesized in the hypothalamus.

4. **Identify Specific Areas in the Hypothalamus**: The hormones are specifically formed in two regions of the hypothalamus: the supraoptic nucleus and the paraventricular nucleus.

5. **Conclusion**: Therefore, the hormones of the neurohypophysis (vasopressin and oxytocin) are formed in the supraoptic and paraventricular centers of the hypothalamus.

**Final Answer**: The hormones of the neurohypophysis are formed in the supraoptic and paraventricular centers of the hypothalamus.
