Back 1

True

Front 2

After sound waves pass through the auditory canal, they strike the tympanic membrane.

Back 2

Back 6

False; bones in mid-ear fail to transmit waves to cochella

Front 7

Opiates exert their pain relieving effects by their action in the periphery of the body.

Back 7

False; spinal cord and periaqueductal gray area whereas cannabinoids act mainly in periphery

Front 14

The malleus, incus, and stapes are small bones:

Front 15

The fact that the various parts of the basilar membrane are tightly bound together is problematic for which of the following?

Back 15

the place theory

Front 16

People with massive damage to the primary auditory cortex:

A sound shadow refers to:

Back 19

how much louder a high–frequency sound is for the ear closest to the sound.

Front 20

In the otolith organs, the otoliths are calcium carbonate particles that:

The sensory aspect of pain activates the ________ cortex, whereas the emotional aspect activates the ________ cortex.

Back 24

somatosensory, cingulate

Front 25

Endorphins:

Back 25

can interact with the same receptors as morphine.

Front 26

What process is predicted by the gate theory of pain?

Back 26
