Week 3Bone paintingFor this exercise, youll be using plaster models of various limb bones Choose a pair of bones that between them form a limb joint. Using text books identify the muscles that operate that joint. Classify those muscles according to functional groups (see scheme presented in the Limb Muscles lecture, see also table below), and using the coloured white board markers provided, draw on the attachments for the muscles, using different colours to denote the different functional groups. Plaster is heavier than bone but is not as strong please take care not to break the models. Most of the models have some casting artefacts (join lines, etc.) you should be able to identify these as well. Many anatomy texts have figures showing muscle attachments, and there will be some print-outs for you to use.

Body paintingUse the body paints to detail the muscles of a limb (can be upper or lower limb) Work in small groups Use text book illustrations to identify muscles Make sure you identify surface anatomy features that indicate muscle positions and attachments You can colour code the muscles any way you choose; one possible scheme is the functional groupings used in in the Limb Muscles lecture (see also table below).

Functional anatomy As a follow up to the exercise in Week 2, survey the muscles of the limbs for muscle type. Which are parallel fibred, and which are pennate? For the pennated muscles, what is the fibre organisation (e.g. unipennate, bipennate, multipennate, etc.)? What pennation angle is present in each muscle? As a group, record your results so that they can be compiled next week Presenting your results: think of how best to do this. As a visual map, a table, or some other way? Discuss the pattern of muscle pennation that you find. What explanations for that pattern can you think of? How would you test your proposed explanations to see if they are accurate?
