6. Angular Motion

Question 1

What is Angular Motion?

Answer 1

Angular motion occurs when a body moves along a circular path, revolving around a central line or point

● Angular motion is also referred to as rotation

Question 2

What are the 3 Type of Angular Movements?

Answer 2

Yaw: rotating to the left or right

Pitch: rotating up or down

Roll: tilting to the left or right

Question 4

What is an External Axis of Rotation?

Answer 4

• Imaginary line found outside of the body
• System moves in a circular path around the axis

Question 5

What is an Internal Axis of Rotation?

Answer 5

• Imaginary line found inside of the body
• System moves in a circular path around the axis

Question 6

What are Cardinal Planes?

Answer 6

A plane that passes through the midpoint or center of gravity of the body

Question 7

What is the Saggital Plane?

Answer 7

A vertical plane that divides the body into left & right halfs.

Movements in this plane include flexion and extension

Question 8

What is the Frontal/Coronal Plane?

Answer 8

A vertical plane that divides the body into anterior (front) and posterior (back) sections.

Movements in this plane include abduction and adduction

Question 9

What is the Transverse Plane?

Answer 9

A horizontal plane that divides the body into superior (upper) and inferior (lower) sections.

Movements in this plane include rotation

Question 10

What is Yaw?

Answer 10

Yaw:

• To Rotate around a vertical axis
• Associated with the Transverse (Horizontal) Plane
• Turn left and right - shaking your head “no”

Question 11

What is Pitch?

Answer 11

Pitch:

• rotate around a mediolateral axis
• Associated with the Sagittal Plane
• to look up or down - nodding your head “yes”

Question 12

What is Roll?

Answer 12

Roll:

• Rotate around an anterioposterior axis
• Associated with the Frontal (Coronal) Plane
• Involving side-to-side tilting

Question 13

What axis of movement is associated with the Saggital Plane and what movements are performed in this plane?

Answer 13

Pitch - The Mediolateral Axis

• Flexion / Extension
• Dorsiflexion / Plantarflexion

Question 14

What axis of movement is associated with the Frontal Plane and what movements are performed in this plane?

Answer 14

Roll - The Anteriorposterior Axis

• Abduction / Adduction
• Lateral Flexion
• Elevation / Depression

Question 15

What axis of movement is associated with the Transverse Plane and what movements are performed in this plane?

Answer 15

Yaw - The Longitudal Axis

• Medial / Lateral Rotation
• Pronation / Supination

Question 16

Which of the following motions occurs primarily in the frontal plane?
a) Running
b) Cartwheel
c) Pirouette
d) All of the choices are correct

Answer 16

b) Cartwheel

A cartwheel primarily occurs in the frontal plane as the body moves side-to-side. Running (a) occurs in the sagittal plane, and a pirouette (c) occurs in the transverse plane.
