1. What is the least complex special sensory system?
a. Olfactory system
2. What is the olfactory system responsible for?
a. smell
3. What is the most complex special sensory system?
a. Hearing and balance
4. Where are the receptors located in the olfactory system?
a. In the olfactory epithelium on the upper part of the nasal cavity
5. What do the olfactory cilia do?
a. Non motile, site of olfactory transduction,where chemoreceptors are located,
covered in mucus
6. What is the purpose of the mucus covering the olfactory cilia?
a. Moisten and protect
b. Dissolves odorant molecules
7. What is the name for the smell molecules?
a. Odorant
8. What is unique about basal cells in the olfactory system?
a. Do make new olfactory cells every few months, one of the few places we make
new neurons
9. What kind of receptor is the olfactory receptor?
a. G coupled protein receptor
10. Olfactory is the only sense that does not pass through the where first?
a. Thalamus
11. What is the threshold for olfactory smell?
a. Low threshold, very little odorant needed
12. What is the adaptability of the olfactory system?
a. Fast adapting, adapt 50% in the first second, gets much less sensitive quickly
13. What is the taste sensory system called?
a. Gustatory system
14. Where is each receptor for taste held?
a. Chemoreceptors in single papillae on tongue
15. What is the name for the chemicals that cause taste?
a. Tastant
16. What is the chemical that breaks down molecules to be tasted?
a. Saliva
17. What are the five taste profiles?
a. Salty
