The Organ of Corti is situated on the :

Options

A. Basilar membrane in tympanic canal
B. Reissner's membrane in vestibular canal
C. Besilar membrane in the median canal
D. Reissner's membrane in tympanic canal

Answer

**Step-by-Step Solution:**

1. **Understanding the Organ of Corti**: The Organ of Corti is a crucial structure in the cochlea of the inner ear that acts as the receptor organ for hearing. It is responsible for converting sound vibrations into neural signals.

2. **Analyzing the Options**:
- **Option 1**: Vascular membrane in tympanic canal. This option is incorrect because the tympanic canal does not contain the Organ of Corti.
- **Option 2**: Regional membrane in vestibular canal. This option is also incorrect as the regional membrane is not where the Organ of Corti is located.
- **Option 3**: Vascular membrane in the median canal. This is the correct option. The Organ of Corti is situated on the basilar membrane, which is located in the cochlea's median canal.
- **Option 4**: Regional membrane in the tympanic canal. This option is incorrect because the regional membrane is found in the vestibular canal, not the tympanic canal.

3. **Conclusion**: Based on the analysis, the correct answer is that the Organ of Corti is situated on the vascular membrane in the median canal.

**Final Answer**: The Organ of Corti is situated on the vascular membrane in the median canal.
