The rhinarium is the rostral-most area of the snout that surrounds the nostrils, and is hairless in most mammals. In rodents, it participates in coordinated behaviors, active tactile sensing, and active olfactory sensing. In rats, the rhinarium is firmly connected to the nasal cartilages, and its motility is determined by movements of the rostral end of the nasal cartilaginous skeleton (NCS). Here, we demonstrate the nature of different cartilaginous regions that form the rhinarium and the nasofacial muscles that deform these regions during movements of the NCS. These muscles, together with the dorsal nasal cartilage that is described here, function as a rhinarial motor plant. Anat Rec, 296:1821-1832, 2013. (c) 2013 Wiley Periodicals, Inc.
