CHAPTER 14 Models of Hair Cell Mechanotransduction - MPI
... Hair cells are specialized receptor cells that transduce mechanical force (e.g., from sound waves, gravity, or vibrations) into an electrical signal. The receiving subcellular organelle, the hair bundle, exhibits a delicate and unique architecture (Fig. 1A). Rows of stereocilia, actin‐filled protrus ...

Auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
