1. The olivary nuclei, inferior colliculi, and medial geniculate nuclei are structures of the

somatosensory system
auditory system
olfactory system
visual system

2. The analgesic effects of morphine are thought to be largely mediated by its action on

raphé neurons
PAG neurons
dorsal column neurons
anterolateral pathway neurons

3. The theory that all tastes can be produced by a combination of four primaries (sweet, sour, salty, and bitter) is

accepted by most researchers who study taste
is consistent with only some of the evidence
based on the discovery that there are four kinds of taste receptors
accepted by virtually all researchers who study taste

4. The receptive structure of the ear for sound is located within the

outer ear
tympanic membrane
middle ear
Organ of Corti

5. The transduction of sound differs from that of light in that

photoreceptor activation is a mechanical process
photoreceptor activation leads to receptor depolarization
activation of auditory receptors is a biochemical process
auditory receptor activation leads to receptor depolarization

6. High frequency pitch is detected by

vibration of different portions of the tympanic membrane
vibration of different portions of the basilar membrane
the synchronization of firing rates of different neurons within the acoustic nerve
the rate of firing of neurons within the acoustic nerve

7. Which of the following is a function of the vestibular system

adjusting eye movements to compensate for head movements
keeping the head upright
maintaining balance
all of the above are correct

8. Painful stimuli are detected by ______ in the _______.

Pacinian corpuscles; sheaths around tendons
Ruffini corpuscles; within the teeth
Merkel’s disks; skin
Free nerve endings; skin

9. Flavor refers to

the intensity of an olfactory stimulus
a combination of gustatory and olfactory qualities
the pattern of responses produced by odorants on the tongue
the intensity of a gustatory stimulus

10. The fact that sound from the side of our head reaches our two ears at different times provides evidence for the existence of

an opponent-process theory
a sound shadow
frequency theory
place theory
