The cochlea (pl.: cochleae) is a spiraled, hollow, conical chamber of bone, in which waves propagate from the base (near the middle ear and the oval window) to the apex (the top or center of the spiral).

2025年2月12日 · The cochlea is a spiral tube that is coiled two and one-half turns around a hollow central pillar, the modiolus. It forms a cone approximately 9 mm (0.35 inch) in diameter at its base and 5 mm in height. When stretched out, the spiral tube is approximately 30 mm in length.

la cellule ciliée, à l’origine du message nerveux, et une fibre (bleue) du nerf auditif, qui le transmet l’information au cerveau. The cochlea is made up of three canals wrapped around a bony axis, the modiolus. These canals are: the scala tympani (3), the scala vestibuli (2) and the scala media (or cochlear duct) (1).

2023年10月30日 · The cochlea is a component of the labyrinth of the internal ear that is responsible for hearing. It is a hollow, spirally coiled chamber inside the temporal bone that makes 2.75 turns around its axis, which is called the modiolus. The cavity of the cochlea (cochlear canal) houses a triangular membranous duct, called the cochlear duct.

Intraspecific variation, primarily in the shape and orientation of the semicircular canals, may provide additional clues to help us better understand form and function of the inner ear. Keywords: cochlea, inner ear, semicircular canals, vestibule. The otic (ear) region is part of the special sensory division of the nervous system of vertebrates.

2025年1月20日 · The cochlea is a spiral-shaped, conical structure resembling a snail shell, typically making 2.5 turns around its central axis, known as the modiolus. It is divided longitudinally into three parallel chambers or scalae: the scala vestibuli, scala tympani, and scala media (cochlear duct).

a spiral tube shaped like a snail shell, forming part of the inner ear; it is the essential organ of hearing. adj., adj coch´lear. The cochlea is filled with fluid and is connected with the middle ear by two membrane-covered openings, the oval window (fenestra vestibuli) and the round window (fenestra cochleae).

The cochlea (Latin: cochlea) is a bony canal within the internal ear that forms a spiral shape, making 2.5 turns around its axis. In Greek, cochlea means snail, which suites this structure that resembles a snail.

2024年7月29日 · The cochlea is a shell-shaped spiral that turns between two-and-a-half and two-and-three-quarters times around the modiolus (a central column of porous bone). The spiral of the cochlea is separated by the osseous spiral lamina and consists of the scala tympani (lower portion), scala media and scala vestibuli (upper portion).

2017年9月1日 · In early literature about the mammalian inner ear, the hearing part, which looked remarkably like the shell of a land snail (Helix pomatia), was first called the cochlea by Fallopio in 1561 (Gitter 1990). The name “cochlea” is derived from the Latin for snail shell, which in turn is from the Greek κοχλίας (snail or screw).
