검증된 단계별 안내1
Understand the anatomy of the semicircular canals: These are three looped structures located in the inner ear, oriented in three different planes, which help detect rotational movements.
Recognize the role of hair cells: Hair cells are sensory receptors located within the ampullae of the semicircular canals. They are responsible for detecting changes in head position.
Identify the type of movement detected: The semicircular canals are specifically designed to detect rotational movements of the head, such as turning or tilting.
Differentiate from other sensory functions: Light intensity is detected by photoreceptors in the eyes, linear acceleration is detected by the otolith organs (utricle and saccule), and sound waves are detected by hair cells in the cochlea.
Conclude that the semicircular canals, through the hair cells, are specialized for sensing rotational movements of the head, not light intensity, linear acceleration, or sound waves.
