Trunk (thorax, abdomen, back)
Articular cartilage of thoracic vertebrae (T1–T12)
Cartilagines articulares vertebrarum thoracicarum
- Origin
- Hyaline cartilage on coronal-oriented thoracic articular facets (T1–T12)
- Insertion
- Thoracic zygapophysial joint surfaces
- Function
- Facilitates smooth thoracic rotation while resisting anterior displacement
- Innervation
- Avascular and aneural
- Movement & chain
- Coronal plane gliding during trunk rotation
- Palpation
- Not palpated directly
- Clinical
- Thoracic facet arthrosis, segmental restriction, pseudoangina.
- Segmental innervation
- T1–T12
- In clinical practice
- Thoracic spine rotational mobilization and rib cage expansion techniques
- Region in the model
- Trunk (thorax, abdomen, back)
