hårcellen
Hårcellen, also known as the hair cell, is a specialized sensory receptor cell found in the auditory and vestibular systems of vertebrates. These cells play a critical role in converting mechanical stimuli—such as sound waves and head movements—into electrical signals that the nervous system can interpret.
Hair cells are named for their distinctive bundle of stereocilia, which resemble tiny hairs protruding from
The structure of hair cells includes a basal body, a cell body, and an apical tuft of
Hair cells are non-dividing and cannot regenerate in humans, making them particularly vulnerable to damage from
Their sensitivity and specificity make hair cells essential for auditory perception and equilibrium, highlighting their importance
