11.2 - Movement
Assessment statements
| DCS Topic Code | Statement | Guidance |
| 11.2.U1 | Bones and exoskeletons provide anchorage for muscles and act as levers. | |
| 11.2.U2 | Synovial joints allow certain movements but not others. | |
| 11.2.U3 | Movement of the body requires muscles to work in antagonistic pairs. | |
| 11.2.U4 | Skeletal muscle fibres are multinucleate and contain specialized endoplasmic reticulum. | |
| 11.2.U5 | Muscle fibres contain many myofibrils. | |
| 11.2.U6 | Each myofibril is made up of contractile sarcomeres. | |
| 11.2.U7 | The contraction of the skeletal muscle is achieved by the sliding of actin and myosin filaments. | |
| 11.2.U8 | ATP hydrolysis and cross bridge formation are necessary for the filaments to slide. | |
| 11.2.U9 | Calcium ions and the proteins tropomyosin and troponin control muscle contractions. | |
| 11.2.A1 | Antagonistic pairs of muscles in an insect leg. | |
| 11.2.S1 | Annotation of a diagram of the human elbow. | Elbow diagram should include cartilage, synovial fluid, joint capsule, named bones and named antagonistic muscles. |
| 11.2.S2 | Drawing labelled diagrams of the structure of a sarcomere. | Drawing labelled diagrams of the structure of a sarcomere should include Z lines, actin filaments, myosin filaments with heads, and the resultant light and dark bands. |
| 11.2.S3 | Analysis of electron micrographs to find the state of contraction of muscle fibres. | Measurement of the length of sarcomeres will require calibration of the eyepiece scale of the microscope. |
