Do Now:How do a male and female pelvis

compare?

List 3 joints and describe their movements.

Page 29: The  Appendicular  Skeleton

Articulations: site where 2+ bones meet (joint) providing mobility and stability

Page 30: The  Appendicular  Skeleton

Classification of Articulations Structure (material binding bones)

◦ Fibrous (binding connective tissue)◦ Cartilaginous (binding connective tissue)◦ Synovial (joint capsule)

Function (amount of movement)◦ Synarthrosis (Immovable) -axial◦ Amphiarthrosis (slightly movable)-axial◦ Diarthrosis (freely movable)-appendicular

Page 31: The  Appendicular  Skeleton

Synathrosis (no movement)Sutures (seams) - fibrous

◦Bones of the skullGomphosis

◦Peridontal ligament bonds tooth w/in alveolar margin

Cartilaginous◦Synchondrosis – hyaline cartilage unites

bones Ex. Connection between 1st rib and manubrium

of sternum, epiphyseal plates

Page 32: The  Appendicular  Skeleton

Amphiarthroses (Slightly Movable)

Syndesmosis◦ Fibrous joint connected by

ligament◦ Ex. Distal articulation

between tibia and fibula, interosseous membrane connecting radius and ulna

Symphysis◦ Bones joined by disk of

fibrocartilage◦ Ex. Vertebrae, between pubic

bones

Page 33: The  Appendicular  Skeleton

Diarthrosis (Synovial Movement)

Bound by joint capsule and contains synovial fluid

Structure◦ Articular Cartilage – hyaline◦ Joint Cavity – space w/fluid◦ Articular Capsule – fibrous layer & synovial membrane◦ Synovial Fluid – slippery & viscous lubricant◦ Reinforcing ligaments – strengthen joints◦ Nerves and bv – rich supply◦ Bursae – “ball bearing” or bag of lubricant◦ Tendon sheath – elongated bursae◦ Menisci – between interlocking bones of the knee and jaw

Page 34: The  Appendicular  Skeleton

Stability of JointStabilized to prevent dislocationArticular Surface

◦Shape – ball and socket of hip is most stableLigaments

◦More ligaments increase strength but limit motion

◦Can only stretch 6% of lengthMuscle Tone

◦Tendons are most important stabilizing factor◦Kept taut by muscle tone

Page 35: The  Appendicular  Skeleton

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

Page 36: The  Appendicular  Skeleton

Rotational Movements

Rotational

Page 37: The  Appendicular  Skeleton

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)

Page 38: The  Appendicular  Skeleton

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
