Solution
1.
The inner dural layer is reflected as sheet like protrusions into the cranial cavity. The two main
dural reflections are Tentorium cerebelli and Falx cerebri.
Tentorium cerebelli separates the cerebellum and brainstem from the occipital lobes of the
cerebrum.
Falx cerebri is located in the longitudinal cerebral fissure between two hemispheres.
The two dural infoldings are Diaphragma sellae and Falx cerebelli.
Diaphragma sellae is suspended between the clinoid processes, forming a partial roof over the
hypophysial fossa.
Falx cerebella is a vertical dural infolding that lies inferior to the cerebellar tentorium in the
posterior part of the posterior cranial fossa.
2.
Operation that severs(cuts) the corpus callosum is called as the corpus callosotomy.
Corpus callosum is a band of nerve fibers located deep in the brain that connects the two halves
of the brain. Its function is to pass information from one hemisphere to another.
It is used in the treatment of intractable epilepsy. corpus callosum is cut usually makes the
seizures less severe.
Corpus callosotomy is also called as split brain surgery,is only performed in patients with
extreme and uncontrollable seizure disorders that affect both sides of the brain.
When the corpus callosum is severed, the experimenter can ask each side of the brain the same
question and receive two different answers.
