Researchers-find-a-new-muscle-layer-in-t

Scientists recently uncovered a part of the body that had never been described before: a deep layer of muscle in the masseter, which raises the lower jaw and is critical for chewing.

Modern anatomy textbooks describe the masseter muscle as having two layers, one deep and one superficial. "However, a few historical texts mention the possible existence of a third layer as well." Through exmaninations of human cadaver skulls, they identified an "anatomically distinct" layer of the masseter muscle. 

"Although it's generally assumed that anatomical research in the last 100 years has left no stone unturned, our finding is a bit like zoologists discovering a new species of vertebrate," senior author Dr. Jens Christoph Türp, a professor and clinician at the University Center for Dental Medicine Basel, said in the statement.
