Deiters' cells, also known as outer phalangeal cells or cells of Deiters (English: / ˈ d aɪ t ər z /), are a cell type found within the inner ear. They contain both microfilaments and microtubules which run from the basilar membrane to the reticular membrane of the inner ear.
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates , the inner ear is mainly responsible for sound detection and balance. [ 1 ] In mammals , it consists of the bony labyrinth , a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: [ 2 ]
The inner ear houses the apparatus necessary to change the vibrations transmitted from the outside world via the middle ear into signals passed along the vestibulocochlear nerve to the brain. The hollow channels of the inner ear are filled with liquid, and contain a sensory epithelium that is studded with hair cells. The microscopic "hairs" of ...
Facing the inner ear, the medial wall (or labyrinthic wall, labyrinthine wall) is vertical, and has the oval window and round window, the promontory, and the prominence of the facial canal. Facing the outer ear , the lateral wall (or membranous wall ), is formed mainly by the tympanic membrane , partly by the ring of bone into which this ...
Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals. As movements consist of rotations and translations, the vestibular system comprises two components: the semicircular canals, which indicate rotational movements; and the otoliths, which indicate linear accelerations.
The inner ear consists of the cochlea and several non-auditory structures. The cochlea has three fluid-filled sections (i.e. the scala media, scala tympani and scala vestibuli) , and supports a fluid wave driven by pressure across the basilar membrane separating two of the sections.
The utricle and saccule are the two otolith organs in the vertebrate inner ear.The word utricle comes from Latin uter 'leather bag'. The utricle and saccule are part of the balancing system (membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). [1]
The vestibule is the central part of the bony labyrinth in the inner ear, and is situated medial to the eardrum, behind the cochlea, and in front of the three semicircular canals. [1] The name comes from the Latin vestibulum, literally an entrance hall.
