It forms a large band, together with the parietoauricularis muscle, that originates on the caudal part of the temporal line (pig, rabbit) or the external sagittal crest (horse, carnivores). It detaches from the parietoauricularis muscle to insert on the scutiform cartilage.
Origin: caudal part of the temporal line (pig, rabbit), external sagittal crest (horse, carnivore), behind the intercornual protuberance, close to the middle part of the parietal bone (ruminants)
Insertion: in ruminants, the carnivore and rabbit, caudal end of the scutiform cartilage
Artery: caudal auricular artery
Nerve: caudal auricular nerve
Action: it raises the concha of auricle
