Identify the incorrect combination

Options

A. Incus-modified quadrate
B. Stapes-modified hyoid
C. Malleus-modified articular
D. Patella-ossified tendon

Answer

To identify the incorrect combination from the given options, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Analyze the First Option: Incus is the modified quadrate.**
- The incus is indeed one of the three auditory ossicles in mammals.
- It is derived from the quadrate bone of reptiles.
- **Conclusion:** This option is correct.

2. **Analyze the Second Option: Tapis is the modified hyoid.**
- The term "tapis" refers to a structure that is derived from the hyoid region.
- The hyomandibular bone is present in this region and is involved in the evolution of the tapis in tetrapods.
- **Conclusion:** This option is also correct.

3. **Analyze the Third Option: Malleus is the modified articulate.**
- The malleus is indeed formed from the modification of the articular bone.
- It evolved from the articular bone found in lower vertebrates.
- **Conclusion:** This option is correct.

4. **Analyze the Fourth Option: Patella is the ossified tendon.**
- The patella (kneecap) is considered to be a sesamoid bone that develops within a tendon.
- However, the statement mentions that this ossification is seen in rare conditions, such as after an injury (sleeve fracture).
- This suggests that the modification is not a natural occurrence but rather a pathological condition.
- **Conclusion:** This option is incorrect.

### Final Conclusion:
The incorrect combination is the fourth option: "Patella is the ossified tendon."
