Joe was examined by a nurse practitioner. She notes that the wound is approximately 1 cm deep, and there is exposed muscle tissue with areas of apparent tissue death. In addition, Joe's head and neck muscles are in a continuous spasm. They resist passive flexion and extension, and there is increased tone in his muscles of mastication and muscles of facial expression. The findings from the physical exam lead us to think that there may be more to this story than a simple wound infection. The continuous spasm of the muscles of the head, neck, and face indicates something potentially more serious. Remember that the muscular system is responsible for vital functions such as breathing, so any disturbance in skeletal muscle homeostasis must be closely monitored. Which of the following proteins associated with the myofilaments would be most involved in the muscle spasms?
A. TropomyosinB. TroponinC. TitanD. Actin
