The chief function of the utriculus is

Options

A. hearing
B. to help in body equilibrium
C. to perceive pressure
D. all of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Utriculus**: The utriculus, or utricle, is one of the two otolith organs located in the inner ear, specifically part of the vestibular system. It plays a crucial role in maintaining balance and spatial orientation.

2. **Location in the Ear**: The utricle is situated in the inner ear alongside the saccule. Together, they are responsible for detecting changes in head position and motion.

3. **Function of the Utriculus**: The primary function of the utriculus is to help maintain body equilibrium. It detects linear accelerations and the effects of gravity, which are essential for balance.

4. **Differentiating Functions**: While the utriculus is involved in balance, it does not primarily function to perceive pressure. The perception of pressure is typically associated with other sensory systems.

5. **Conclusion**: Therefore, the chief function of the utriculus is to help in body equilibrium.

**Final Answer**: The chief function of the utriculus is to help in body equilibrium.
