Which of the following given the structure of the human body can possess maximum type of synovial joints?

Options

A. Human skull bones
B. Human hand
C. Human Cervical vertebrae
D. Human knee

Answer

To solve the question regarding which structure of the human body can possess the maximum types of synovial joints, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Synovial Joints**:
- Synovial joints are characterized by the presence of synovial fluid, which allows for free movement between the articulating bones. They are the most common type of joint in the human body and include various subtypes such as hinge joints, ball-and-socket joints, pivot joints, saddle joints, and gliding joints.

2. **Evaluating the Options**:
- **Option A: Human Skull Bones**:
- The joints in the human skull are primarily fibrous joints (sutures) that do not allow movement. Therefore, this option does not contain synovial joints.

- **Option B: Human Hand**:
- The human hand consists of 27 bones including carpals, metacarpals, and phalanges. It contains multiple types of synovial joints such as hinge joints (e.g., finger joints), saddle joints (e.g., thumb joint), and gliding joints (e.g., between carpal bones). This option has a variety of synovial joints.

- **Option C: Human Cervical Vertebra**:
- The cervical vertebrae are connected by cartilaginous joints (intervertebral discs) and synovial joints (facet joints), but they do not have as many types of synovial joints as the human hand.

- **Option D: Human Knee**:
- The human knee is primarily a hinge joint, allowing movement in one direction. While it is a significant synovial joint, it does not possess the variety of synovial joint types found in the human hand.

3. **Conclusion**:
- After evaluating all the options, the human hand possesses the maximum types of synovial joints due to its complex structure and variety of movements allowed by different joint types.

### Final Answer:
- The correct answer is **Human Hand** (Option B).
