Procedure 1 Model Inventory for Skeletal Muscle and Skeletal Muscle Fibers Identify the following structures of skeletal muscle and skeletal muscle fibers on models and diagrams, using your textbook and this unit for reference. As you examine the anatomical models and diagrams, record the name of the model and the structures you were able to identify on the model inventory in Table 11.2.

Part A: Identify the specific proteins of skeletal muscle cells that are involved in the sliding filament mechanism of muscle contraction. For each protein, describe its role in muscle contraction. (2 marks) Part B: What would happen in the muscle cell if the action potential did not travel down the T-tubules? Your answer should show that you understand the specific events that occur leading up to the binding of calcium to troponin.

Using the following terms, describe the overall structure and organization of a skeletal muscle: muscle, fascicle, muscle fiber, myofibril, sarcomere, myofilament, epimysium, perimysium, endomysium. Would you consider a skeletal muscle to be highly organized? If so, what helps to maintain this organization? What is responsible for the striated appearance of skeletal muscle tissue? Conclude your description with a response to the following statement: The presence of connective tissue sheaths facilitates movement when skeletal muscles are stimulated to contract. Explain
