Corrugator Coiterii

(From corrugo, to wrinkle). Volcherus Coiter first took notice of these muscles. The corrugator arises fleshy from the internal angular process of the os frontis, above the joining of the os nasi, and the nasal process of the maxillary bone; from thence it runs outwards, and a little upwards. It is inserted into the inner and inferior fleshy part of the occipito-frontalis muscle, where it joins with the orbicularis palpebrarum, and extends outwards as far as the middle of the superciliary ridge. When one of these muscles acts, it draws the eye brow of that side towards the other; and makes it project over the inner canthus of the eye: when both act, they pull down the skin of the forehead, and make it wrinkle, particularly between the eye brows. This muscle is called by Winslow musculus supercilii; by Douglas, frontalis varus musculus: and by Riolan, carnosa musculosa membrana.

Corycomachia

And Corycus, (from a ball, and contention).
