Olfactory System Flashcards
What detects sense of smell
Olfactory receptors in nasal epithelium
Which bone has the Cribriform plate
Ethmoid bone
Olfactory bulb
Where first order neurone synapses with mitral cells —> synaptic glomeleruli
Location of olfactory tract
Inferior surfaces of frontal lobe
Anterior perforated substance
triangular area of grey matter bordered by the medial and lateral roots of the olfactory tract and the diagonal band of Broca.
The perforations allow for the passage of vasculature through the anterior perforated substance.
Pathway of olfactory of system
Nasal epithelium
Olfactory bulb
Olfactory tract medial and lateral striae
Lateral olfactory striae connects to
Uncus - primary olfactory cortex
Hippocampus
Thalamus- oribito-frontal cortex
Where is the primary olfactory cortex located
Uncus in temporal lobe
Medial olfactory striae connects to
Septal nuclei- hypothalamus —> limbic system
Where does the olfactory tract bifurcate
Anterior perforated substance
Function of medial olfactory striae
Emotional memory
Function of lateral olfactory striae
Initial recognition of smell
Following the olfactory system pathway, what comes after the olfactory bulb
Olfactory tract
