In rats, the VNO is located in a cigar-shaped passage in the floor of the nasal cavity, right next to the septum, with a narrow opening just inside the nostril. This dead-end position means that air can't flow into it, like the olfactory epithelium of the nose (Agosta 1992).

2022年2月1日 · In this study, we present a detailed flow analysis using an anatomically accurate rat nasal cavity model, in which the anatomy and physiology of the nasal airway was thoroughly examined.

2018年4月30日 · In the case of mice and rat's OM-MSCs, knowledge about the anatomy and histology of their nasal cavity is essential in establishing effective collection protocols. The present article describes the morphological characteristics of rodent's OM and establishes an alternative protocol for access to the olfactory recess and collection of the OM ...

2024年6月1日 · An important difference between the respiratory physiology of rats and humans is that rats are obligate nose breathers, due to the close apposition of the epiglottis to the soft palate, whereas humans can breathe through the mouth and/or nose (i.e., oronasal breathing) due to the arrangement of their nasal and oral cavities relative to the ...

2015年11月1日 · The nose is a structurally and functionally complex organ with multiple functions that include olfaction, warming, humidifying and filtering of the inspired air (Negus, 1958, Proctor and Andersen, 1982, Proctor and Chang, 1983).

2017年3月6日 · Active sampling of touch and smell involves coordinated movements first observed in the rat half a century ago. A new study has unveiled the elegant choreography of this facial and head motion during tactile and olfactory exploration.

(A) Sagittal view of the reconstructed 3D model of the left side rat nasal cavity with the global grids. The anterior is external naris, the posterior is nasopharynx and the post-dorsal part is...

The rodent nose is a structurally complex organ with multiple functions. Besides housing the essential components of the olfactory system, the nasal passages filter, humidify, and warm the inspired air preparing it for the delicate gas exchange tissues in the lung.

2021年12月21日 · In this study, we present a detailed flow analysis using an anatomically accurate rat nasal cavity model, in which the anatomy and physiology of the nasal airway was thoroughly examined. Special efforts were given to the swirling flow structures in the nasal vestibule (anterior section of the nose, …

Nasal airway model of a Sprague–Dawley rat (80): (A) life-size and scaled rat nose models of a Sprague–Dawley rat compared to a penny, (B) rat nose and anatomy and different functional...
