Verified step by step guidance

Understand the anatomy of the cochlea, which is part of the inner ear. The cochlea contains the spiral organ (also known as the organ of Corti), which is responsible for converting sound vibrations into neural signals.

Identify the key structures involved in the process of hearing within the cochlea: the oval window, round window, basilar membrane, and tectorial membrane.

Recognize that sound waves enter the cochlea through the oval window, causing fluid within the cochlea to move. This movement creates waves along the basilar membrane.

Learn that the basilar membrane supports the hair cells of the spiral organ. As the basilar membrane vibrates, it causes the hair cells to move against the tectorial membrane, leading to the stimulation of these hair cells.

Conclude that the vibration of the basilar membrane is the direct cause of hair cell stimulation in the spiral organ, as it is the movement of this membrane that leads to the bending of hair cells and the generation of neural signals.
