what statement/s is false about Neuronal Pathways for Olfaction
a. Axons from the olfactory neurons extend as olfactory nerves to the olfactory bulb, where they synapse with mitral and tufted cells.
b. The olfactory bulb neurons can modulate output to the olfactory tracts.
c. The olfactory tracts terminate in the sensory and temporal cortex. = sensory should be olfactory
d. The lateral olfactory area is involved in the conscious perception of smell, the intermediate area with modulating smell, and the medial area with visceral and emotional responses to smell.
what statement is true about Olfactory epithelium and bulb
a. Olfactory neurons in the olfactory epithelium are bipolar neurons. Their distal ends are enlarged as olfactory vesicles, which have long cilia.
b. The cilia have receptors that respond to dissolved substances. There are approximately 1000 different odorant receptors.
c. The receptors activate a G protein complex, which opens ion channels.
d. At least 7 (perhaps 50) primary odors exist. The olfactory neurons have a very low threshold and accommodate rapidly.
Which of the following structures is NOT part of the pathway by which olfactory signals reach the cortex?
A.
Olfactory epithelium
B.
Olfactory bulb
C.
Olfactory nerve
D.
Amygdala
E.
All of the above are part of a pathway through which olfactory signals reach the cortex
