Which of the following integrates Nervous and endocrine system

Options

A. Hypothalamus
B. Pineal gland
C. Adrenal gland
D. Thymus

Answer

To solve the question "Which of the following integrates the Nervous and endocrine system?", we will analyze each option provided and identify the correct answer step by step.

### Step 1: Understand the question
We need to determine which structure in the body serves as a link between the nervous system and the endocrine system.

### Step 2: Analyze the options
1. **Hypothalamus**: This is a small region in the brain that plays a crucial role in linking the nervous system to the endocrine system. It regulates various bodily functions and produces releasing and inhibiting hormones that control the pituitary gland.

2. **Pineal gland**: This gland is primarily responsible for the production of melatonin, which regulates sleep patterns but does not integrate the nervous and endocrine systems.

3. **Adrenal gland**: These glands produce hormones like adrenaline and cortisol in response to stress but do not serve as a direct link between the nervous and endocrine systems.

4. **Thymus**: This gland is involved in the immune response and the development of T-cells but does not integrate the nervous and endocrine systems.

### Step 3: Identify the correct answer
Based on the analysis, the **hypothalamus** is the structure that integrates the nervous and endocrine systems by regulating hormone release and inhibiting hormones.

### Conclusion
The correct answer is **Hypothalamus**.
