the olfactory system
The Olfactory System
  • Olfactory receptors line nasal epithelium, axon extends through pores in bones of skull, dendrite has branches, olfactory cilia that contain receptor proteins for odorants, protected by a thin layer of mucus
olfactory system
Olfactory System
  • Receptors send axons to olfactory bulb, in primates lies over nose, in other vertebrates posterior to nose
  • Axons from olfactory bulb enter brain via olfactory tract, project to primary olfactory cortex or pyriform cortex on anterioventral of anterioventral of telencephalon, no passage through thalamus
  • Taste is one of the five senses used by the brain to distinguish certain aspects of the natural world, and discern poisons and unhealthy foods
  • The main instrument used to taste is the tongue
  • However, recognition and memory also plays a role in taste
the tongue
The Tongue
  • The tongue has clusters of taste-receptor cells in taste buds.
  • Taste buds are organized into five groups of sensors:






taste buds
Taste Buds
  • Gustatory receptors found on the tongue, throat, and oral lining (primarily the cheeks)
  • Taste pores cluster together to form taste buds
  • Each receptor is connected through a synapse to at least one sensory neuron leading to the back of the brain
how is flavor recognized
How Is Flavor Recognized?
  • Collaboration of taste, smell, and the brain
  • Sensed by taste sensations, food temperature, texture, and odor.
what causes smell and taste disorders
What Causes Smell and Taste Disorders?
  • Aging or birth defects
  • Several other causes such as laryngitis and smoking
disturbance of smell
Disturbance of Smell
  • Transport olfactory loss
  • Sensory olfactory losses
  • Others including specific anosmia and and partial anosmia
effects of disorders
Effects of Disorders
  • Loss of senses
  • Loss of ability to distinguish flavor
how to diagnose disorders
How to Diagnose Disorders
  • Several easy tests, such as the “scratch-and-sniff” test and the “sip, spit and rinse” test.
  • Several treatments to improve conditions
  • No proper medication
