What are the attachments of the tentorium cerebelli?

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.

Where is the left tentorium?

The cerebellar tentorium is an arched lamina, elevated in the middle, and inclining downward toward the circumference. It covers the top of the cerebellum, and supports the occipital lobes of the brain.

What structures are found inferior to the tentorium cerebelli?

There are three paired peduncles. The inferior peduncles ascend from the medulla, the middle enter from the pons, the superior pass from cerebellum to the midbrain.

How does tentorium cerebelli divides the posterior cranial fossa?

Within the closed-brain case, the volume is further divided into three main compartments. The tentorium cerebelli divides the anterior cranial fossa and middle cranial fossa from the posterior cranial fossa, and the falx cerebri divides the supratentorial compartment into left and right subcompartments.

What does falx cerebelli mean?

Medical Definition of falx cerebelli : the smaller of the two folds of dura mater separating the hemispheres of the brain that lies between the lateral lobes of the cerebellum.

What is the difference between falx cerebri and falx cerebelli?

One of these, the falx cerebri, is a sickle-shaped partition lying between the two hemispheres of the brain. Another, the tentorium cerebelli, provides a strong, membranous roof over the cerebellum. A third, the falx cerebelli, projects downward from the tentorium cerebelli between the two cerebellar hemispheres.

What are the 3 dural Septa?

The dura folds to form septa that create the falx cerebri, tentorium cerebelli, falx cerebelli, and diaphragma sellae.

What are the 3 dural septa?

What is the difference between falx cerebelli and tentorium cerebelli?

The falx cerebri (or falx) is a scythe-shaped band of dura matter that separates a part of the cerebral hemispheres. The tentorium cerebelli (or tentorium) separates the cerebrum from the cerebellum and brain stem.

What is the difference between the falx cerebri and falx cerebelli?

Where does the falx cerebri lie?

The falx cerebri is a sickle-shaped fold of dura (Latin: falx, sickle) that lies between the cerebral hemispheres, in the longitudinal fissure.

What is the function of falx cerebelli?

A third, the falx cerebelli, projects downward from the tentorium cerebelli between the two cerebellar hemispheres. The outer portion of the dura mater over the brain serves as a covering, or periosteum, of the inner surfaces of the skull bones.
