bones are bound together by fibrocartilage

A

Symphysis

26
Q

360 degrees range of motion. Heads of humerus and femur

A

Ball and Socket Joint

27
Q

moves in two planes at right angles, effectively 360 degrees range of motion. Proximal head of first metacarpal, sternoclavicular joint

A

Saddle Joint

28
Q

the most common diarthrotic joint, one plane of movement. Phalanges, knee, elbow

A

Hinge Joint

29

30
Q

also called gliding joint, can moves slightly in any direction. Intercarpalar and intertarsalar, intervertebral facets

A

A

Nonaxial Joints

33
Q

allow motion around only one axis - hinge joint, pivot joint

A

Uniaxial Joints

34
Q

allow motion around two axes - saddle joint, condylar joint

A

Biaxial Joints

35
Q

allow motion around three or more axes - ball and socket joint

A

Multiaxial Joints

36

to move a body part towards the sagittal plane

A

Adduction

41
Q

adducting and crossing sagittal plane

A

Hyperadduction

42

Depression

44
Q

extend a part horizontally in a line parallel to the sagittal plane

A

45
Q

tract a part horizontally in a line parallel to the sagittal plane

A

46
Q

moving a part a full 360 degrees

A

Circumduction

52
Q

inflammation of the bursa, usually as the result of calculus formation

A
