Which of the following statements is NOT correct?

Options

A. Tendons are tissues with great strength and flexibility
B. Bones are connected to each other by tendons
C. Cartilage smoothens bone surface at joints
D. Tendons connect muscles to bones

Explanation

To solve the question "Which of the following statements is NOT correct?", we will analyze each statement provided in the options.

### Step-by-Step Solution:

1. **Understand the Function of Tendons**:
- Tendons are connective tissues that connect muscles to bones. They are known for their strength and some flexibility, allowing for movement when muscles contract.

**Hint**: Recall the role of tendons in the musculoskeletal system.

2. **Evaluate the First Statement**:
- "Tendons are tissue with great strength and flexibility."
- This statement is correct. Tendons do possess great strength and some degree of flexibility.

**Hint**: Think about the properties of tendons and their role in movement.

3. **Evaluate the Second Statement**:
- "Bones are connected to each other by tendons."
- This statement is incorrect. Bones are connected to each other by ligaments, not tendons. Tendons connect muscles to bones.

**Hint**: Remember the difference between ligaments and tendons.

4. **Evaluate the Third Statement**:
- "Cartilage smoothens bone surfaces at joints."
- This statement is correct. Cartilage acts as a cushion and reduces friction at the joints, allowing for smooth movement.

**Hint**: Consider the role of cartilage in joint function.

5. **Evaluate the Fourth Statement**:
- "Tendons connect muscles to bones."
- This statement is correct. As previously mentioned, tendons are responsible for connecting muscles to bones.

**Hint**: Revisit the definition of tendons and their connections.

6. **Conclusion**:
- After evaluating all statements, the statement that is NOT correct is: "Bones are connected to each other by tendons."

### Final Answer:
The statement that is NOT correct is: "Bones are connected to each other by tendons."
