An elderly lady is brought to the emergency room after drinking
insecticide that she thought was tea. After her stomach is pumped,
her sense of smell is tested and it is found that she can not distinguish
common smells (e.g., an orange, coffee). CT scan of the head demonstrates
a mass in the olfactory groove area. The axons likely compressed by this
mass project to which of the following structures?
A. Insula
B. Nucleus ambiguus
C. Post-central gyrus
D. Pre-central gyrus
E. Pyriform cortex
