Why do vestibular receptors have a weak ability to adapt?

The vestibular apparatus is an organ that is responsible for the balance and orientation of a person in space. When a person moves his head, the receptors of the vestibular apparatus (located in the inner ear) are irritated and affect the muscles, so that the person can maintain the desired body position. Weak adaptation of the receptors of the vestibular apparatus to changes is a reliable guarantee of controlling the position of the body in space. With a high adaptation of receptors, a person would not be able to maintain the required position, since it would depend on changes in the environment.
