How many different movements are possible at synovial joints?
22 movements
What are the 22 movements possible at synovial joints?
1-2. Flexion/Extension; 3. Lateral flexion at neck or waist; 4-5. ABduction/ADduction; 6. Rotation; 7-8. Medial (Internal) Rotation/Lateral (External) Rotation at the hip or shoulder; 9. Circumduction; 10-11. Inversion (Supination)/Eversion (Pronation) of the foot at the ankle; 12-13. Plantarflexion/Dorsiflexion of the foot at the ankle; 14-15. Protraction (ABduction)/Retraction (ADduction) of the scapula/mandible; 16-17. Elevation/Depression of the scapula/mandible; 18-19. Supination/Pronation of the forearm at the elbow; 20-21. Radial Deviation/Ulnar Deviation of the hand at the wrist; 22. Opposition of the thumb
Movement: Flexion
Occurs when the angle between articulating surfaces is decreased. In the fetal position, the body is in flexion.
Movement: Lateral Flexion
Occurs when the angle between articulating surfaces decreases in a lateral plane. This only occurs at the neck and waist.
Movement: Extension
Occurs when the angle between articulating surfaces is increased. In anatomical position, the body is in extension. Extension may occur when the body returns to anatomic position from a flexed position.Hyperextension is used to describe a joint position which is past anatomic position. The movement is still considered extension but the position is considered hyperextension.
Movement: ABduction
Is the movement of the body part away from the midline.”ABduct away”
Movement: ADduction
Is the movement of the body part towards the midline.”ADd toward”
Movement: Rotation
Is movement of a body part around its own linear axis (imagine putting a string through the length of bone and then rotating the bone around the string).
Movement: Medial (Internal) Rotation
Is when the anterior surface of the body part moves towards the midline. Occurs only at the hip and shoulder.
Movement: Lateral (External) Rotation
Is when the anterior surface of the body part moves away from the midline. Occurs only at the hip and shoulder.
Movement: Circumduction
Occurs when the proximal end of the body part remains stable and the distal end makes a circular movement. Circumduction is the combination of flexion, extension, aBduction and aDduction.
How many special movements of the thigh at the hip and the arm at the shoulder shoulder are there?
2 movements
What are the 2 special movements of the thigh at the hip and the arm at the shoulder?
Medial and Lateral Rotation
How many special movements of the foot at the ankle?
4 movements
What are the 4 special movements of the foot at the ankle?
- Inversion (Supination); 2. Eversion (Pronation); 3. Plantarflexion; and 5. Dorsiflexion
Movement: Inversion (Supination)
Occurs when the sole of the foot faces inward, toward the midline of the body.
Movement: Eversion (Pronation)
Occurs when the sole of the foot faces outward, away from the midline of the body.
Movement: Plantarflexion
Occurs when the foot moves downward, toes pointing away from the head.”Plant your foot on the gas pedal.”
Movement: Dorsiflexion
Occurs when the foot moves upward, toes pointing toward the head.
How many special movements of the scapula and mandible at the TMJ?
4 movements
What are the 4 special movements of the scapula and mandible at the TMJ?
- Protraction (ABduction); 2. Retraction (ADduction); 3. Elevation; and 4. Depression
Movement: Protraction (ABduction)
Occurs when the scapula moves away from the midline of the body or when the mandible is jutted forward away from the body.
Movement: Retraction (ADduction)
Occurs when the scapula moves toward the midline of the body or when the mandible is in anatomical position.
Movement: Elevation
Occurs when the scapula is moved toward the ears or when the mandible is closed.
Movement: Depression
Occurs when the scapula moves downward away from the head or when the mandible is open.
How many special movements of the forearm at the elbow?
2 movements
What are the 2 special movements of the forearm at the elbow?
- Supination; and 2. PronationOnly occurs during flexion.
Movement: Supination
Occurs when the palm is facing upward or anteriorly.
Movement: Pronation
Occurs when the palm is facing downward or posteriorly.
How many special movements of the hand at the wrist?
2 movements
What are the 2 special movements of the hand at the wrist?
- Radial Deviation; and 2. Ulnar Deviation
Movement: Radial Deviation
Hand deviates at the wrist with the thumb leading laterally.
Movement: Ulnar Deviation
Hand deviates at the wrist with the small finger leading medially.
How many special movements of the thumb?
1 movement
What is the special movement of the thumb?
Opposition
Movement: Opposition
Occurs when the thumb moves toward the small finger.
