Options

A. pancreas
B. adrenal
C. liver
D. salivary glands

Explanation

To determine which gland is not associated with the alimentary canal, we can analyze the given options: pancreas, adrenal gland, liver, and salivary gland.

### Step-by-Step Solution:

1. **Identify the Glands**: Look at the four options provided:
- Pancreas
- Adrenal gland
- Liver
- Salivary gland

2. **Understand the Function of Each Gland**:
- **Pancreas**: Located posterior to the stomach, it secretes alkaline pancreatic juice essential for the digestion of starch, proteins, fats, and nucleic acids. It also produces hormones like insulin and glucagon that regulate glucose metabolism.
- **Adrenal Gland**: Found on top of each kidney, this gland functions as an endocrine gland and is involved in regulating body growth and development. It does not have a direct role in the digestive process.
- **Liver**: The largest gland in the body, located in the upper right abdomen, it produces bile which is crucial for the digestion of fats in the small intestine.
- **Salivary Gland**: Located outside the buccal cavity, these glands secrete saliva containing the enzyme salivary amylase, which begins the digestion of starch in the mouth.

3. **Determine Association with the Alimentary Canal**:
- The pancreas, liver, and salivary glands are all associated with the alimentary canal as they play roles in digestion.
- The adrenal gland, however, is not associated with the alimentary canal.

4. **Conclusion**: Based on the analysis, the gland that is not associated with the alimentary canal is the **adrenal gland**.

### Final Answer:
The gland not associated with the alimentary canal is the **adrenal gland**.
