Ans: The lateral wall in the nasal cavity consists of 2 different curved bones which are termed conchae. These inferior bones are medially projected. The combination of the middle concha and the superior concha results in the formation of the ethmoid bone. However, the inferior concha is a separate entity. There is also another normal variant known as the supreme conchae. One of the main functions of the conchae is to ensure that the air inspired by the nose stays humidified. It also acts in increasing the surface area of the nasal chamber. This lateral wall of nose diagram will help students understand the concept better.
