Small bones located between the joints of some cranial bones

9

Articulate

Unite or join
Tibia and femur articulate at the knee joint

23

Structure and function of synovial joints

Joints are the weakest part but still provide great great resistance to any forces trying to push the bones out of alignment

24

Joint types

Fibrous- bones have no joint cavity and they are held together by strong connective tissue

Cartilaginous- bones have no joint cavity, held together by ligaments by cartilage (vertebrae)

Synovial- bones have a joint cavity, held together by ligaments and separated by synovial fluid in the joint cavity (skull)

25

Synovial fluid

Secretion that lubricates and nourishes the articulating cartilage and removes waste products - helps to keep moving surfaces apart
Forms a cushion b/w bones

26

Bursa

Small sac containing synovial fluid, located at friction sites b/w bones and tendons

27

Tendons

Inelastic cords of tissue that attach muscle to bone
Joints are further strengthened by muscle tendons that extend across the joint and assist ligament to hold joint closed

28

Ligaments

Defined fibrous bonds that connect articulating bones
Are designed to assist the joint capsule to maintain stability in the joint by restraining excessive movement, but can also control the degree and direction of movement that occurs

29

Synovial joints

Gliding- b/w carpals and tarsals
Hinge- elbow and knee joints
Pivot- neck, proximal end of radius and ulna
Ellipsoid(condyloid)- metacarpals and phalanges
Saddle- b/w carpal and metacarpal of thumb
Ball and socket- shoulder and hip bone

30

Larynx

Air passes over the larynx and down the trachea
