D. Five

Answer

To determine the number of endocrine glands related to the brain, we will identify the major endocrine glands located within the brain. Here is a step-by-step solution:

### Step 1: Identify the Endocrine Glands
The primary endocrine glands associated with the brain include:
1. **Hypothalamus**
2. **Pituitary Gland**
3. **Pineal Gland**

### Step 2: Describe Each Gland
- **Hypothalamus**:
- Located in the basal part of the diencephalon.
- Acts as a crucial link between the nervous system and the endocrine system, regulating various body functions.

- **Pituitary Gland**:
- Situated in a bony cavity of the sphenoid bone known as the sella turcica.
- Connected to the hypothalamus via the infundibulum and is often referred to as the "master gland" due to its role in regulating other endocrine glands.

- **Pineal Gland**:
- Located on the dorsal side of the forebrain.
- Primarily responsible for the production of melatonin, which regulates sleep-wake cycles.

### Step 3: Count the Glands
From the above information, we can conclude that there are **three** major endocrine glands related to the brain: the hypothalamus, pituitary gland, and pineal gland.

### Final Answer
Thus, the number of endocrine glands related to the brain is **3**.
