9.5 Types Of Movements @ Synovial Joints

Question 1

4 types of movement at synovial joints.

Answer 1

Gliding, angular movements, rotation, special movements

Question 2

Gliding

Answer 2

Side to side and back and forth motions.

Ex: nearly flat bone surfaces like intercarpal and the intertarsal

Question 3

Angular movements

Answer 3

Flexion, extension, lateral flexion, hyperextension, abduction, adduction, circumduction

Question 4

Flexion

Answer 4

Decrease in an angle between articulating bones

Question 5

Extension

Answer 5

Increase in an angle between articulating bones

Question 6

Lateral flexion

Answer 6

Movement along the frontal plane and involves intervertebral joints.

Ex: flexion of the thumb or movement of the trunk from left to ride side

Question 7

Hyperextension

Answer 7

Continuation of extension beyond the anatomical position

Question 8

Abduction

Answer 8

Movement of a bone away from the midline

Question 9

Adduction

Answer 9

Movement of a bone toward the midline

Question 10

Circumduction

Answer 10

Movement of the distal end of a body part in a circle

Question 11

Rotation

Answer 11

A bone revolves around its own longitudinal axis

Ex: turning the head from side to side

Question 12

Lateral rotation

Answer 12

Anterior surface of a bone moving away from the midline

Ex: bent arm moving outward away from the body

Pg.267

Question 13

Medial rotation

Answer 13

Anterior of a bone surface is turning toward the midline.

Ex: bent arm turning inward toward the body

Question 14

Special movements

Answer 14

Elevation, depression, protraction, retraction, inversion, eversion, dorsifelxion, plantar flexion, supination, pronation, opposition.

Question 15

Elevation

Answer 15

To lift up

Closing the mouth, shrugging the shoulders

Question 16

Depression

Answer 16

To press down

Opposite movement of elevation. Opening the mouth or returning shrugged shoulders to anatomical position

Question 17

Protraction

Answer 17

To draw forth

Thrusting your mandible outward. Movement of the body part anteriorly in the transverse plane

Question 18

Retraction

Answer 18

To draw back

Movement of a protracted body part back to its anatomical position.

Question 19

Inversion

Answer 19

To turn inward

Bending the foot inward medially

Question 20

Eversion

Answer 20

To turn outward

Turning the entire foot outward
Pg. 267

Question 21

Dorsiflexion

Answer 21

Bending the foot in the direction of dorsum (superior)

Occurs when standing on your heels and drawing toes back

Question 22

Plantar flexion

Answer 22

Bending of the foot at ankle joint in the inferior direction

Standing on your toes

Question 23

Supination

Answer 23

Palm facing outward as in the anatomical position

Question 24

Pronation

Answer 24

Palm is faced downward, opposite of anatomical position

Question 25

Opposition

Answer 25

the thumb crosses over the palm to touch the finger tips.
