Describe olfactory neurons and explain how airbornemolecules can stimulate action potentials in olfactorynerves
Fill in the blank:
A chemical would be considered _______________________ if a person lacks a particular receptor site on the cilia of the olfactory neurons.
what statement is false 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.
