What is the spiral organ of Corti?
The organ of Corti, also known as the spiral organ, is the receptor organ for hearing, located in the cochlea (housed inside the scala media). It is a strip of sensory epithelium made of hair cells which act as the sensory receptors of the inner ear.
How does the spiral organ of Corti work?
The Organ of Corti is an organ of the inner ear located within the cochlea which contributes to audition. The Organ of Corti includes three rows of outer hair cells and one row of inner hair cells. Vibrations caused by sound waves bend the stereocilia on these hair cells via an electromechanical force.
What is the function of the organ of Corti?
The organ of Corti is a specialized sensory epithelium that allows for the transduction of sound vibrations into neural signals. The organ of Corti itself is located on the basilar membrane.
What are 4 components of the organ of Corti?
( A ) The organ of Corti rests on the basilar membrane, and is composed of the sensory receptor cells (OHCs and IHCs), supporting cells ( yellow ), and the tectorial membrane (TM).
Where is the spiral organ of Corti located quizlet?
Organ of Corti (Inner Ear)
What is the function of the spiral organ quizlet?
What is the function of the spiral organ’s outer hair cells? Increase responsiveness of the inner hair cells by amplifying the motion of the basilar membrane.
What is the function of the organ of Corti quizlet?
Contains tiny hairs which acts as hearing receptors, converts sound vibrations into nerve impulses. You just studied 2 terms!
Where is the spiral organ located quizlet?
The inferior compartment of the cochlea within the membranous labyrinth of the inner ear, containing perilymph; it extends from the apex of the cochlea and the helicotrema which is the opening from the scala vestibuli to a membrane-covered opening in the wall of the inner ear called the round window.
How does the organ of Corti function to produce nerve impulses?
The organ of Corti contains sensory cells with hairlike projections, called hair cells, that are deformed by the progress of the wave. The hair cells trigger nerve impulses that travel along the cochlear nerve, a branch of the auditory nerve, to the brain, where they are interpreted as sound.
Which chamber contains the organ of Corti?
It is divided into three fluid-filled chambers, called scalae, that spiral around a bony core. The scala media, or cochlear duct, contains the organ of Corti, which perceives sound. The organ of Corti consists of supporting cells and many thousands of sensory hair cells.
What are the functions of the spiral organ?
The organ of Corti, or spiral organ, is the receptor organ for hearing and is located in the mammalian cochlea. This highly varied strip of epithelial cells allows for transduction of auditory signals into nerve impulses’ action potential.
Which nerve transmits impulses from the spiral organ of Corti to the brain?
Hair cells in the organ of Corti (within the cochlea) are stimulated which in turn stimulates the cochlear branch of the vestibulocochlear nerve. 7. The cochlear nerve then transmits electrical impulses to the auditory region of the brain in the temporal lobe.
