Anatomy & Physiology: Muscles—Auricularis Group.
Structure.
- Auricularis Anterior
- Origin: temporal fascia/galea aponeurotica (lateral margin).
- Insertion: major helix/spine of helix (ear).
- Auricularis Superior
- Origin: temporal fascia/galea aponeurotica (lateral margin).
- Insertion: superior (to the ear) aspect of cranial surface.
- Auricularis Posterior
- Origin: the mastoid area of the temporal bone.
- Insertion: ponticulus (ridge) of eminentia conchae.
Function.
- Concentric action: brings/draws the ear anteriorly (auricularis anterior); elevates ear (auricularis superior); brings/draws ear posteriorly (auricularis posterior).
- Reverse mover action:
- Eccentric action:
- Isometric action:
- Innervation: facial VII nerve.
- Arterial supply: superficial temporal and posterior auricular arteries.
Clinical Significance.
