  28. Articulations

  29. Articulations (Joints) • Articulations – wherever 2 bones meet • Classified by structure • Fibrous (binding connective tissue) • Cartilaginous (binding connective tissue) • Synovial (permit free movement) • Classified by function • Synarthrosis (Immovable) • Amphiarthrosis (slightly movable) • Diarthrosis (synovial joints)

  30. Synathrosis (no movement) • Sutures • Bones of the skull • Gomphosis • Ligament bonds tooth w/in bony socket • Cartilaginous • Connection between 1st rib and sternum

  31. Amphiarthroses (Slightly Movable) • Syndesmosis • Fibrous joint connected by ligament • Ex. Distal articulation between tibia and fibula • Symphysis • Bones joined by disk of fibrocartilage • Ex. Vertebrae, between pubic bones

  32. Diarthrosis (Synovial Movement) • Bound by joint capsule and contains synovial fluid • Types of movement: • Gliding – 2 opposing surfaces slide past one another (carpals, tarsals) • Angular • Rotation • Special Movement

  33. Angular Movements • Angular Motion • Flexion – reduces angle between articulating elements • Extension - increases angle between articulating elements • Adduction – moving towards midline • Abduction – moving away from midline • Circumduction – loop motion

  34. Rotational Movements • Rotational

  35. Special Movements • Inversion- turns sole of foot inward (opp-eversion) • Dorsiflexion- ankle flexion (plantar flexion pointed toe) • Opposition – grasping (thumb/fingers toward hand) • Protraction - move anterior across horizontal plane (opp retraction) • Elevation – move superior (opp depression)

  36. Structural Classification of Synovial Joints • Gliding – flat surfaces slide past one another • Ends of clavicles • Between carpals & tarsals • Between vertebrae • Hinge – angular movement in a single direction • Occipital bone and atlas • Elbow, knee, ankle • Interphalangeal joints • Pivot – permit rotation only • Atlas and axis • Proximal radius and ulna • Ellipsodial – angular motion occurs in 2 planes • Radius w/proximal carpals • Phalanges w/metacarpals (and metatarsals) • Saddle- permits angular motion but prevents rotation • thumb • Ball and socket - round head rests within depression • Shoulder • hips
