shrugging your shoulders is an example of what two movements?
Shrugging your shoulders involves two movements: elevation and protraction.
Shrugging your shoulders involves two movements: elevation and depression. Elevation refers to the movement where the shoulders move upwards towards the ears, while depression involves the movement where the shoulders move downwards away from the ears. Together, these two movements create the action of shrugging your shoulders.
Shrugging your shoulders involves two main movements: elevation and retraction. Let me explain what these movements mean:
1. Elevation: This movement refers to the upward motion of your shoulders towards your ears. When you shrug your shoulders, you contract the upper trapezius muscles, which are located at the back of your neck and upper shoulders. This contraction causes your shoulders to move upward.
2. Retraction: This movement refers to the backward and inward motion of your shoulder blades. When you shrug, you also engage the middle trapezius muscles, which connect your shoulder blades to your spine. The contraction of these muscles pulls your shoulder blades together and slightly backward.
So, when you shrug your shoulders, your shoulder blades retract and move inward, while your shoulders elevate and move upward towards your ears. These two movements work together to create the motion of shoulder shrugging.
