Module 10.1: Overview of Muscle TissueModule 10.1 in your text looks at the basic properties that are common to all types of muscle tissue. By the end of this module, you should be able to do the following:1.Describe the major functions of muscle tissue.2. Nameand describe the structural elements and properties common to all types of muscle cells.3.3.Compare and contrast the characteristics of skeletal, cardiac, and smooth muscle tissue.Build Your Own GlossaryFollowing is a table with a list of key terms from Module 10.1. Before you read the module, use the glossary at the back of your book or look through the module to define the following terms.Key Terms for Module 10.1TermDefinitionEndomysiumMuscle fiberMuscle tensionSarcoplasmSarcolemmaMyofibrilSarcoplasmic reticulumContractilityConductivityElasticity110Muscle Tissue and Physiology
2Active-Learning WorkbookIdentify It: The Types of Muscle TissueIdentify the type of muscle tissue shown in each of the following micrographs in Figure 10.1. Explain for each micrograph what features of the tissue led you to the correct identification.Figure 10.10.1 Three types of muscle tissue.Key Concept:What is the function of all types of muscle tissue? What structural properties do they all share?Module 10.2: Structure and Function of Skeletal Muscle FibersThis module in your text examines the structure of skeletal muscle fibers at the cellular and chemical levels of organization. When you finish this module, you should be able to do the following:1.Describe the structural properties and components of a skeletal muscle fiber.2.Explain the organization of a myofibril.3.Describe the structure and components of thick, thin, and elastic filaments.4.Name and describe the function of each of the contractile, regulatory, and structural protein components of a sarcomere.5.5.Explain the sliding-filament mechanism of muscle contraction.Build Your Own GlossaryFollowing is a table listing key terms from Module 10.2.
