Final answer:
The inner and outer hair cells of the organ of Corti have stereocilia embedded in the tectorial membrane. The inner hair cells are the primary auditory receptors.
Step-by-step explanation:
The inner and outer hair cells of the organ of Corti have stereocilia that are embedded in the tectorial membrane. The organ of Corti is responsible for transducing sound waves into electrical signals that can be interpreted by the brain. The inner hair cells are the primary auditory receptors, while the outer hair cells fine-tune incoming sound waves.
