The sense or act of hearing
# of complete wavelength that pass a point in a given time (ex: per second)
A tone’s experienced highness or lowness; depends on frequency
Chamber b/w the eardrum and cochlea containing 3 tiny bones -hammer, anvil, stirrup-that concentrates the vibrations of the eardrum on the cochlea’s oval window
Coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses
The innermost part of the ear, containing the cochlea, semicircular canals and vestibular sacs
The people hear different pitches because different sounds waves trigger activity at different places, determines a pitch by recognizing specific place that is generating neural signal
When the brain reads pitch by monitoring the frequency of neural impulses traveling up the auditory nerve.
Conductive hearing loss?
Problems with the mechanical system that conducts sound waves to the cochlea
Sensorineural hearing loss?
Damage to the cochlea’s hair cell receptors or their associated nerves
Converting sounds into electrical signals ands stimulating the auditory nerve through electrodes threaded into the cochlea
Sense of the position and movement of body parts
Monitor’s the head and body’s position and movement
Theory that the spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain
Principle that 1sense may influence another- smell of food
