Which structure is primarily responsible for detecting rotational movement and contributing to the sense of balance?
Understand the Problem
The question is asking which part of the inner ear is responsible for detecting rotational movements and contributing to our sense of balance. Specifically, it wants us to identify the structure from the options provided (cochlea, saccule, utricle, semicircular canals) that performs this function.
Answer
Semicircular canals detect rotational movement and contribute to balance.
The semicircular canals, part of the vestibular system in the inner ear, are primarily responsible for detecting rotational movement and contributing to the sense of balance.
Answer for screen readers
The semicircular canals, part of the vestibular system in the inner ear, are primarily responsible for detecting rotational movement and contributing to the sense of balance.
More Information
The vestibular system includes both the semicircular canals (for rotational movement) and the otoliths (for linear acceleration).
Tips
It is a common mistake to think balance comes only from the ears. Vision and proprioception (body awareness) also play key roles.
