Types of body movements
After completing this study unit you will be able to:
- Name the main bones of the human body.
- Identify the two major subdivisions of the skeleton.
- Describe the five main classifications of types of bones, based on bone shape.
- List the main functions of the skeletal system.
Our musculoskeletal system functions to propel our bodies within space and allows us to interact with the world around us. These movements occur at our synovial joints, as a result of muscles acting on our skeleton. Specific terms are given to each movement to help clearly communicate the way in which a joint is moving.
Watch the following video to learn about the various types of movements occurring in the human body.

|Terminology of movements
||Flexion / extension
Lateral (external) rotation / internal (medial) rotation
Abduction / adduction
Pronation / supination
Elevation / depression
Protraction / retraction
Plantarflexion / dorsiflexion
Eversion / inversion
Opposition / reposition
|Movement at the major joints||
Shoulder: Flexion, extension, abduction, adduction, internal rotation, external rotation, circumduction
Elbow: Flexion, extension
Proximal radioulnar joint: Pronation, supination
Wrist: Flexion, extension, adduction, abduction
Hip: Flexion, extension, abduction, adduction, internal rotation, external rotation, circumduction
Knee: Flexion, extension (small degree of internal / external rotation when knee is flexed)
Ankle: Dorsiflexion, plantarflexion
Subtalar joint: Inversion, eversion
Spine: Flexion, extension, rotation, lateral flexion, rotation (greatest at the atlantoaxial joint)
Mandible: Elevation, depression, protraction, retraction
Scapula: Protraction, retraction, elevation, depression, upward rotation, downward rotation
