From: Canine olfactory detection and its relevance to medical detection
Characteristics | Dog |
---|---|
Airflow | A sniff creates unique unidirectional laminar airflow patterns to transport environmental odorants to the olfactory epithelium [122] |
Size of olfactory mucosa | 95–126 cm2 (German Shepherd) [124] |
Olfactory genes in genome |  > 1000; 80% functional receptor genes and 20% pseudogenes [125] |
Amount of olfactory receptor cells (ORCs) | |
Cilia per ORC | 20 to 100 cilia per cell [58] |
Extent, shape and position of olfactory bulb | Proportionally larger than in humans and prominently at the ventro-rostral area of the brain [126] |
