The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Papillary Muscles**: Papillary muscles are specialized muscles located in the heart. They play a crucial role in the functioning of the heart valves. 2. **Function of Papillary Muscles**: Their primary function is to prevent the backflow of blood during the contraction of the heart (systole). They achieve this by anchoring the heart valves (specifically the atrioventricular valves) through structures called chordae tendineae. 3. **Identifying the Location**: Papillary muscles are specifically found in the ventricles of the heart. They are attached to the walls of the ventricles and connect to the heart valves. 4. **Evaluating the Options**: The question provides several options: - Ventricle - Heart of rabbit - Dermis of mammalian skin - Orbit of vertebrate eyes - Parallax of vertebrate stomach Among these options, "ventricle" is the most accurate answer since papillary muscles are located in the ventricles of the heart. 5. **Conclusion**: Therefore, the correct answer to the question "Papillary muscles are located in" is the "ventricle". **Final Answer**: Ventricle ---
