Extending from the external face of the scutiform cartilage to the inner side of the concha, and generally composed of two fasciculi, it is covered by the skin and the conchal band of the external temporo-auricularis, while it covers part of the internal scuto-auricular muscle. Fiff. MUSCLES OF THE EAR. 1, Cervico-auricularis superficialis; 2, Temporo-auricularis internus; 3, 4, Tem- poro-auricularis externus ; 5, Scutiform cartilage ; 6, Scuto-auricularis externus; 7, Posterior auricular artery ; 8, Portion of the zygomatico-auricularis ; 9, Orbital process; 10, Temporo-auricularis internus; 11, Temporal muscle; 12, Scutiform cartilage; 13, Ditto ; 14, Concha of the ear ; 15, Scuto-auricularis externus; 16, Internal scuto-auricularis ; 17, Parotido-auricularis ; 18, Corrugator supercilii; 19, Zygomatico-auricularis. When this muscle contracts, it principally participates in producing the rotatory movement that carries the opening of the concha outwards. 4. Cervico-auriculares.—(Percivall apparently makes one muscle of these three—the retrahentes aurem; Leyh designates them as the cervico- auriculares externus, medius, and internus. (Fig. 396). Three in number, and situated behind the ear, these muscles are broad, thin bands, extending from the cervical ligament to the conchal cartilage. With regard to their superposition at their origin, they may be distinguished as superficial, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these i
