Hair Cell – A Biological Mechanoreceptor

The biological haircell is a neuron (note: it is not the hair that grows on our heads) that can receive mechanical input (called a mechanoreceptor).  A haircell consists of a hair (cilium) attached to a neuron.  The haircell is a modular building block responsible for hearing, flow sensing and vibration sensing  in many animal species.
