Muscle Contraction Lab

Satisfactory Essays
In order for us to move, our bodies utilize its muscles to create movement. Muscles help with maintaining body temperature, supporting of soft tissue and skeletal movement. To do this, muscles must be able to contract during each movement. This lab session was completed in order for us to have a greater understanding of how muscles function and to find the relationship between muscle length and force. To better understand what events occur during muscle contraction, an electromyogram (EMG) was used to record the electrical activity of contracted forearm flexors at different angles of the wrist.
In this experiment, one of our lab partners was connected to the electromyogram. He then had to flex his wrist at four different angles while squeezing
