WebStatocysts contain inward-facing hair cells (brown) that detect movements of statoliths (purple), dense particles that move in response to gravity. The hair cells are synapsed … WebIn the vestibular system, the sensory epithelium organizes as a repeating mosaic which consists of supporting cells and type I and type II HCs that differ in morphology and physiology ( Warchol et al., 2024 ). However, the cochlea, a structure unique to mammals, has a more delicate sensory epithelium, also known as the organ of Corti.
