Terms Of Movements

Question 1

Bone movements occur at:

Answer 1

Joints

Question 2

Ranges of motion (ROM) are limited by:

Answer 2

Joint bony architecture, ligaments, & muscles crossing that joint

Question 3

Extension of joint

Answer 3

Is to straighten it. Most joints are in relaxed extension. Movements are directed in sagittai plane

Question 4

Hyperextension

Answer 4

Extreme or abnormal extension

Question 5

Dorsiflexion

Answer 5

Pointing toe (foot) to shin | ankle & wrist joints extension

Question 6

Flexion of joint

Answer 6

Bend it or decrease the angle between bone joints. Movements in sagittal plane

Question 7

Plantar flexion

Answer 7

Toe (foot) away from shin | Ankle joint flexion

Question 8

Adduction of joint

Answer 8

Moves bone toward the midline of body. Directed in coronal plane | (fingers/toes —> hand/foot)

Question 9

Abduction of joint

Answer 9

Moves bone away from midline of body. Directed in coronal plane

Question 10

Circumduction

Answer 10

Circular movement @ ball, socket, condylar, & saddle joints - characterized by flexion, abduction, extension, & adduction in sequence

Question 11

Rotation of joint

Answer 11

Turn the moving bone about its axis | toward body is internal/medial | away is external

Question 12

Supination

Answer 12

External rotation of the radiohumeral joint | involves lifting the medial aspect of foot

Question 13

Pronation

Answer 13

Internal rotation of the radiohumeral joint | involves raising the lateral aspect of foot

Question 14

Inversion

Answer 14

Turns sole of foot inward so medial border of foot is elevated (ankle out “rolling the ankle”)

Question 15

Eversion

Answer 15

Turns sole of foot outward so lateral border is elevated (ankle is forced in)
