![]() ![]() Now, let’s know the detailed anatomical features of the three different types of cartilage from the dog ear. With the help of other cartilages, it forms the cartilaginous portion of the meatus. In addition, the annular cartilage is a small incomplete ring that attaches to the bony external acoustic meatus. Again, the scutiform cartilage is a small quadrilateral shape that attaches to the cranial aspect of the base of the auricular cartilage. The auricular cartilage is large and forms the shape of the dog ear. In dog ear cartilage anatomy, you will find three types of cartilages – auricular, annular, and scutiform. The base of the dog pinna is broad and attaches to the external auditory process of the petrous temporal bone. You may find the blunt or pointed apex (vary with the dog breed) in the dog auricle or pinna. The upper and lower borders of the dog pinna are thick. On the other hand, the posterior surface of the dog pinna is convex that covers hairy skin. The cranial surface of the pinna of a dog is concave, ridged, and possesses the opening of the external ear. But the shape of the auricle or pinna of the dog varies with the breed. It is roughly an elongated funnel-shaped structure with two surfaces, two borders, a base, and an apex. The auricle or pinna is the externally visible part of the external ear of a dog. So, you may jump to the dog ear cartilage anatomy to know details about them. If you want to know the detailed anatomy of these structures from the dog ear, you may continue this article till the end.Īll these structures are from the auricular cartilage of the dog ear.
