CN I Flashcards
Primary sensory neurons are
bipolar
Primary sensory neurons are found
in olfactory epithelium
Primary sensory neurons are surrounded by
supporting cells
Olfactory epithelium is covered by
a thin layer of mucus
T/F - Olfactory nerves are myelinated
False, but they are covered by Schwann cells
Primary sensory neurons pass through
cribriform plate of ethmoid bone
Primary sensory neurons synapse with
Dendrites of secondary sensory neurons (mitral cells)
Where do the primary sensory neurons synapse with the dendrites of the mitral cells?
Synaptic glomeruli
Mitral cell bodies are located in
olfactory bulb
Where do mitral cells split?
Anterior perforated substance
Mitral cells travel posteriorly via
olfactory tract
Medial stria fibers travel
across the midline to the opposite olfactory bulb
Lateral stria fibers travel
to primary olfactory cortex
Primary olfactory cortex is located
in the medial aspect of the temporal lobe
Specific areas of the brain that information from the olfactory nerves travels to
Periamygdaloid area
Prepiriform area
Brodman area 34 (uncus)
