RE-UPLOAD: Rib Movements | Coupled with Thoracic Flexion & Extension

This video tutorial by Kevin Tokoph on Catalyst University explores the movements of the thoracic spine and the associated rib movements. It focuses on thoracic flexion and extension, explaining how the ribs move in response to these spinal movements. The video details the mechanics of rib articulation at the costotransverse joints, highlighting the differences between upper and lower ribs. It also discusses the effects of breathing on thoracic movements, emphasizing the approximation of ribs during flexion and their separation during extension.

What are the two types of joints that ribs use to articulate with the vertebrae?

• Synovial and fibrous joints

• Costovertebral and costotransverse joints

• Hinge and ball-and-socket joints

• Pivot and saddle joints

During thoracic flexion, what is the primary movement of the vertebrae?

• Translation

• Rotation

• Extension

• Flexion

What type of movement do the upper costotransverse joints primarily allow?

• Extension

• Gliding

• Rotation

• Flexion

How do the upper ribs move during thoracic flexion?

• They rotate upwards

• They translate inferiorly

• They translate superiorly

• They rotate downwards

What happens to the space between the ribs during thoracic flexion?

• The space fluctuates

• The space remains the same

• The space decreases

• The space increases

During thoracic extension, what is the primary movement of the vertebrae?

• Translation

• Flexion

• Extension

• Rotation

What type of movement do the lower costotransverse joints primarily allow during extension?

• Extension

• Flexion

• Gliding

• Rotation

How do the lower ribs move during thoracic extension?

• They translate inferiorly

• They rotate downwards

• They translate superiorly

• They rotate upwards

What effect does inhalation have on the thoracic spine?

• Has no effect

• Causes rotation

• Induces slight flexion

• Induces slight extension

What is the typical range of motion for thoracic extension?

• 30 to 35 degrees

• 10 to 15 degrees

• 20 to 25 degrees

• 40 to 45 degrees
