Verified step by step guidance

Understand the role of the utricle in the vestibular system, which is part of the inner ear responsible for balance and spatial orientation.

Recognize that the utricle, along with the saccule, is one of the otolithic organs that detect linear accelerations and head position relative to gravity.

Identify that the utricle is specifically sensitive to linear accelerations in the horizontal plane, such as forward and backward movements or side-to-side tilts.

Differentiate between the utricle and the saccule, noting that the saccule is more sensitive to vertical accelerations, such as up and down movements.

Conclude that the utricle's sensitivity to horizontal plane movements helps maintain balance and spatial orientation during activities like walking or driving.
