Thoracic Vertebrae (Giraffe-Looking) + Ribs

rib anatomy

-body (shaft) -costal cartilage -costal groove -head -sternal end -tubercle (includes the facet for articulation with the transverse process) -vertebral end (posterior, includes head and neck)

thoracic vertebrae anatomy (what bone and bone feature articulates with each of the 5 pairs of facets listed in the picture)

-superior costal facet: articulates with the head of the rib above it (which is also articulating with the inferior costal facet in Tn-1) -inferior costal facet: articulates with the head of the rib below it (which is also articulating with the superior costal facet in Tn+1) -superior articular facet: articulates with the inferior facet of the thoracic vertebra above it -inferior articular facet: articulates with the superior facet of the thoracic vertebra below it -transverse articular facet: articulates with the tubercle of the rib

Ribs 1-10

They contact their vertebrae at 2 points: costal facet + transverse costal facet

What ribs are false? True? Floating?

true ribs: 1-7 false ribs (indirectly attaching to the sternum): 8-12 floating (no attachment to the sternum): 11-12
