What does the tentorium cerebelli attach?

The fixed margins of the tentorium cerebelli are attached to the superior borders of the petrous part of the temporal bone, known as the posterior clinoid process via the anterior and posterior petroclinoid folds (Figure ​ 4) and along the transverse sinuses grooves on the occipital bone posteriorly.

What does the tentorium cerebelli attach?

The fixed margins of the tentorium cerebelli are attached to the superior borders of the petrous part of the temporal bone, known as the posterior clinoid process via the anterior and posterior petroclinoid folds (Figure ​ 4) and along the transverse sinuses grooves on the occipital bone posteriorly.

What does tentorium cerebelli mean in anatomy?

tent of the cerebellum
The tentorium cerebelli (Latin for “tent of the cerebellum”) is an invagination of the meningeal layer of the dura mater that separates the occipital and temporal lobes of the cerebral hemispheres from the cerebellum and brainstem.

What is above the tentorium cerebelli?

The falx cerebri (a vertical fold of dura and the largest of the four dural septa) attaches to the superior surface of the tentorium cerebelli along the midline (the straight sinus is contained within this attachment), and a further vertical fold of dura; the falx cerebelli is attached to its inferior surface along its …

What is supratentorial compartment?

The brain is divided into supratentorial and infratentorial compartments by the tentorium cerebelli. The supratentorial compartment includes the cerebral hemispheres and the sellar, pineal, and diencephalic regions, whereas the infratentorial compartment includes the midbrain, pons, medulla, and cerebellum.

What is the function of the tentorium cerebelli quizlet?

The falx cerebelli separates the two hemispheres of the cerebellum. The tentorium cerebelli separates the cerebrum from the cerebellum.

What brain stem region lies or sits in the tentorial notch Incisura?

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 midbrain continues with the thalamus of the diencephalon through the tentorial notch.

What is the supratentorial?

The supratentorial area (the upper part of the brain) contains the cerebrum, lateral ventricle and third ventricle (with cerebrospinal fluid shown in blue), choroid plexus, pineal gland, hypothalamus, pituitary gland, and optic nerve.

What is the function of the falx cerebri and the tentorium cerebelli?

The falx cerebri and tentorium cerebelli are dural structures found in the brain. Due to the roles both structures play in constraining brain motion, the falx and tentorium must be identified and included in finite element models of the head to accurately predict brain dynamics during injury events.

Where does tentorium cerebelli attach?

The tentorium cerebelli is attached to the falx cerebri at its midline, and this attachment contains the straight sinus. This attachment is more superior than its anterolateral and posterolateral attachments giving it a “tented” appearance 1.
