DIET 4415 Study Guide - Final Guide: Greater Petrosal Nerve, Lingual Papilla, Olfactory Bulb
Document Summary
Only one cranial nerve allows us to smell, so if you have repeated sinus infections or head trauma you can damage this nerve. Also vulnerable to damage and aging-associated losses. People can"t truly lose taste (because 7. 9,10 nerves allow you to to taste) total ageusia is very rare. If someone says something tastes bas it is probably because they have a poor sense of smell. Taste system is rebundant so it is rare to lose sense of taste completely. Poor oral health further decreases ability to smell through mouth. Located: bridge between the mouth and nose. To the olfactory cortex, packing with overall flavor, and broader cortical regions for memory, emotion and appetite. Only 1 olfactory perception nerve for smell - very vulnerable. People rarely use their actual sense of taste. 3 cranial nerves carry the taste message from the oral cavity to the gustatory cortex (7, 9, 10)
