Back

Involuntary muscles control functions that are not consciously directed, such as heartbeats and digestion.

Front

What is the difference between voluntary and involuntary muscles?

Front

What is the gastrocnemius muscle?

Back

The gastrocnemius is a major calf muscle that helps in plantar flexion of the foot and flexion of the knee.

Front

What is the function of the external obliques?

Back

The external obliques assist in trunk rotation and lateral flexion, as well as providing stability to the core.
