Activity 1

Determine the position of the arms, torso and legs in the following examples.
Use terminology:

anterior or posterior
lateral or medial
superior or inferior.

i.e. Are the arms in example number 1 laterally or medially placed?

Activity 2

Performing dance requires complex actions by each of the joints. Describe the joint actions for each of the following examples. In your answer make reference to the spine, elbows, shoulders, elbows, hips, knees and head.
