Muscular System - Structure and Function
This document provides an overview of the muscular system, starting with a case study of Tom, a young boy with Duchenne Muscular Dystrophy (DMD). It explains the functions of the muscular system, types of muscle tissue, and delves into the structure of muscle fibers, including the sarcomere and its components.
The document also explores the role of the dystrophin protein, its absence in DMD, and the genetic inheritance of this condition. Tom's prognosis and treatment options, including gene therapy, are discussed. The relationship between muscles and the nervous system is explained, focusing on the neuromuscular junction and the role of neurotransmitters. The energy source for muscle contraction, the effects of exercise on muscles, and the phenomenon of rigor mortis are also covered.
Finally, the document touches on various muscular system disorders and concludes with a crossword puzzle and diagrams for review.
