Anatomy Basic Common Actions at Anatomical Joints

Innervation

nerve of PNS that carries impulse from CNS to muscle

Joint

Where immovable and moveable bones articulate

Gliding/Translation

Flat surfaces glide or slip over one another

Flexion

Decreases angle between two body parts

Lateral Flexion

Decrease angle between body parts in lateral direction

Extension

Increases the angle between two body parts

Abduction

moving limb away from midline or median plane

Adduction

Moving limb toward the midline or median plane

Circumduction

Moving limb to make cone in space (arm circles)

Rotation

turning of bone around own long axis

Medial rotation or lateral rotation

Turning of bone around its own long axis inwards/outwards

Elevation

Move body part superiorly

Depression

Move body part inferiorly

Protraction

anterior movement in transverse plane

Retraction

Posterior movement in transverse plane

Inversion

Turning the sole of the foot medially

Eversion

Turning the sole of the foot laterally

Dorsiflexion

Bringing the dorsal surface of the foot towards the anterior leg

Plantar flexion

Pushing plantar surface of the foot down

Supination

Rotating forearm laterally which places palm up

Pronation

Rotating forearm medially which places palm down

Opposition

Touching tips of your other fingers on same hand with thumb to grasp things
