hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerves; the most common form of hearing loss, also called nerve deafness or sensorineural deafness
what is sensorineural hearing loss?
a part of the somatosensory system concerned with the perception of hotness and coldness; touching nearby warm and cold spots produces the sensation of hot
what is warm and cold receptors
the innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs.
What is the inner ear?
the feeling that an amputated limb is still present, often manifested as a tingling or, occasionally, painful sensation.
what is phantom limb?
the ability to identify the position and changes in position of sound sources based on acoustic information.
what is sound localization
a tone’s experienced highness or lowness; depends on frequency
what is pitch?
What animal only has 1 ear?
what is a praying mantis
the theory that the spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain.
what is gate-control theory?
in hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch. Also called temporal theory
what is frequency theory?
the sense or act of hearing sound, the movement of air molecules at different wavelengths and amplitudes
what is audition?
a set of three looped tubular channels in the inner ear that detect movements of the head and provide the sense of dynamic equilibrium that is essential for maintaining balance.
what is semicircular canals?
the sense of smell, processed by the olfactory system; airborne molecules attach to receptors in the nasal cavities, which send messages to the brain’s olfactory bulb for processing
what is olfaction?
the principle that individual fibers in an auditory nerve respond to one or another stimulus in a rapid succession of rhythmic sound stimuli, whereas other fibers in the nerve respond to the second, third, or nth stimulus
what is volley theory?
in hearing, the theory that links the pitch we hear with the place where the cochlea’s membrane is stimulated
what is place theory
the chamber between the eardrum and cochlea containing three tiny bones that concentrate the vibrations of the eardrum on the cochlea’s oval window
What is the middle ear?
one of the senses of taste associated with savoriness, corresponding to the flavor of glutamates, especially monosodium glutamate.
what is umami?
a less common form of hearing loss, also known as conduction deafness, caused by damage to the mechanical system that conducts sound waves to the cochlea
what is conduction hearing loss
clusters of gustatory cells found on taste buds throughout the oral cavity on hard and soft palates, tonsils, pharynx, and epiglottis, but they are most numerous on the tongue
what are taste receptors
a coiled, bony, fluid-filled tube in the inner ear; sound waves traveling through the cochlear fluid trigger nerve impulses.
what is the cochlea?
a condition in which stimulation of one sense generates a simultaneous sensation in another.
what is synesthesia?
