Quick Facts
Origin: Spine of helix.
Insertion: Anterior border of helix.
Action: Typically, no movement in humans.
Innervation: Temporal branches of facial nerve (CN VII).
Arterial Supply: Posterior auricular and superficial temporal arteries.
Origin
The helicis major muscle originates from the spine of the helix on the lateral surface of the auricle.
Insertion
The helicis major muscle consists of a thin vertically orientated band of muscle fibers and inserts into the anterior border of the helix on the lateral surface of the auricle.
Actions
In the human ear, the helicis major muscle may be capable of drawing the auricle forwards and upwards. However, it is rare that individuals can modify the shape and position of their external ears (Standring, 2016).
