How many muscles do you need to train to bring home all the grocery bags in one go? In this simulation, you will learn about the functions of the skeletal muscle system and how the muscles act together to create a movement. Discover how they attach to the bones using 3D interactive models and understand how their roles in functional groups allow you to perform even the most complicated dance moves. 

Research the skeletal muscles for a training app 

You have an important mission: help an innovative company prepare a personal training application by investigating the skeletal muscle system. Begin your research by discovering the properties and functions of skeletal muscles. Do you use your muscles for more things than just moving around?  

Identify muscles’ functions and attachment points

Continue your investigation by learning about skeletal muscles’ attachment points. Learn how muscles connect to the bones and tissues via origin and insertion points by using an interactive 3D skeletomuscular model of the upper arm. While working on the model, figure out the five golden rules of muscle movement and activity by observing their alignment with the bones and tissues and noticing the ways they can contract. Does the muscle contraction bring insertion and origin points closer together or further away from each other?

Build your own upper arm muscle system 

In the end, try to answer one important question: how do muscles work together to create a movement? Gather all your findings and use them to build the upper arm system. Identify the functional roles of the muscles, such as prime movers, antagonists, synergists, and fixators. Attach them in the correct places to make the elbow flex! Finally, share your findings with the company. Will your research make you never skip leg day again?
