1. Define the following term:
Carrying angle: Angle formed by the longitudinal axes of
the humerus and forearm.
2. Enter the letter by the structures in Figures 11-1 through
11-4 next to the correct label for that structure. You can
also write the names of the structures on the figures.

6. For the joints that follow, identify the shape of the joint, the
degrees of freedom, the motions, the plane, and the axis.
7. At each of the joints that follow, identify which surface is
concave and which is convex.
8. For Figures 11-7 through 11-10:
A. In the table below and using your own words,
enter the origins and insertions for the muscles in
Figures 11-7 through 11-10.
B. On the figures, label the origin and insertion of the
muscles listed. Color the origin in red and the
insertion in blue.
C. Join the origin and insertion to show the line of pull.
