jugular foramen การใช้

ประโยคมือถือ
  • Also an inferior petrosal sinus enters the sigmoid sinus near the jugular foramen.
  • The sigmoid sinus, which continues the transverse sinus, empties into the jugular vein at the jugular foramen.
  • Causes of damage may include trauma or past surgery, tumours, and causes of compression at the jugular foramen.
  • The glossopharyngeal fibers travel just anterior to the cranial nerves X and XI, which also exit the skull via the jugular foramen.
  • Within the jugular foramen, there are two glossopharyngeal ganglia that contain nerve cell bodies that mediate general, visceral, and special sensation.
  • Upon emerging from the lateral aspect of the medulla, the visceral motor fibers join the other components of CN IX to enter the jugular foramen.
  • Upon emerging from the lateral aspect of the medulla the branchial motor component joins the other components of CN IX to exit the skull via the jugular foramen.
  • Before exiting the jugular foramen, the tympanic nerve enters the petrous portion of the temporal bone and ascends via the inferior tympanic canaliculus to the tympanic cavity.
  • The vagus nerves, from which the recurrent laryngeal nerves branch, exit the skull at the jugular foramen and travel within the carotid sheath alongside the trachea and esophagus.
  • Each sigmoid sinus begins beneath the temporal bone and follows a tortuous course to the jugular foramen, at which point the sinus becomes continuous with the internal jugular vein.
  • Because the cranial part of accessory nerve ( CN XI ) leaves the jugular foramen as joining the CN X, it is sometimes considered part of the plexus as well.
  • These two portions of the inferior border are separated from one another by the jugular process, the notch on the anterior surface of which forms the posterior part of the jugular foramen.
  • These pass along the articulation between the posterior edge of the petrous temporal and the anterior edge of the occipital bones to the jugular foramen where the sigmoid sinus becomes the internal jugular vein.
  • It begins in the postero-inferior part of the cavernous sinus and, passing through the anterior part of the jugular foramen, ends in the superior bulb of the internal jugular vein.
  • The hiatus for lesser petrosal nerve receives the lesser petrosal nerve as it branches from the glossopharyngeal nerve ( CN IX ) before the glossopharyngeal enters the posterior cranial fossa through the jugular foramen.
  • It begins in the postero-inferior part of the cavernous sinus, and, passing through the anterior part of the jugular foramen, ends in the superior bulb of the internal jugular vein.
  • Its lateral half presents an excavation  the jugular fossa  which, with the jugular notch on the occipital, forms the jugular foramen; an eminence occasionally projects from the center of the fossa, and divides the foramen into two.
  • Extending lateralward from the posterior half of the condyle is a quadrilateral plate of bone, the jugular process, excavated in front by the jugular notch, which, in the articulated skull, forms the posterior part of the jugular foramen.
  • It runs lateralward to the jugular foramen, where it may interchange fibers with the spinal portion or even become united to it for a short distance; here it is also connected by one or two filaments with the jugular ganglion of the vagus.
  • It then passes through the jugular foramen, separates from the spinal portion and is continued over the surface of the ganglion nodosum of the vagus, to the surface of which it is adherent, and is distributed principally to the pharyngeal and superior laryngeal branches of the vagus.
