The muscular system
To understand the structure, function and classification of muscles with focus on the
skeletal muscles.
Using my knowledge of origins and insertions I can explain which muscles are responsible
for the main movements of a sport of my choice.

Smooth, cardiac, skeletal, epimysium, perimysium, endomysium, actin, myosin, myofibril,
muscle fibre, sarcomere, origin, insertion, elasticity, contractility, hypertrophy, atrophy,
Frist of all lets discuss what you know already. Look through the rest of unit one and discuss what you already
know.
Let’s have a little introduction to the muscular system.

Now go to edmodo and complete the end of unit assessment. If you score more than 90% you can move
onto the next unit. Feedback will be given within 24 hours.
You will now conduct an experiment on the extensibility of muscle tissue.
