PRODUCT DESCRIPTION

This powerpoint presentation covers Topic 11.2 (HL Muscles & Movement) in the IB Biology curriculum. Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes.

The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!


**IB Biology Learning Objectives

11.2.1 – State the roles of bones, ligaments, muscles, tendons and nerves in human movement.

11.2.2 – Label a diagram of the human elbow joint, including cartilage, synovial fluid, joint capsule, named bones and antagonistic muscles (biceps and triceps).

11.2.3 – Outline the function of the structures in the human elbow named in 11.2.2.

11.2.4 – Compare the movement of the hip and the knee joint.

11.2.5 – Describe the structure of striated muscle fibers, including the myofibrils with light and dark bands, mitochondria, the sarcoplasmic reticulum, nuclei and the sarcolemma.

11.2.6 – Draw and label a diagram to show the structure of a sarcomere, including Z lines, actin filaments, myosin filaments with heads, and the resultant light and dark bands.

11.2.7 – Explain how skeletal muscle contracts, including the release of calcium ions from the sarcoplasmic reticulum, the formation of cross-bridges, the sliding of acting and myosin filaments, and the use of ATP to break cross bridges and re-set myosin heads.

11.2.8 – Analyze electron micrographs to find the state of contraction of muscle fibres.
