Practical 2 Articulations and body movements

What are Angular Body Movements

movements that change the angle between two bones at a joint

Angular Body Movement: Flexion

Decreases the angle between two bones, usually in the sagittal plane

Angular Body Movement: Extension

Increases the angle between two bones. The reverse of flexion. (Usually straightens a joint)

Angular Body Movement: Abduction

Movement of a limb away from the midline of the body

Angular Body Movement: Adduction

Movement of a limb toward the midline of the body

Angular Body Movement: Circumduction

Movement in which the limb describes a cone, combining flexion, abduction, extension, and adduction (end of your limb moves in a large circle while the joint stays relatively in place)

Special Body Movements: Dorsiflexion

Lifting the foot so the toes point superiorly (EX:standing on your heels and lifting your toes off the ground)

Special Body Movements: Plantar Flexion

Depressing the foot so the toes point inferiorly (downward towards feet) (EX: Standing on your tiptoes or pressing a gas pedal)

Special Body Movements: Inversion

Turning the sole of the foot medially (toward midline) —>You turn the bottom of your foot inward, toward your other foot. (EX: standing and tilt your foot so more of your weight rests on its outer edge, you're performing inversion)

Special Body Movements: Eversion

Turning the sole of the foot laterally—> You turn the bottom of your foot outward, away from your other foot. (EX: Tilting your foot so more of your weight rests on its inner edge.)

Special Body Movements: Protraction

Moving a part anteriorly along the transverse plane, as in jutting out the jaw —→ moving a body part forward.(Anteriorly: means toward the front of your body) (Transverse plane: horizontal plane that divides body into upper and lower portions) (EX: Push your lower jaw forward so your bottom teeth stick out in front of your top teeth)

Special Body Movements: Retraction

Moving a part posteriorly. The reverse of protraction—> You pull a body part backward. (Posteriorly: toward the back of your body) (EX: After sticking your lower jaw forward, pull it back to its original position)

Special Body Movements: Elevation

Lifting a part superiorly—→ raise body part upwards (EX:shrugging the shoulders)

Special Body Movements: Depression

Moving a part inferiorly.—> lowering a body part. The reverse of elevation (EX: After shrugging your shoulders, lower them back down)

Special Body Movements: Opposition

Moving the thumb to touch the tips of the other fingers (EX: This movement is important for gripping and holding objects)
