All of these are true w r t organ of Corti except

Options

A. located on Reissner's membrane
B. pressing of steroreocillia against tectonical membrane generates nerve impulses
C. impulses are carried to brain by cochlear branch of auditory nerve
D. it does not have any role in balancing

Answer

To solve the question regarding the statements about the organ of Corti, we will analyze each option provided and determine which statement is incorrect.

### Step-by-Step Solution:

1. **Understanding the Organ of Corti**: The organ of Corti is a structure located within the cochlea of the inner ear and is responsible for converting sound vibrations into nerve impulses.

2. **Analyzing the Options**:
- **Option 1**: "Located on the basilar membrane."
- This statement is **incorrect**. The organ of Corti is indeed located on the basilar membrane, not the "reasoner membrane" (which seems to be a typographical error).

- **Option 2**: "Pressing of stereocilia against tectorial membrane generates nerve impulses."
- This statement is **correct**. The stereocilia of the hair cells in the organ of Corti bend against the tectorial membrane, leading to the generation of nerve impulses.

- **Option 3**: "Impulses are carried to the brain by the cochlear branch of the auditory nerve."
- This statement is **correct**. The auditory nerve (cochlear branch) transmits the nerve impulses generated by the organ of Corti to the brain.

- **Option 4**: "It does not have any role in balancing."
- This statement is **correct**. The organ of Corti is primarily involved in hearing and does not play a role in balance, which is managed by other structures in the inner ear.

3. **Conclusion**: Based on the analysis, the statement that is incorrect is **Option 1**, as it misstates the location of the organ of Corti.

### Final Answer:
The incorrect statement regarding the organ of Corti is: **"Located on the reasoner membrane."**
