In 1927, Heetderks [4] described the alternating turgescence of the inferior turbinates in 80% of a normal population. According to Heetderks, the cycle is the result of alternating congestion and decongestion of the nasal conchae or turbinates, predominantly the inferior turbinates, which are by far the largest of the turbinates in each nasal ...
In humans, the nasal cycle is the normal ultradian cycle of each nostril's blood vessels becoming engorged in swelling, then shrinking. The nostrils are separated by the septum. The septum can sometimes be deviated, causing one nostril to appear larger than the other. With extreme damage to the septum and columella, the two nostrils are no ...
The nasal cavity is divided into two cavities by the nasal septum, and each is accessed by an external nostril. [13] [1] The division into two cavities enables the functioning of the nasal cycle that slows down the conditioning process of the inhaled air. [21]

The mucous membrane is thickest, and most vascular, over the nasal conchae. It is also thick over the nasal septum where increased numbers of goblet cells produce a greater amount of nasal mucus. It is very thin in the meatuses on the floor of the nasal cavities, and in the various sinuses. It is one of the most commonly infected tissues in ...
Nasal spray. Injection. Intravenously (IV) Oral NAD supplements (NAD+, NADH, NR or NMN) are the most popular, according to the experts, as they are more accessible.
