Vestibular apparatus with utricle and saccule

A more detailed anatomical depiction of the inner ear vestibular apparatus including three semicircular canals arranged in different planes and connected to a central vestibule, with the utricle and saccule shown as small bulbous or sac-like chambers. Fine connecting ducts are visible, and the organ appears as pale beige membranous or bony tubes and sacs with translucent blue or blue-green internal fluid. The layout is compact and precise, emphasizing the distinct utricle-saccule swellings and otolith chambers within the vestibular region.
