The tragicus, also called the tragus muscle or Valsalva muscle, is an intrinsic muscle of the outer ear.
It is a short, flattened vertical band on the lateral surface of the tragus.
While the muscle modifies the auricular shape only minimally in the majority of individuals, this action could increase the opening of the external acoustic meatus in some.
