6. Identify each of the following structures when given images of skeletal muscle fibers such as the one below. an entire muscle fiber myofibril ● ● myofilaments ● sarcolemma ● sarcoplasm • sarcoplasmic reticulum ● transverse tubules cisternae ● ● triad

explain the inner cells of the skeletal muscle to include: myofibrils, sarcolemma, sarcoplasm

9. Explain the process that occurs to generate a muscle contraction. Name the four major stages and be able to describe the events that happen at each stage.

22. There are three types of muscle fibers, which differ in terms of how fast they contract and how they get ATP. For each statement below, write the fiber type that matches the description: Look white: A2su ovibennoo senab ni baqqstw a16 er 2lonud o Contract slowly: Copin 2:boold qmug of viivon vsd senboo • ATP supplied by aerobic respiration: abiovom C viivi and Low resistance to fatigue: d vo Would be well developed in an Olympic sprinter: lo abol
