Upper Rib Movement EXPLAINED | Bananas and Oranges?

The video tutorial explains the movement of the upper ribs and thoracic spine during flexion and extension. Using two oranges and a banana, the instructor demonstrates how the superior vertebra moves relative to the inferior vertebra, causing upsloping and downsloping. The tutorial also covers how ribs rotate anteriorly or posteriorly depending on the spine's position, with a focus on the upper thoracic spine. The demonstration highlights the importance of understanding these movements for comprehending thoracic spine mechanics.

What happens to the superior vertebra during thoracic flexion?

• It rotates laterally.

• It remains stationary.

• It moves anteriorly and superiorly.

• It moves posteriorly and inferiorly.

In the context of thoracic spine movement, what does 'upsloping' refer to?

• The rib rotating posteriorly.

• The inferior vertebra moving anteriorly.

• The superior vertebra moving posteriorly.

• The superior vertebra moving anteriorly and superiorly.

How can you visualize anterior rotation of the rib?

• By measuring the rib's length.

• By drawing a dot on the superior surface of the rib.

• By drawing a dot on the inferior surface of the rib.

• By observing the rib move laterally.

What is the result of thoracic flexion on rib rotation?

• No rotation and upward movement.

• Lateral rotation and no movement.

• Anterior rotation and downward movement.

• Posterior rotation and upward movement.

During thoracic extension, what happens to the rib?

• It rotates laterally and moves downward.

• It remains stationary.

• It rotates anteriorly and moves downward.

• It rotates posteriorly and moves upward.

What overall rotation occurs to the rib during thoracic flexion?

• Lateral rotation

• No rotation

• Inferior rotation

• Superior rotation

In thoracic extension, what is the overall rotation of the rib?

• Lateral rotation

• Superior rotation

• Inferior rotation

• No rotation
