Answer

To solve the question regarding the joint not associated with the upper limb bones of humans, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the joint that is not associated with the upper limb bones in humans. The upper limb includes the shoulder, arm, forearm, wrist, and hand.

2. **Identify the Joints in the Upper Limb**:
- **Shoulder Joint**: The shoulder joint is a ball-and-socket joint, which allows for a wide range of movement.
- **Elbow Joint**: The elbow is a hinge joint, allowing for flexion and extension.
- **Wrist Joint**: The wrist has several joints, including the radiocarpal joint, which is classified as a condyloid joint.
- **Finger Joints**: The joints in the fingers include hinge joints and condyloid joints.

3. **List the Types of Joints**:
- **Saddle Joint**: Found in the thumb (carpometacarpal joint).
- **Hinge Joint**: Present in the elbow and fingers.
- **Condyloid Joint**: Present in the wrist and fingers.
- **Synarthrosis**: This is a type of joint that is immovable and is not typically found in the upper limb.

4. **Determine the Answer**:
- Since the question specifically asks for a joint not associated with the upper limb, and we have identified that synarthrosis is an immovable joint not found in the upper limb, we conclude that synarthrosis is the correct answer.

### Final Answer:
The joint not associated with the upper limb bones of humans is **synarthrosis**.
