Which of the following endocrine glands is the centre for formation of neurohormones ?

Options

A. Posterior pituitary lobe
B. Intermediate lobe of the pituitary
C. Hypothalamus
D. Anterior pituitary lobe

Explanation

To answer the question "Which of the following endocrine glands is the centre for formation of neurohormones?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Neurohormones**: Neurohormones are hormones released by neurosecretory cells, which are specialized neurons that secrete hormones into the bloodstream.

2. **Identifying the Endocrine Glands**: The question requires us to identify which endocrine gland is responsible for the formation of these neurohormones. The key glands to consider are the hypothalamus, pituitary gland (anterior and posterior lobes), and possibly others.

3. **Role of the Hypothalamus**: The hypothalamus is located in the forebrain, just below the thalamus. It is known as the master regulator of the endocrine system. The hypothalamus contains neurosecretory cells that produce neurohormones.

4. **Types of Neurohormones**: The neurohormones produced by the hypothalamus can be classified into two categories:
- **Releasing hormones**: These stimulate the anterior pituitary to release its hormones.
- **Inhibiting hormones**: These inhibit the release of hormones from the pituitary.

5. **Connection to the Pituitary Gland**: The neurohormones produced in the hypothalamus are transported to the pituitary gland. The posterior pituitary gland stores and releases two specific neurohormones: Antidiuretic Hormone (ADH) and Oxytocin. However, these hormones are not formed in the posterior pituitary; they are produced in the hypothalamus.

6. **Conclusion**: Based on the above points, the endocrine gland that is the center for the formation of neurohormones is the **hypothalamus**.

### Final Answer:
The correct answer to the question is the **hypothalamus**.
