Module 2 (Joints)

Question 1

How are joints classified

Answer 1

By structure or function
By the type of materials that unite the articulating bones
Based on the extent of movement they permit

Question 2

What are the movements made at synovial joints

Answer 2

Gliding
Angular
Rotation
Special movements

Question 3

Gliding

Answer 3

The motion of bones sliding on one another
ex. wrist

Question 4

Angular

Answer 4

Motion that changes a joint angle

Question 4

Types of angular motion

Answer 4

Flexion
Extension
Abduction
Adduction

Question 5

What is flexion

Answer 5

Decreasing the angle between articulating bones (bending)

Question 6

What is extension

Answer 6

Increasing the angle between articulating bones (straightening)

Question 7

What is abduction

Answer 7

Movement AWAY from the midline of the body

Question 8

What is adduction

Answer 8

Movement TOWARD the midline of the body

Question 9

Rotation

Answer 9

When a joint pivots on its own axis

Question 10

What are the 2 types of rotation

Answer 10

Medial and lateral

Question 11

Medial rotation

Answer 11

TOWARDS the midline

Question 12

Lateral rotation

Answer 12

AWAY from the midline

Question 13

What are the 3 special movements

Answer 13

Pronation and supination
Inversion and eversion
Circumduction

Question 14

What is supination

Answer 14

When the forearm rotates so the palm faces anteriorly (bones are parallel)

Question 15

What is pronation

Answer 15

When the forearm rotates so the palm faces posteriorly (bones cross over each other)

Question 16

What is inversion

Answer 16

When the ankle is twisted so the soles turn medially

Question 17

What is everison

Answer 17

When the ankle is twisted so the soles turn laterally

Question 18

What is circumduction

Answer 18

Continuous movement that combines flexion, abduction, extension, and adduction (arm circles)
