Contribution Analysis of Basic Movements of the Trunk and Spinal Column
Objectives:
 To demonstrate and identify the basic movements of the trunk and spinal
column.
 To identify the muscles associated with each of the basic movements of the trunk
and spinal column and to determine the relative contribution of each of these
muscles to each of the basic movements.
 To identify the origin and insertion of each of the primary agonists of movements
of the trunk and spinal column and to determine the effect of origin and
insertion on the relative contribution of each muscle to each of the basic
movements.
Part 1a: Muscles by Action
Complete the table shown below using your contribution analysis from Part 1b (below).
Under each action, list only the muscles that strongly contribute to that action.
