Anatom3DIntervertebral disk of first thoracic vertebra
Discus intervertebralis T I–T II · Meziobratlová ploténka Th1–Th2
Joints & cartilage
Looks like
The pad between T1 and T2: a thin disc, braced at the sides by the rib joints. A tough fibre ring surrounds a soft gel core.
What it does
Joins the two vertebrae, absorbs shock and lets this level bend and twist a little.
Keeping it well
Thoracic disc ruptures are rare because the ribs brace this part; when one presses on the spinal cord it causes leg weakness and needs urgent MRI.
