Nasal membrane
The human nasal (perinasal) membrane is a thin, thin film of epithelium that covers the entrance to the nasal cavity. It is a cross between the skin and the mucous membrane.
However, this name comes from another organ of the oral cavity, namely the rhinoceros. Although only humans and Asian elephants now have rhino-oral organs, many animals once had them. Maple monkeys, crocodiles and dinosaurs also had rhinos, which they used to get food. For example, paroxinal mammals began to eat the ground after the first rains and easily dug up grain for themselves, thus destroying the floor on it.
The rhinooral organs are responsible for the reception of olfactory sensations. They are localized on the outer side of the nasal palate
