13. The inner air which is important in hearing and balance consists of Bony labyrinth which is made of temporal bone. Inside it two main structures are present. The cochlea- for hearing. The vestibular system-for Balance and equilibrium.
The fluid present in inner air is perilymph, based on the fluid moment the semicircular canal of vestibule detects equilibrium and balance of body
Both the vestibular system and cochlea are connected to brain via vestibulo cochlear nerve.
The semicircular canal are part of vestibule inside which the perilymph fluid present. This fluid motion detect balance. There are 3 canals present. Horizonal superior and posterior.
