The discovery of two new elements (atomic numbers 113 and 115) was announced in February 2004. The arrangement and interactions between thin and thick filaments allows for the sarcomeres to generates force. The outer fascial covering of a nerve is called the epineurium (translates to on the nerve). The main function of the deep fascia is to support and protect muscles and other soft tissue structures. These muscles are divided regionally into three parts; interspinales cervicis, thoracis and lumborum. The deep layer contains the transversospinalis muscle group which is made up of the semispinalis, multifidus, and rotatores muscles. What are the layers of muscle from superficial to deep?
