The receptors for soun d waves are present on

Options

A. Organs of Corti
B. Reissner's membrane
C. Semicircular canals
D. Sacculus.

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks where the receptors for sound waves are located.

2. **Review the Options**: The options provided are:
- A) Organ of Corti
- B) Resinous membrane
- C) Semicircular canal
- D) Saccule

3. **Understand the Function of Each Option**:
- **Organ of Corti**: This is known to be the primary structure in the cochlea that contains the sensory receptors for sound.
- **Resinous membrane**: This term is not commonly associated with sound perception.
- **Semicircular canal**: This structure is involved in balance and spatial orientation, not sound perception.
- **Saccule**: This is part of the vestibular system and is involved in balance, not directly in sound perception.

4. **Identify the Correct Answer**: The Organ of Corti is specifically designed to detect sound waves. It contains mechanoreceptors (hair cells) that respond to fluid motion caused by sound waves, converting mechanical energy into electrical signals that are sent to the brain.

5. **Conclusion**: The receptors for sound waves are present on the **Organ of Corti**.

**Final Answer**: The receptors for sound waves are present on the **Organ of Corti** (Option A).
