WebThe movements on these joints are called ‘pump-handle’ or ‘bucket-handle’ movements, and are limited to a small degree of gliding and rotation of the rib head. The function of these movements is to enable lifting of … One of the most important functions of ribs and diaphragm is the change in volume of thorax that helps inspiration and expiration. In general, the ribs move around two axes. As the anterior end of ribs is about 4 cm lower than the posterior end, the middle part of rib is lower than anterior and posterior ends. Movement at costovertebral joints 7 to 10 about an anteroposterior axis results in raising and lowering the middle of the rib, the Bucket-handle movement.

Pump Handle vs Bucket Handle Breath Dissociation
WebThe diaphragm contracts and pulls its central tendon down. This increases the negative pressure inside the thoracic cavity, which draws air in. At the same time, the external intercostal muscles raise the anterior chest wall - in a bucket handle action. As the chest cavity becomes larger and wider, the air can enter from outside the body. WebFor expiratory tidal volume, pump-handle movements were 20% smaller than bucket-handle movements.
