Etymology
The English name of this muscle is the muscle of the hip and cuckoo. The word ischium has an interesting history. Hippocrates first used the Greek term ischion to designate both the “hip joint and the hip region.” It was later Latinized as ischium and used to describe “the lower bone of the os coxae.” The word coccygeus comes from the Greek kokkyx meaning “cuckoo,” because of the resemblance of the coccyx or tailbone to the beak of a cuckoo bird.
