May 10, 2024 · Anatomy. Function. Associated Conditions. Tests. The cochlea is a fluid-filled, snail-like structure within a cavity in the inner ear. It plays a vital role in the function of hearing rather than simply being another component of the skeletal system. The cochlea contains hair cells that convert sound waves into electrical impulses that are ...
Oct 30, 2023 · 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.

Mar 4, 2024 · 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). These chambers are filled with fluid that moves in ...
The cochlear nerve, also known as the acoustic or auditory nerve, is the cranial nerve responsible for hearing. It travels from the cochlea in the inner ear to the brainstem as part of the eighth cranial nerve. Pathology of the cochlear nerve may result from inflammation, infection, injury, or a tumor (acoustic neuroma).
Aug 22, 2024 · Inner Ear. Your inner ear is the innermost part of your hearing system and home to your vestibular (balance) system. It contains the cochlea, which helps you hear, and the semicircular canals and otolith organs that help you balance. You can protect your inner ear by avoiding things, like loud noises, that can damage the sensitive structures ...
Jan 22, 2018 · Inner ear: The inner ear, also called the labyrinth, operates the body’s sense of balance and contains the hearing organ. A bony casing houses a complex system of membranous cells. The inner ear ...

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). The spiral canal of the cochlea is a section of the bony labyrinth of the inner ear that is approximately 30 mm long and makes 2 3⁄4 turns ...
