upper extremity anatomy

Suture joint

gomphosis

Immovable joint

syndesmosis

Where two adjacent bones are linked by strong membrane or ligament

synchondrosis

Slightly movable articulation between bones and hyaline cartilage

symphysis

Two bones have grown closely together limiting movement forming an immovable joint

planar joint

Joints that remain on one plane such as the fingers

hinge joint

pivot joint

condyle joint

saddle joint

ball and socket joint

synarthrotic

Joints that are stuck and immovable. Think of suture joints

amphiarthrotic

Joints that are movable and connected to ligaments or cartilage

diarthrotic

Freely movable joint

nonaxial

Joint where each bone moved the same amount and is very limited, think about avoiding motions, sliding motions. IE wrist bones

diaxial

Joints where two planes of movement are involved. IE condyle joints

multiaxial

Several planes of movement. Ball and socket joint

flexion

Bending a joint by creating tension with the muscle and bone that creates bending.

extension

When there is a relaxation and or muscular action that results in the elongation or relaxation of muscle.

abduction

Movement of muscle or appendage away from the body

adduction

Bringing a muscle or appendage back to the body.

rotation

The act of rotation around an axis

circumduction

Moving in a circular motion

pronation

Inward rolling of the foot

supination

Outward rolling of the foot
