Updated April 11, 2017. The auditory ossicles are a chain of small bones in the middle ear that transmit sound from the outer ear to the inner ear as a mechanical vibration. The names of these three bones are taken from Latin. The malleus is also known as the hammer, the incus is also called the anvil, and the stapes is known as the stirrup..
The auditory nerve carries impulses from the cochlea to a relay station in the mid-brain, the cochlear nucleus. These nerve impulses are then carried on to other brain pathways that end in the auditory cortex (hearing part) of the brain.Also housed within the inner ear are the semicircular canals, the utricle, and the saccule. These structures help control oneâs sense of steadiness or balance.he inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals in the inner ear are part of our balance system. The cochlea is a bony structure shaped like a snail and filled with two fluids (endolymph and perilymph).
