labyrinth) arise. The common embryologic origin and structural
similarities of mature neuromasts and labyrinthine cell groups
have led to the designation of all of these organs as the
acoustico-lateralis system. The nerves to all the sense organs
of the system arise from a common neural centre (called the
acoustic tubercle in the wall of the brain’s medulla oblongata).
Among such... As receptors belonging to the acousticolateralis
system, the otolith organs of vertebrates have hair cells of the
same type that is found in lateral-line neuromasts. Under the
electron microscope, the sensory hair cells show a pattern of
polarization throughout the macula, indicating the directions in
which the shearing otolith should have an activating or an
inhibiting influence. Results of... vertebrate nervous system
