Which of the following is an accumulation and release centre of neurohormones

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Neurohormones**: Neurohormones are hormones that are produced by nerve cells (neurons) and released into the bloodstream. They play a crucial role in regulating various physiological processes in the body.

2. **Identifying the Source**: Neurohormones are primarily produced in the hypothalamus, which is a part of the brain that controls many bodily functions, including the release of hormones.

3. **Role of the Pituitary Gland**: The pituitary gland is divided into two parts: the anterior pituitary and the posterior pituitary. The posterior pituitary is specifically responsible for the storage and release of certain neurohormones.

4. **Focus on the Posterior Pituitary**: The posterior pituitary gland accumulates and releases neurohormones, particularly vasopressin (also known as antidiuretic hormone, ADH) and oxytocin. These hormones are synthesized in the hypothalamus and transported to the posterior pituitary for storage and release.

5. **Functions of Neurohormones**:
- **Vasopressin**: Helps regulate blood pressure and fluid balance in the body.
- **Oxytocin**: Plays a role in childbirth by stimulating uterine contractions and is also involved in various social bonding behaviors.

6. **Conclusion**: Based on the information, the correct answer to the question about the accumulation and release center of neurohormones is the **posterior pituitary gland**.
