|
The technical term for the sense of hearing.
|
audition
|
|
|
The intensity (or amplitude) of a sound wave, measured in decibels.
|
loudness
|
|
|
The intensity or amount of energy of a wave, reflected in the height of the wave; the amplitude of a sound wave determines a sound's loudness.
|
amplitude
|
|
|
The unit of measurement for loudness.
|
decibel
|
|
|
The relative highness or lowness of a sound, determined by the frequency of a sound wave.
|
pitch
|
|
|
The rate of vibration, or the number of sound waves per second.
|
frequency
|
|
|
The distinctive quality of a sound, determined by the complexity of the sound wave.
|
timbre
|
|
|
The part of the ear that collects sound waves; consists of the pinna, the ear canal, and the eardrum.
|
outer ear
|
|
|
A tightly stretched membrane at the end of the ear canal that vibrates when hit by sound waves.
|
eardrum
|
|
|
The part of the ear that amplifies sound waves; consists of three small bones: the hammer, tha anvil, and the stirrup.
|
middle ear
|
|
|
The part of the ear where sound is transduced into neural impulses; consists of the cochlea and semicircular canals.
|
inner ear
|
|
|
The coiled, fluid-filled inner-ear structure that contains the basilar membrane and hair cells.
|
cochlea
|
|
|
The membrane within the cochlea of the ear that contains the hair cells.
|
basilar membrane
|
|
|
The hairlike sensory receptors for sound, which are embedded in the basilar membrane of the cochlea.
|
hair cells
|
|
|
The view that the basilar membrane vibrates at the same frequency as the sound wave.
|
frequency theory
|
|
|
The theory that different frequencies cause larger vibrations at different locations along the basilar membrane.
|
place theory
|
|
|
Technical name for the sense of smell.
|
olfaction
|
|
|
Technical name for the sense of taste.
|
gustation
|
|
|
Chemical signals released by an animal that communicate information and affect the behavior of other animals of the same species.
|
pheromones
|
|
|
The enlarged ending of the olfactory cortex at the front of the brain where the sensation of smell is registered.
|
olfactory bulb
|
|
|
The specialized sensory receptors for taste that are located on the tongue and inside the mouth and throat.
|
taste buds
|
|
|
The unpleasant sensation of physical discomfort or suffering that can occur in varying degrees of intensity.
|
pain
|
|
|
Specialized sensory receptors for pain that are found in the skin, muscles, and internal organs.
|
nociceptors
|
|
|
A neurotransmitter that in involved in the transmission of pain messages to the brain.
|
substance P
|
|
|
The theory that pain is a product of both physiological and psychological factors that cause spinal gates to open and relay patterns on intense stimulation to the brain, which percieves them as pain.
|
gate-control theory of pain
|
|
|
The technical name for the sense of location and position of body parts to one another.
|
kinesthetic sense
|
|
|
Sensory receptors, located in the muscles and joints, that provide information about body position and movement.
|
proprioceptors
|
|
|
The technical name for the sense of balance, or equilibrium.
|
vestibular sense
|
