Which of the following structure of the human brain contains neurosecretory cells to produce hormones ?

Options

A. Adenohypophysis
B. Neurohypophysis
C. Hypothalamus
D. Sellaturcica

Answer

To solve the question "Which of the following structures of the human brain contains neurosecretory cells to produce hormones?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for the specific structure in the human brain that contains neurosecretory cells responsible for hormone production.

2. **Evaluate the Options**:
- **Option 1: Adenohypophysis (Anterior Pituitary)**:
- The adenohypophysis is known as the anterior pituitary. It plays a crucial role in regulating various physiological processes, including stress response, growth, reproduction, and lactation. However, it does not contain neurosecretory cells; instead, it produces hormones in response to signals from the hypothalamus.
- **Conclusion**: This option is incorrect.

- **Option 2: Neurohypophysis (Posterior Pituitary)**:
- The neurohypophysis is known as the posterior pituitary. It releases hormones such as vasopressin (antidiuretic hormone) and oxytocin, but it does not produce these hormones itself. Instead, it stores and releases hormones produced by the hypothalamus.
- **Conclusion**: This option is also incorrect.

- **Option 3: Hypothalamus**:
- The hypothalamus is a critical structure in the brain that contains neurosecretory cells. These cells produce hormones that are then transported to the pituitary gland for regulation of various bodily functions.
- **Conclusion**: This option is correct.

- **Option 4: Coelaturchia**:
- Coelaturchia is not a recognized structure in the context of human brain anatomy related to hormone production. It is likely a misnomer or an incorrect term in this context.
- **Conclusion**: This option is incorrect.

3. **Final Answer**: The correct answer is **Option 3: Hypothalamus**.
