The specific receptor responsible for the balance of the body and posture are

Options

A. Organ of corti
B. Crista and macula
C. Tectorial membrane
D. Basilar membrane

Answer

To answer the question regarding the specific receptor responsible for the balance of the body and posture, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Identify the Function of the Receptors**: We need to determine which receptors are involved in maintaining balance and posture in the body.

2. **Evaluate the Options**:
- **Option A: Organ of Corti**: This structure is primarily involved in hearing. It transduces auditory signals and is not responsible for balance or posture. Therefore, this option is incorrect.

- **Option B: Crista and Macula**: The crista is located in the ampulla of the semicircular canals, and the macula is found in the saccule and utricle of the vestibular apparatus. Both structures play a crucial role in detecting changes in head position and motion, which are essential for maintaining balance and posture. Thus, this option is correct.

- **Option C: Tectorial Membrane**: This membrane is associated with the Organ of Corti and is involved in converting sound vibrations into mechanical stimulation. It does not have a role in balance or posture. Therefore, this option is incorrect.

- **Option D: Basilar Membrane**: This membrane is also related to the auditory system and helps in the process of hearing. It does not contribute to balance or posture, making this option incorrect as well.

3. **Conclusion**: After evaluating all the options, it is clear that the correct answer is **Option B: Crista and Macula**, as they are specifically responsible for the balance of the body and posture.

### Final Answer:
The specific receptor responsible for the balance of the body and posture is **Crista and Macula**.
