Effects of a Lateral tentorial herniation (temporal lobe herniates through the tentorial notch occupying the midbrain) Depressed Level of Consciousness due to interrupation of the reticular activating formation governing consciousness Compression of the 3rd nerve nucleus in the midbrain leading to 3rd nerve palsy
Its anterior border is free and concave, and bounds a large oval opening, the tentorial incisure, for the transmission of the cerebral peduncles. An uncal herniation refers to the herniation of the uncus downward through the tentorial notch. The displaced uncus typically puts pressure on the midbrain and the oculomotor nerve (CN III). A central herniation involves the displacement of the diencephalon and cortical structures through the tentorial notch. Central herniations are typically This page is based on the copyrighted Wikipedia article "Tentorial_notch" ; it is used under the Creative Commons Attribution-ShareAlike 3.0 Unported License.

tentorial notch An arched cavity in the free border of the tentorium cerebelli through which the brainstem passes. The anterior portion contains the tentorial notch (or tentorial incisure/incisura) which is a U-shaped (concave) free edge and extends anteriorly to attach to the anterior clinoid processes 1 and forms the lateral part of the cavernous sinus 3. Video shows what tentorial notch means. The space in the tentorium where the brainstem passes.. Tentorial notch Meaning. How to pronounce, definition audio The tentorial incisura is located between the tentorial edges and is the only site of communication behind the supra and infratentorial spaces. The tentorial apex is located at the junction of the vein of Galen and the straight sinus.

The tentorial notch (also known as the tentorial incisure or incisura tentorii) refers to the anterior opening between the free edge of the cerebellar tentorium and the clivus for the passage of the brainstem. wikipedia The tentorial incisura is located between the tentorial edges and is the only site of communication behind the supra and infratentorial spaces. The tentorial apex is located at the junction of the vein of Galen and the straight sinus. The tentorial edges slope downward from the apex. The tentorial notch allows for the presence of a gap, which lodges the midbrain [1,6].
ten·to·ri·al notch. [TA] the triangular opening in the tentorium cerebelli through which the brainstem extends from the posterior into the middle cranial fossa.
The midbrain inhabits the anterior portion of the incisura and the posterior half is occupied by the superior vermis or the splenium of the corpus collosum.

OBJECT Variations in the structure of the tentorial notch may influence the degree of brainstem distortion in transtentorial herniation, concussion, and acceleration-deceleration injuries. The authors examined the anatomical relationships of the mesencephalon, cerebellum, and oculomotor nerves to the dimensions of the tentorial aperture. On the basis of numerical data collected from this study
Ossification of the tentorium cerebelli over the trigeminal notch is rare, but it may cause compression of the trigeminal nerve, leading to trigeminal neuralgia (TN).

The tentorial nerve is the first branch of the ophthalmic division of the trigeminal nerve (CN Va) which is the dominate dural nerve supplying most of the supratentorial dura. It specifically supplies the falx, calvarial dura and superior surface tentorial notch (plural tentorial notches) (biology) The space in the tentorium where the brainstem passes. Anatomical terms of neuroanatomy. The tentorial notch (also known as the tentorial incisure or incisura tentorii) refers to the anterior opening between the free edge of the cerebellar tentorium and the clivus for the passage of the brainstem.   The tentorial notch allows for the presence of a gap, which lodges the midbrain . The midbrain inhabits the anterior portion of the incisura and the posterior half is occupied by the superior vermis or the splenium of the corpus collosum.
The tentorial notch refers to the anterior opening between the free edge of the tentorium cerebelli and theclivus for the passage of the brainstem. It's located between the tentorial edges and communicates the supratentorial and infratentorial spaces.

Together, these findings suggest that the tentorial angle can serve as an imaging biomarker of posterior fossa development during the second half of fetal life. The tentorial apex is located at the junction of the vein of Galen and the straight sinus. The tentorial edges slope downward from the apex. The free edge passes along the side of the brainstem and anteriorly blends into the dura covering the petrous apex and the anterior and posterior clinoid processes. Diplopia may occur due to cranial nerve palsies - the 6th cranial nerve is particularly vulnerable to stretch while the 3rd cranial nerve is at risk because herniation of the medial temporal lobe through the tentorial notch stretches the nerve as it exits the midbrain. The blood supply to the tentorial notch often comes from the cerebellar marginal artery originating from the meningohypophyseal trunk or directly from the cavernous segment of the ICA, which elongates superiorly on the roof of the cavernous sinus and posteriorly along the margin of the cerebellar tentorium to the straight sinus, supplying the CN III and IV, the wall of the cavernous sinus, inner 1/3 part of the cerebellum, and part of the falx related to the straight sinus .
