Dab tsi yog intervertebral discs thiab lawv txoj haujlwm yog dab tsi?
Cov discs intervertebral yog fibrocartilaginouscushions ua haujlwm raws li tus txha nraub qaum qhov kev poob siab absorbing system, uas tiv thaiv lub vertebrae, hlwb, thiab lwm yam qauv (piv txwv li paj hlwb). Cov discs tso cai rau qee qhov vertebral motion: extension thiab flexion.
