Above the cochlea is a complex system called the vestibular apparatus, which is located in the inner ear.
Three semicircular canals and the otolith make up the vestibular apparatus (macula is the sensory part of saccule and utricle).
Each semi-circular canal is at right angles to the others and lies in a different plane. 4 The perilymph of the bony canals suspends the membranous canals.
The base of the canals is swollen and is called an ampulla; it has a projecting ridge with hair cells called the crista ampullaris.
The macula is a projecting ridge found in the saccule and utricle.
The crista and macula are vestibular apparatus receptors that are responsible for maintaining body balance and posture.
