13

MC type of joint?

Synovial (movable)

14

How are synovial joints classified?

By movement
-Hinge
-Pivot
-Condyloid
-Saddle
-Ball and socket
-Plane

15

What type of movement does a hinge joint permit?

Only transverse axis - flexion or extension

16

What type of movement does a pivot joint permit?

Rotation in longitudinal axis

17

What type of movement does a condyloid joint permit?

Movement in 2 axes (oval articular surfaces, long and short diameters)

18

Which type of joint is also called "egg in spoon" joints and why?

Condyloid
-Articular surfaces are oval

19

What type of movement does saddle joint allow?

Movement in 2 axes (articular surfaces are saddle shaped)

20

What types of joints allow biaxial movement?

Condyloid and saddle joints (synovial)

21

What are polyaxial joints?

Motion is possible in many axes
-Ball and socket
-Plane

22

What type of movement does a plane joint allow?

Polyaxial

23

Stability of a joint depends on what?

-Shape of articular surfaces
-Ligaments
-Associated muscles

24

Define valgus deformity

Distal portion of the bone is displaced away from midline
(knock knees)

25

Define varus deformity

Distal portion of bone is displaced toward midline (bow leg)

26

What is the largest tarsal bone?

Calcaneus

27

Define migratory polyarthritis

One joint is affected, disease subsides, then another joint becomes involved

28

Proximal muscle weakness is usually a ____ while distal weakness is usually a ____

Proximal - myopathy
Distal - neuropathy

38

Where is the MC place for Achilles tendon rupture?

1 to 2 inches proximal to its insertion on calcaneus
