You will find an oval to elliptical thin, slightly opaque membranous partition (tympanic membrane or eardrum) between a cat’s ear’s external acoustic meatus and tympanic cavity. The outer part of the ear is cupped shaped (known as auricle or pinna) and consists of scutiform cartilage and intrinsic and extrinsic muscles.Īn external auditory meatus (ear canal) extends more or less ventrally and turns essentially medially to the tympanic membrane.
But, you will learn more about these features of cat’s ear with the labeled diagrams. Here, I will enlist some of the special features from the cat’s ear. Now, you may learn the details anatomy of these three regions of a cat’s ear.
