Final answer:
The mucosa-covered projections from each lateral wall of the nasal cavity are the Nasal Conchae, which help warm, moisten, and clean the air that enters the nasal passages.
Step-by-step explanation:
The scroll-like, mucosa-covered projections that protrude medially from each lateral wall of the nasal cavity are called Nasal Conchae. There are three nasal conchae: the superior, middle, and inferior. The inferior nasal concha is an independent bone, and the superior and middle nasal conchae are parts of the ethmoid bone. These bony structures serve to increase the surface area of the nasal cavity, which helps to warm and moisten the air as it enters, and to trap particles and pathogens in the mucus that lines the nasal cavity.
