Connection to Brain
100
Are the sensory receptors of both the auditory system and the vestibular system in all vertebrates.
What is a Hair Cell? http://upload.wikimedia.org/wikipedia/commons/thumb/9/9b/Organ_of_corti.svg/2000px-Organ_of_corti.svg.png http://www.advancedhearingaidclinic.com/hearing-loss/images/hair_cell.jpg
100
This sense is caused by vibrations called sound waves cause particles in the air to vibrate.
What is hearing?
100
To detect sound and recognize it in space.
What is the role of hair cells?
100
The cell's connection to the brain is part of this body system.
What is the nervous system.
200
This is the location of the cell.
What is the cochela?
200
By generating nerve impulses in the auditory nerve and sending them to the brain.
What is the hair cells response to waves?
200
The movement of fluid pushes on a structure called cupula that transduce the mechanical movement to electrical signals
What is the way the hair cell is activated?
200
The hair cell sends electrical signals through these.
What are nerve fibers?
300
Amplify sound waves and transduce auditory information to the Brain Stem
What is the function?
300
Found only in mammals, is in the cochlear duct, of the cochlea of the inner ear and is provided with hair cells or auditory sensory cells.
What is the organ of corti?
300
Is the sensory system that provides the leading contribution about movement and sense of balance.
What is The Vestibular System?
300
These pathways carry information from the hair cells to the nervous system.
What are afferent pathways?
400
Nerve fibers that carry information to the brain contact only the inner hair cells.
What is inner hair cells?
400
Only one row in the organ of corti.
What is the number of inner hair cells?
400
A cluster of these lie at the base of all three canals.
What are sensory hair cells?
400
Nerve impulses in the inner ear travel along this.
What is the vestibulocochlear nerve
500
Located near the center of the basilar membrane where vibrations will be greatest while the basilar membrane is anchored under the inner hair cells
What is outer hair cells?
500
Only three rows in the organ of corti.
What is the number of outer hair cells?
500
Ability to be aware of oneself in space.
What is spatial awareness?
500
The movement of these convert vibrations into nerve impulses.
