Definition

Marjorie Champarou

The cervicoauricularis superficialis muscle is a fleshy muscular blade, relatively long and narrow in ruminants and pig, or larger at its origin and narrowed at its rostro-medial end in the horse and the carnivore. It is extended from the nuchal crest or the nuchal funiculus (ruminants) to the base of the concha of auricle.

Origin: external occipital protuberance and adjacent part of the nuchal ligament cord or cervical raphe

Insertion: base of the medio-caudal side of the cartilage of the auricle

Artery: caudal and occipital auricular arteries 

Nerve: caudal auricular nerve

Action: it pulls the concha of auricle in a medio-caudal direction and allows its raising

Antagonist: parotidoauricularis muscle
