the Minotaur.
The labyrinth is a system of fluid passages in the inner ear,
comprising the semicircular canals and the vestibule, which provides the sense of balance. It is named by analogy with the mythical maze that
imprisoned the Minotaur, because of its appearance.
Three structures of the labyrinth, the semicircular canals,
let us know when we are in a rotary (circular) motion. The semicircular canals, the superior, posterior, and horizontal, are
filled with fluid. Motion of the fluid tells us if we are moving. The semicircular canals and the visual and skeletal systems
have specific functions that determine an individual's orientation. The vestibule is the region of the inner ear where the
semicircular canals converge, close to the cochlea (the hearing organ). The vestibular system works with the visual system to
keep objects in focus when the head is moving. Joint and muscle receptors also are important in maintaining balance. The brain
receives, interprets, and processes the information from these systems that control our balance.
Interference with or infection of the Labyrinth can result in a syndrome of ailments called Labyrinthitis. The
symptoms of Labrynthitis include temporary nausea, disorientation, vertigo, and dizziness. Labyrinthitis can be caused by viral
infections, bacterial infections, or physical blockage of the inner ear.
