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
