27. Allow one bone to slide over another. • Move in a back and forth motion • Examples: • Wrist • Ankles Gliding

29. Bones of the core • Skull • Mandible • Ribs • Vertebrae • Pelvis • Scapula • Clavicle

30. Bones of the arms • Humerus • Radius • Ulna • Carpals • Metacarpals • Phalanges

31. Bones of the legs • Femur • Patella • Tarsals • Tibia • Fibula • Metatarsals
