Now, let's look at the third component of the labyrinth – the semicircular component. This part of the labyrinth is composed of three semicircular bony structures that project from the vestibule in three different directions. Each of these three bony canals contains perilymph and encloses a membranous semicircular duct filled with endolymph.
Overview: Osseous labyrinth. The osseous labyrinth is a series of interconnected tubes and cavernous spaces in the petrous portion of the temporal bone. The osseous labyrinth is lined with periosteum and filled with a fluid, perilymph. This drawing demonstrates the shape the perilymph would assume when confined in the osseous labyrinth. 2 of 4.
