What contains receptor cells for hearing?
The cochlea is a fluid-filled, snail-shaped structure that contains the sensory receptor cells (hair cells) of the auditory system (Figure 1).
What does the basilar membrane do?
the basilar membrane is found in the cochlea; it forms the base of the organ of Corti, which contains sensory receptors for hearing. Movement of the basilar membrane in response to sound waves causes the depolarization of hair cells in the organ of Corti.
Which structure in this figure contains the sense organ for hearing?
The inner ear consists of two functional units: the vestibular apparatus, consisting of the vestibule and semicircular canals, which contains the sensory organs of postural equilibrium; and the snail-shell-like cochlea, which contains the sensory organ of hearing.
How does hearing work basilar membrane?
In human hearing, sound waves enter the outer ear and travel through the external auditory canal. The motion of the stapes against the oval window sets up waves in the fluids of the cochlea, causing the basilar membrane to vibrate. …
What is the function of scala media?
one of the three canals found in the cochlea; the scala media contains the Organ of Corti, which is the receptor organ for hearing.
Which structures in the ears contain sensory receptors for hearing Select all that apply?
Sensory receptors of hearing are hair cells, present on basilar membrane of cochlea. Sensory organ present on basilar membrane for hearing is formed by hair cells and the tissue is called Organ of Corti. Cochlea is a coiled structure. It is a bony tube on the outside, and a membranar tube is there on the inside.
What does basilar membrane look like?
The basilar membrane is a resonant structure varying systematically in width and stiffness. It is wider (0.42–0.65 mm) and more flaccid at the cochlear apex than at the base (0.08–0.16 mm). When a sound wave is transmitted to the fluid of the inner ear, the basilar membrane is set in motion.
What fluid is in scala media?
Scala media contains endolymph, a specialized fluid with a low concentration of Na+ and a high concentration of K+ (about 160 mM). The endolymph is also unusual because it has a positive electrical potential (about 90 mV), observable even in the absence of sound.
What scala media contains?
What part of the ear contains receptors for the vestibular branch of the auditory nerve?
There are five vestibular receptor organs in the inner ear: the utricle, the saccule, and three semicircular canals.
