To describe:
The structures that are used to detect gravity and the orientation and movement of the head.
Introduction:
Apart from detecting sound, the inner ears of humans can also detect gravity and the orientation of the head, with the help of vestibular apparatus, present in the skull bones. Vestibular apparatus consists of a small chamber at its entrance called vestibule, and semicircular canals.
To determine:
How a single type of receptor, the hair cell, can respond to sound, gravity, or movement.
Introduction:
The movement of hair present on the floor of the cochlea, known as the basilar membrane, is responsible for detecting sound waves. The parts of the inner ears constituting the vestibular apparatus also contain hair cells, which are mechanoreceptor. Only these hair cells make it possible for the vestibular apparatus to detect head movement and gravity.
