What is the main function of the middle ear ossicles?
To transmit and amplify sound vibrations from the eardrum to the inner ear
What is the primary function of the inner ear structures such as the cochlea and semicircular canals?

Which theory of pitch perception suggests that different pitches are detected by different places along the cochlea's basilar membrane?
Place theory
According to the frequency theory of pitch perception, how are low-frequency sounds detected?
By the rate at which auditory neurons fire action potentials
What is one of the main differences between place theory and frequency theory in explaining pitch perception?
Place theory correlates pitch to a specific location, while frequency theory correlates pitch to neural firing rate
