Answer

To solve the question of identifying the INCORRECT statement related to the nervous system, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding the Statements**: We need to evaluate each statement provided about the nervous system to determine which one is incorrect.

2. **Statement Analysis**:
- **Statement 1**: "Organ of the eye, it is basically a part of ear, it's located on the tectoral membrane."
- **Analysis**: The Organ of Corti is indeed a part of the ear, but it is located on the basilar membrane, not the tectorial membrane. Therefore, this statement is incorrect.

- **Statement 2**: "The membrane in a semicircular canal of internal ear are suspended parallel from the bony canal."
- **Analysis**: This statement is correct. The membranous structures within the semicircular canals are indeed suspended within the bony labyrinth.

- **Statement 3**: "Along with the hypothalamus, it is a gland pituitary gland. The limbic system is involved in the regulation of sexual behavior."
- **Analysis**: This statement is also correct. The limbic system plays a significant role in regulating emotions and behaviors, including sexual behavior.

3. **Conclusion**: After analyzing all statements, we find that Statement 1 is incorrect. Therefore, the answer to the question is that the INCORRECT statement is Statement 1.

### Final Answer:
The INCORRECT statement is: "Organ of the eye, it is basically a part of ear, it's located on the tectoral membrane."
