Olfaction
Olfaction
The sense of smell, where receptor cells in the nasal cavity detect airborne molecules and send signals to the brain.
Odorant Receptors
Odorant Receptors
Specialized proteins in the nasal cavity that bind to and activate by specific odor molecules.
Olfactory Bulb
Olfactory Bulb
A brain structure that receives neural signals from the olfactory receptors and relays them to the brain.

Study Notes
Olfaction
- Olfaction, or the sense of smell, works through receptor cells in the olfactory membrane of the nasal cavity
- Odorant receptors in the nasal cavity are activated by specific molecules in the air
- Activated receptors send signals to the brain through the olfactory bulb
- The olfactory cortex processes this information and perceives it as smell
- Olfaction is unique as it is the only sense not initially processed by the thalamus
- Pheromones, chemical signals, influence behavior and physiology of other members of the same species, often related to mating behaviors
Gustation
- Six types of taste exist: salty, sweet, bitter, sour, umami (savory), and oleogustus (fatty)
- Taste buds, located on bumps across the tongue, detect food molecules
- A single bump contains approximately 200 taste buds
- Each taste bud has 50-100 taste receptor cells
- Taste sensitivity varies between individuals (supertasters, medium tasters, non-tasters)
- Texture and smell also impact the taste experience
- Taste can be dulled or muted if the sense of smell is obstructed
