Frontoscutular muscle

Musculus frontoscutularis

  • Synonym: Frontoscutularis muscle

Definition

Marjorie Champarou

The frontoscutularis muscle extends from the zygomatic process of the frontal bone to the adjacent temporal line in caudal direction (or even on the superciliary arch in rabit) to the scutiform cartilage. In the carnivore and pig, it joins the frontoscutularis muscle on the opposite side in a thin transverse band with dissociated fibers. It seems to prolong rostrally the interscutularis muscle.

Origin: zygomatic process of the frontal bone and adjacent temporal line

Insertion: the medio-rostral border and the superficial face of the scutiform cartilage

Artery: rostral auricular artery

Nerve: auriculopalpebral nerve

Action: it pulls the scutiform cartilage rostrally

Antagonist: Cervicoauricularis muscles
