Solution
The correct option is C Sensory crista of ampulla
Ampulla is the enlargement of one end of semi-circular canal. It is the swollen base of semi-circular canals which are three semi-circular and interconnected tubes present in inner ear. These are a part of bony labyrinth. They contain a fluid called endolymph. Ampulla contains a projecting ridge called crista ampullaris. It contains hair cells which are sensory receptors present in organ of Corti and have cytoplasmic projections on the apical end called stereocilia. Crista contains specific receptors that sense movements in body and maintain dynamic equilibrium.So, the correct answer is 'Sensory crista of ampulla'.
