Cerebellum Anatomy

It is enshrined in posterior cranial fossa behind the pons and medulla oblongata and separated from these structures by cavity of fourth ventricle. The main function of the cerebellum is to organize the complex information received by the brain.

The cerebellum is an integral part of the central nervous system.

Cerebellum anatomy. Like other structures in the central nervous system the cerebellum consists of grey matter and white matter. The cerebellum is located behind the dorsal aspect of the pons and the medulla. The hemispheres of the cerebellum are connected by a central part called the cerebellar vermis.

Similar to the other structures of the central nervous system the cerebellum consists of grey matter and white matter. Like the cerebral cortex the cerebellum is divided into two hemispheres. The anatomy of the cerebellum can be viewed at three levels.

Primary tentorial horizontal petrosal prebiventralprepyramidal suboccipital two hemispheres. Although it only takes up a tenth of the volume of brain tissue it contains as many as half of the whole number of brain neurons. It is connected to brainstem by three fibre tracts known as cerebellar peduncles.

Sagittal section of the human brain showing structures of the cerebellum brainstem and cerebral ventricles. The cerebellum is located in the posterior cranial fossa and lies dorsal to the pons and medulla from which it is separated by the fourth ventricle. The cerebellum is directly connected to the midbrain pons and medulla by the superior middle and inferior cerebellar peduncles respectively Figure 1.

The cerebellum is vital for coordinating movement. The Cerebellum is a central source for the latest developments in fundamental neurosciences including molecular and cellular biology. Anatomists classify the cerebellum as part of the metencephalon which also includes the pons and all its connections with other parts of the brain travel through the pons.

The cerebellum is a portion of the hindbrain located within the posterior cranial fossa of the skull caudal to the cerebrum and tentorium cerebelli and dorsal to the brainstem. The brain is hugely complex but is on a basic level divided into the cerebrum brainstem and cerebellum. Vermis The cerebellar vermis Latin for worm is located in the medial cortico-nuclear zone of the cerebellum residing in the posterior fossa of the cranium.

It is tightly folded forming the cerebellar cortex. At the level of gross anatomy the cerebellum consists of a tightly folded and crumpled layer of cortex with white matter underneath several deep nuclei embedded in the white matter and a fluid-filled ventricle in the middle. It has a large mass from the anterior cerebral cortex and a portion of the brain stem.

Gross Anatomy of the Cerebellum The cerebellum is a large structure with two cerebellar hemispheres4. A midline portion the vermis separates two lateral lobes or cerebellar hemispheres. The vermis runs along the midsagittal plane and separates the hemispheres vertically.

The cerebellum consists of two hemispheres which are connected by the vermis a narrow midline area. Cerebellum controls the same side of body. The primary fissure in the vermis curves ventrolaterally to the superior surface of the cerebellum dividing it into anterior and posterior lobes.

The cerebellum is divided into two hemispheres and a cortex surrounding these hemispheres. Like the cerebral cortex the cerebellum is comprised of white matter and a thin outer layer of densely folded gray matter. Grey matter located on the surface of the cerebellum.

The cerebellum has the following features. Cerebellum is located behind the right brain stem in lower brain area. The cerebellum consists of the cerebellar cortex and the underlying cerebellar white matter Four paired deep cerebellar nuclei are located within the white matter of the cerebellum.

The metencephalon is the upper part of the rhombencephalon or hindbrain. Cerebellar AnatomyThe cerebellum is composed of three lobes Anterior lobe lobules I-V according to the revised Larsell classification. There are 2 major parts to the cerebellum the cerebellar deep nuclei and the cerebellar cortex.

Official publication of the Society for Research on the Cerebellum devoted to genetics of cerebellar ataxias role of cerebellum in motor control and cognitive function and amid an ageing population diseases associated with cerebellar dysfunction. Cerebellum Anatomy The cerebellum is divided into two hemisphereswhich are connected by the vermis a narrow midline area. GROSS ANATOMY OF CEREBELLUMLocationThe term cerebellum is from latin meaning the little brainIt is a part of the hindbrain situated in the posterior cranial fossa.

It is also present behind the pons and medulla ablongataseperated from two structures by the cavity of fourth ventricle. The cerebrum participates. Output from the cerebellum originates solely in the deep nuclei where almost all of the neurons of the cerebellum reside.

Cerebellum is the largest part of the hindbrain and weighs about 150 g. The cerebellum is the area of the hindbrain that controls movement coordination balance equilibrium and muscle tone. It is located in the posterior cranial pit and is covered with a duplicate dura mater which is scientifically called tentorium cerebelli.

Anterior petrosal superior tentorial inferior suboccipital three fissures. Anterior lobe is separated from the posterior lobe by the primary fissure which is easily identified in the axial and midsagittal plane as the deepest and thickest fissure in the superior part of the vermis. Cerebellum section of the brain that coordinates sensory input with muscular responses located just below and behind the cerebral hemispheres and above the medulla oblongata.
