Hair cell receptors
WebIn contrast to all nicotinic receptors, which serve excitatory neurotransmission, the activation of α9α10 produces hyperpolarization of hair cells. An evolutionary analysis has shown that the α10 subunit exhibits signatures of positive selection only along the mammalian lineage, strongly suggesting the acquisition of a unique function. WebBristle sensilla: Bristle neurons are mechanoreceptors that innervate hairs all along the body. Each neuron extends a dendritic process to innervate a single hair and projects its axon to the ventral nerve cord. These neurons are thought to mediate touch sensation by responding to physical deflections of the hair. [17]

They respond to vibrations of the basilar membrane via movement of the fine hairlike structures ( stereocilia) that protrude from them. In humans, there are 12,000 outer hair cells and 3,500 inner hair cells.
Hair follicle receptors called hair root plexuses sense when a hair changes position. Indeed, the most sensitive mechanoreceptors in humans are the hair cells in the cochlea of the inner ear (no relation to the follicular receptors – they are named for the hair-like mechanosensory stereocilia they possess); these … See more A mechanoreceptor, also called mechanoceptor, is a sensory receptor that responds to mechanical pressure or distortion.
