Latin muscle parts
Branchial arch muscle – second arch (Auricular muscle)
In English, this muscle’s name is the muscle that is opposite the goat. The prefix anti- is Latin for opposed to, or opposite. The term tragicus (for tragus), which is the name for the cartilage flap the covers the opening to the ear, is from the Greek word tragos for “goat.” The early anatomists thought that the hairs that often grow out of the tragus resembled the scraggly hairs on the chin of the goat.
Lateral surface of the antitragus
Tail of the helix and the antihelix
Adjusts the shape of the auricle by pulling the antitragus and tail of the helix towards each other, helping to increase the opening into the external acoustic meatus. While this is a potential action in some individuals, in the majority of individuals the muscle modifies auricular shape to a minimal degree.
