PSYC326 Quiz 3: Chapter 7

Terms in this set (28)

pitch
determined by the frequency of vibration (measured in hertz)
loudness
degree to which the compressions and expansions of air differ from each other - more vigorous vibrations produce more intense (louder) sound waves
timbre
provides info about the nature of the particular sound - mixture of different frequencies of vibration
pinna
external ear; funnels sound through ear canal to tympanic membrane
tympanic membrane
eardrum; vibrates with the sound
ossicles
bones of the middle ear, set into vibration by the tympanic membrane
malleus (hammer)
connects with the tympanic membrane and transmits vibrations via the incus and stapes to the cochlea
cochlea
structure in inner ear that contains the receptors
oval window
membrane at the entrance to the cochlea through which the ossicles transmit vibrations (separates middle and inner ear)
organ of Corti
basilar membrane, hair cells, and tectorial membrane
hair cells
auditory receptor cells
Deiters' cells
anchor hair cells to basilar membrane
basilar membrane
membrane supporting the organ of Corti and hair cells in the cochlea
tectorial membrane
located above the basilar membrane; serves as a shelf against which the cilia of the auditory hair cells move
round window
allows fluid in the cochlea to move
cutaneous senses
system of receptors located in the skin that provides information about touch, pressure, pain, and temperature
proprioception
ability to tell where one's body is in space
kinesthesia
awareness of positioning of body parts and body movement
organic senses
arise from receptors in and around internal organs
glabrous skin
hairless skin; found on the palms and soles of the feet
Merkel's disks
detection of form and roughness, especially by fingertips
Ruffini corpuscles
detection of static force against skin, skin stretching, proprioception
Meissner's corpuscles
detection of edge contours, Braille-like stimuli, especially by fingertips
Pacinian corpuscles
detection of vibration, info from end of elongated object being held (like a tool)
hair follicle ending
detection of movement of hair
free nerve ending (hairy and glabrous skin)
detection of thermal stimuli, noxious stimuli, tickle
free nerve ending (hairy skin)
detection of pleasurable touch from gentle stroking with soft object
mechanoreceptors
detect stimuli that cause vibration in the skin or changes in pressure against it
