Adduction

Answer 7

Moves a bone towards the midline

Question 8

Rotation

Answer 8

Moves a bone around a central axis perpendicular to the axis

Question 9

Circumduction

Answer 9

Moves a bone so the ends of it describes a circle and the sides of it describe a bone

Question 18

Opposition

Answer 18

Unique to the thumb, allows the tip of the thumb and the fingers to be bought together

Question 19

Reposition

Answer 19

The opposite of opposition

Question 20

Ball and socket joint

Answer 20

Multi axial, allows the widest range of movement, as in the shoulder and hip joint

Question 21

The hinge joint

Answer 21

Uniaxial, limits movement to flexion and extension examples: Knees, elbows, and the middle and distal phalanges of the fingers and toes

Question 22

Pivot joint

Answer 22

Uniaxial, limits movement to rotation in one plane, such as the atlas and axis articulation in the spine

Question 23

Condyloid joint/ ellipsoidal

Answer 23

Biaxial, allows motion in two planes at right angles to each other, as in the wrist joint between the radius and carpal bones

Question 24

Saddle joint

Answer 24

Biaxial, found only in the thumb, allows movement in two planes at right angles to one another and is located at the carpal metacarpal articulation in the thumb

Question 25

Gliding joint

Answer 25

Multiaxial, allows only gliding motion as in the intervertebral joints in the spine
