Olfaction Flashcards
These are the stem cells located between the bases of the supporting epithelial cells. Produces new olfactory sensory neurons.
Basal Epithelial Cells
Located in the connective tissue that supports the olfactory epithelium.
Produces mucus that is carried to the surface of the epithelium through ducts (exocrine)
Olfactory glands or Bowman’s glands
It dissolves odorants so that transduction can occur.
Mucus
Olfactory glands are innervated by ________ neurons within branches of the ______ nerve
parasympathetic neurons, facial (VII)
membrane protein that is simulated when the odorant binds to the olfactory sensory neuron
G protein
If depolarization reaches ______, a nerve impulse is generated along the axon of the olfactory sensory neuron.
threshold
what forms cAMP?
adenylyl cyclase
what opens the cation channel?
cAMP
What is added to the natural gas which provides olfactory warning of gas leaks?
methyl mercaptan
olfactory nerves pass through
cribriform foramina
contains ball-like arrangements called glomeruli
olfactory bulbs
the second order neurons of the olfactory pathway
mitral cells
the axons of the mitral cells form the
olfactory tract
What lobe is olfactory cortex?
Temporal lobe
Are the only sensations that reach the cerebral cortex without synapsing in the thalamus
olfactory sensations
