Table 6.2

4. B. Muscle Movements, Types, & Names - Depend on the Mobility of the Specific Joint
Types of Body Movements
Often in pairs for opposite movement
a. *Flexion
b. *Extension
*Opposite of flexion =
Hyperextension

5. Types of Body Movements …
c. *Abduction:
d. *Adduction:

6. e. Rotation
f. Circumduction

7. g. Special Names for Foot Movements
i) Dorsiflexion
= is Flexion
ii) Plantar flexion
= is Extension
Memory Tip: POINT your TOES DOWN to the GROUND where u will PLANT your PLANTS
