The Coton de Tulear Club of America chose to remain true to their breed, even though they were the oldest breed club. The Jack Russell Terrier also decided not to follow their counter-parts, the Parson Russell Terrier and Russell Terrier, to AKC acceptance.
The vestibulocochlear nerve (auditory vestibular nerve) , known as the eighth cranial nerve, transmits sound and equilibrium (balance) information from the inner ear to the brain.1  1 Structure.he vestibulocochlear nerve consists mostly of bipolar neurons and splits into two large divisions: the cochlear nerve and the vestibular nerve.
The air space of the middle ear connects to the back of the nose by the Eustachian tube. The inner ear is made up of two components. The cochlea is involved with hearing. The vestibular system helps with balance. The cochlea is a snail-shaped chamber filled with fluid. It is lined with special sensory cells called hair cells. These cells transform sound waves into electrical signals.
