The Tragicus (muscle of tragus 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.The helicis major is developmentally derived from the second pharyngeal arch.
