Latin name

Group
Branchial arch muscle – second arch (Auricular muscle)
Etymology
The English name for this muscle is the greater muscle of the coil. Helicis comes from the Greek word helix meaning a “coil” and in this use designates the coil-like, rounded convex margin of the pinna (ear). The term major comes from the Latin maior meaning “greater.” As is typical in anatomical terminology, this comparative reference clues you into the fact that this is a larger version of a similar shaped smaller muscle.
Origin
Spine of the helix of the external ear.
Insertion
Anterior border of the helix of the external ear.
Action
Adjusts the shape of the auricle by depressing the anterior margin of the ear cartilage. While this is a potential action in some individuals, in the majority of individuals the muscle modifies auricular shape to a minimal degree.
Nerve supply
Facial nerve (Cranial nerve VII)
Blood supply
Auricular branches of the posterior auricular and occipital arteries.
Latin
Musculus helicis major
French
Grand muscle de l'hélix
