Select the specific receptors in inner ear responsible for the balance of body and posture.

The inner ear's vestibular system includes the semicircular canals, which have a swelling called the ampulla containing the crista ampullaris with hair cells. The utricle and saccule have projecting ridges called maculae, also with hair cells. These structures are the specific receptors responsible for detecting head movements, linear accelerations, and changes in head position, helping maintain balance and posture.
