anulus fibrosus การใช้

ประโยคมือถือ
  • The anulus fibrosus also becomes weaker with age and has an increased risk of tearing.
  • The nucleus pulposus and the fibers of the anulus fibrosus make up the intervertebral disc.
  • There may be splits in the anulus fibrosus, permitting herniation of elements of nucleus pulposus.
  • With degeneration the contents of the disc, the nucleus pulposus and anulus fibrosus, are exposed to altered loads.
  • The condition is likely triggered by changes in the anulus fibrosus, the tough outer ring of the intervertebral disc.
  • Herniations usually occur posterolaterally, where the anulus fibrosus is relatively thin and is not reinforced by the posterior or anterior longitudinal ligament.
  • These loads are instead transferred non-uniformly through the " anulus fibrosus ", which undergoes progressive, structural deterioration.
  • Exploration missions on planetary surfaces may also introduce habitability issues that could induce excessive torsional stress, an established risk factor for herniation of anulus fibrosus.
  • The spinal discs are composed of a tough spongiform ring of cartilage ( " anulus fibrosus " ) with a more malleable center ( " nucleus pulposus " ).
  • There may also be shrinkage of the nucleus pulposus that produces prolapse or folding of the anulus fibrosus with secondary osteophyte formation at the margins of the adjacent vertebral body.
  • When the " anulus fibrosus " tears due to an injury or the aging process, the " nucleus pulposus " can begin to extrude through the tear.
  • In the alternative, the healing of trauma to the outer anulus fibrosus may result in the innervation of the scar tissue and pain impulses from the disc, as these nerves become inflamed by nucleus pulposus material.
  • Spinal disc herniation, more commonly called a " slipped disc ", is the result of a tear in the outer ring ( anulus fibrosus ) of the intervertebral disc, which lets some of the soft gel-like material, the nucleus pulposus, bulge out in a hernia.
  • Herniation of the contents of the disc into the spinal canal often occurs when the anterior side ( stomach side ) of the disc is compressed while sitting or bending forward, and the contents ( nucleus pulposus ) get pressed against the tightly stretched and thinned membrane ( anulus fibrosus ) on the posterior side ( back side ) of the disc.
