Muscle parts

Latin name

Musculus helicis major

Latin muscle parts

None

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
