membranous labyrinth inner ear 3D anatomy cochlear duct utricle saccule semicircular ducts

~/

Accurate 3D anatomical educational illustration of the human membranous labyrinth of the inner ear, isolated on a plain white background. Show a translucent bony labyrinth outline containing the blue membranous labyrinth: cochlear duct within a spiral cochlea, utricle, saccule, anterior posterior and lateral semicircular ducts with ampullae, ductus reuniens, utriculosaccular duct, endolymphatic duct and endolymphatic sac. Clearly label all named structures with clean leader lines. Medical textbook style, accurate spatial anatomy.
