In FMA, this is systemically part of the bony labyrinth. Note this is an anatomical space in ZFA. The MA treatment has advantages for representing the neuroepithelium, which should not be part of bone.

(See Anatomical Atlas entry for semicircular canals by T. Whitfield.)[TAO] EV:0100365 TAO:0000431 In gnathostomes, each membranous labyrinth has three semicircular ducts that connect with a chamber known as the utriculus. These ducts are sometimes called canals, but technically the term semicircular canal applies to the spaces in the osseus labyrinth in which the semicircular ducts lie.[uncertain][VHOG] internal ear membranous labyrinth ear vesicle ectoderm-derived structure structure with developmental contribution from neural crest
