M3L3 Hearing

a structural element that divides the cochlea into two liquid-filled tubes.

• Cochlea
• Ossicles
• Oval window
• Basilar membrane

hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea

• Auditory nerve

• Place theory

• Conduction deafness

• Sensorineural deafness

an extension of frequency theory, which proposes that when peaks in a sound wave come too frequently for a single neuron to fire at each peak, several neurons fire as a group at the frequency of the stimulus tone.

• Pitch theory

• Volley theory

• frequency theory

• Place theory

A narrow region leading from the outside of the human ear to the eardrum.

• cochlea
• ear canal
• auditory nerve
• oval window

A sensory characteristic of sound produced by the amplitude (intensity) of the sound wave

• Pitch
• Basilar Membrane
• Loudness
• Timbre

three tiny bones in the middle ear: malleus, incus, stapes

• Basilar Membrane
• Oval Window
• Cochlea
• Ossicles

a coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses

• Ossicles

• Oval Window

• Cochlea

• Basilar Membrane

in hearing, the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated

• Conduction deafness

• Pitch

• Volley theory

• Place theory

Loss of the ability to hear because of impairment of the cochlea, auditory nerve or auditory cortex.

• Nerve deafness / sensorineural hearing loss

• ear cilia / hair cells

• Loudness

• Eardrum / tympanic membrane

when they are physically knocked over, transduction occurs for sound, sends signals to the auditory nerve

• Conduction deafness

• Auditory nerve

• Eardrum / tympanic membrane

• ear cilia / hair cells
