Bony Joints
Synostosis
example: fusion of two frontal bones into one bone
Fibrous Joints
Suture: frontal and partiel bones
Gomphosis: Teeth and Mandible
Syndesmosis: Distal tibia and distal fibula
Cartilaginous Joints
Synchondrosis: Epiphyseal plate, humeral head and shaft, costal cartilages, first rib and sternum
Symphysis: Joint between two vertebral bodies
Synovial Joints
Plane: between carpalbones
Hinge: Humerus and ulna
Pivot: Atlas and axis
Condyloid: Radius and Scaphoid

shoulder Joint
known as the glenohumeral joint
Glenoid labrum
extra cartilage around the glenoid cavity to deepen the joint
Flexion
a decrease in the joint angle from anatomical position
example: bending your elbow
Extention
returning the flexed body part back to anatomical position
Abduction
movment of the limbs in a coronal plane away from the body
Example: lateral raise
Adduction
return of the body parts away from the coronal plane back to anatomical position
Example: extension portion of a lateral raise
Supination
lateral rotation of the hand
Pronation
Medial rotation of the hand
Protraction
horizontal movement in the anterior direction
example: putting chin forward
Retraction
horizontal movement posterior
example: chin to mouth
Fixing
preventing motion
Inversion
turning feet inward or medial
Eversion
turning soles laterally (away)
