Anatomical terms of muscle |
The muscle is located on the cranial surface of the pinna. It consists of scattered fibers, partly tendinous and partly muscular, extending from the eminentia conchae to the prominence corresponding with the scapha.[1]
While the muscle modifies the auricular shape only minimally in the majority of individuals, it could help flatten the cranial profile of the auricular cartilage.[2]
The transverse muscle is developmentally derived from the second pharyngeal arch.[2]
