Human anatomy, including structure and development and practical considerations . ^helicotreiiia SiHla vestibuli Scala tynipair ModiohiArea cochlearis Area vestibularis inferio Internal auditory canal Foramen sinsulare. Lamina spiralis ossea Canalis spiralis modioli Facial canalCrista falciformis . vestibularissuperior Cochlea and bottom of internal auditory canal exposed by vertical section ; parallel with zygoma; prepara-tion has been turned so that cochlea rests with its base downward and apex pointing upward. X 5. zontally outward, somewhat forward and downward, and reaches almost to the Eusta-chian tube. Its large lower turn bulges into the tympanic cavity and produces theconspicuous elevation of the promontory seen on the inner wall of the middle ear(Fig. 1269). The bony cochlea consists essentially of a tapering central column,the modiolus, around which the bony canal, about 30 mm. long, makes somethingmore than two and a half spiral turns, the basal, middle and apical. The conicalmodiolus has a broad concave base which forms part of the base of the cochlea (basiscochlea), and a small apex which extends nearly to the apex of the cochlea, orcupola (cupula). It is much thicker withi
