El cuádriceps tiene un quinto músculo

The quadriceps is one of the most important muscle groups in the body, located on the front of the thigh. It is very powerful and has a large volume. Until now, we had been told that the quadriceps was composed of four heads or muscle bellies. However, in 2016, K. Grob et al. reported the discovery of a fifth muscle. https://pubmed.ncbi.nlm.nih.gov/26732...
