Question 12

Synovial Joint

Answer 12

Question 13

Flexion

Answer 13

Moves away from anatomical postion through sagittal plane

Question 14

Extension

Answer 14

Opposite of flexion returns to anatomical postion

Question 15

Dorsiflextion

Answer 15

Raises the toes superiorly

Question 16

Plantar flexion

Answer 16

Pushes toes inferiorly

Question 17

Abduction

Answer 17

Move away from the longitudinal axis in frontal plane

Question 18

Adduction

Answer 18

Opposite of abduction returns to anatomical position

Question 19

Rotation

Answer 19

Turn around long axis of bone. The head is along the midline so we can rotate the head left or right. The limbs can rotate lateral away from the midline or medial towards the midline

Question 20

Pronation

Answer 20

Medial rotation of forearm

Question 21

Supination

Answer 21

Opposite of pronatation returns to anatomical postition

Elevation

Answer 22

Raise superior

Question 23

Depression

Answer 23

lower inferior, opposite of elevation

Question 24

Pivot Joint

Answer 24

Allows roatation only

Question 25

Hinge Joint

Answer 25

Allows angular motion of flextion/extension

Question 26

Saddle Joint

Answer 26

Surface concave on one axis convex on other enables flexion and abduction

Question 27

Plane Joint

Answer 27

Allows a small amount of sliding

Question 28

Condyloid Joint

Answer 28

Oval Face in a depression allows flextion an abduction

Question 29

Ball & Socket

Answer 29

Flextion, abduction, rotation, and circumduction
