| - | '''Wasabi''' is a member of the [[Brassicaceae]] family, which includes [[cabbage]]s, [[horseradish]], and [[Mustard plant|mustard]]. It is also called '''Japanese horseradish''', although it is not actually from the horseradish species of plants. Its root is used as a [[condiment]] and has an extremely strong flavor. Its hotness is more akin to that of a hot [[Mustard (condiment)|mustard]] than that of the [[capsaicin]] in a [[chili pepper]], producing vapours that stimulate the [[human nose|nasal]] passages more than the tongue. The plant grows naturally along stream beds in mountain river valleys in Japan. There are also other species used, such as ''W. koreana'', and ''W. tetsuigi''. The two main [[cultivar]]s in the marketplace are ''W. japonica'' 'Daruma' and 'Mazuma', but there are many others. | ||
| + | The visible part of the '''human [[nose]]''' is the protruding part of the [[face]] that bears the [[nostril]]s. The shape of the nose is determined by the [[ethmoid bone]] and the [[nasal septum]], which consists mostly of [[cartilage]] and which separates the nostrils. On average the nose of a [[male]] is larger than that of a [[female]]. | ||

| + | The nose has an area of specialised cells which are responsible for [[smelling]] (part of the [[olfactory system]]). Another function of the nose is the conditioning of inhaled air, warming it and making it more humid. Hairs inside the nose prevent large particles from entering the lungs. [[Sneezing]] is usually caused by foreign particles irritating the nasal mucosa, but can more rarely be caused by sudden exposure to bright light (called the [[photic sneeze reflex]]) or touching the [[external auditory canal]]. Sneezing is a means of [[Transmission (medicine)|transmitting infections]] because it creates [[aerosols]] in which the [[droplets]] can harbour [[microbes]]. | ||

The visible part of the human nose is the protruding part of the face that bears the nostrils. The shape of the nose is determined by the ethmoid bone and the nasal septum, which consists mostly of cartilage and which separates the nostrils. On average the nose of a male is larger than that of a female.
The nose has an area of specialised cells which are responsible for smelling (part of the olfactory system). Another function of the nose is the conditioning of inhaled air, warming it and making it more humid. Hairs inside the nose prevent large particles from entering the lungs. Sneezing is usually caused by foreign particles irritating the nasal mucosa, but can more rarely be caused by sudden exposure to bright light (called the photic sneeze reflex) or touching the external auditory canal. Sneezing is a means of transmitting infections because it creates aerosols in which the droplets can harbour microbes.
