SEMICIRCULAR CANALS ANATOMY

Three bony canals, which are shaped in a semi circle, can be found posterior to the vestibule. These canals are angled at almost right angles to their neighboring canal. Within these semicircular canals there additional, smaller canals which create the membranous labyrinth.

Each of the three main ducts is equipped with membranous ampulla at on end and is firmly attached to the utricle at the other end.

These ducts host receptors which discern angular acceleration and deceleration as it applies to the head and sensory adaptations which discern circular movements of the head.
