Physiology of Cerebellum
The cerebellum is located in the posterior cranial fossa and helps control balance, posture, and skilled voluntary movements. It has three lobes - anterior, posterior, and flocculonodular. The cerebellum contains gray matter in three layers and white matter with afferent and efferent fibers. It is divided into three functional parts - vestibulocerebellum, spinocerebellum, and corticocerebellum. Lesions of the cerebellum cause disturbances in tone, posture, equilibrium, and coordinated movements.

ANATOMY OF CEREBELLUM With Clinical Anatomy.pptx
The cerebellum is located in the posterior cranial fossa behind the pons and medulla. It weighs around 150g and consists of two hemispheres connected by the vermis. The cerebellum coordinates precision and timing of movement rather than initiating movement. It is divided into three lobes - anterior, posterior, and flocculonodular. The cerebellum connects to the brainstem via three peduncles and contains grey matter in a highly folded arrangement. It functions as a comparator, receiving information from the cerebrum and spinal cord to fine tune motor performance. Damage can cause ataxia, nystagmus, gait issues, or intention tremors depending on the affected area.
Cerebellum parts and functions
The cerebellum is located behind the brain stem and contains half of the brain's neurons. It consists of a central vermis and two lateral lobes. The cerebellum is divided into three lobes - anterior, posterior, and flocculonodular. It receives input and sends output via three peduncles. The cerebellum coordinates movement, balance, and posture through feedforward processing in its modular circuitry and plays a role in motor learning. Damage impairs coordination, balance, and movement control.
Anatomy of cerebellum and 4th ventricle
The cerebellum is located in the posterior cranial fossa. It consists of gray matter on the outside forming the cortex, and white matter on the inside. The cerebellum is divided into three lobes - the flocculonodular lobe, anterior lobe, and posterior lobe - by two fissures. It performs important roles in motor control and coordination through connections with other parts of the brain and spinal cord. Lesions of the cerebellum can cause ataxia, tremor, and other movement abnormalities. The fourth ventricle is located between the brainstem and cerebellum.
Cerebellum Physiology
The cerebellum plays an important role in motor control and coordination. It receives input from various sources, including the spinal cord, brainstem, and cerebral cortex. This input is processed within the cerebellar cortex and nuclei. The cerebellum then sends output to motor areas of the brainstem and cerebral cortex to coordinate movement, balance, and posture. It acts as a comparator, receiving feedback on actual movements and comparing them to intended movements, in order to calibrate motor output and prevent overshooting during voluntary motor acts such as walking and running. Damage to the cerebellum can cause ataxia or lack of coordination.

The cerebellum which stands for “little brain”, is a structure of the central nervous system.
It has an important role in motor control.
In particular, it is active in the coordination, precision and timing of movements, as well as in motor learning.
The surface of the cerebellum is marked by a series of small infoldings called folia. It consists of two hemispheres separated by a vermis.
A dural in folding called the tentorium cerebelli separates the superior surface of the cerebellum from the inferior surface of the occipital lobe. Three peduncles connect the cerebellum to other neural structures.
Anatomical Location:
The cerebellum is located at the back of the brain,
immediately inferior to the occipital and temporal lobes.
It is separated from the cerebral lobes by the tentorium cerebelli, a tough layer of dura mater.
It lies at the same level and posterior to the pons, from which it is separated by the fourth ventricle.
The cerebellum consists of grey matter and white matter.Grey matter – located on the
surface of the cerebellum. It is tightly folded, forming the cerebellar cortex.
White matter – located underneath the cerebellar cortex.
parts of Cerebellum :
There are three parts
Anatomical lobes,
zones and
functional divisions
There are three anatomical lobes;
the anterior lobe, the posterior lobe and the flocculonodular lobe.
These lobes are divided by two fissures – the primary fissure and posterolateral fissure.There are two cerebellar zones.
In the midline of the cerebellum is the vermis.
Either side of the vermis is the intermediate zone.
Lateral to the intermediate zone are the lateral hemispheres/lateral zone.The cerebellum has 3 parts:
Archicerebellum (vestibulocerebellum): It includes the flocculonodular lobe, which is located in the medial zone. The archicerebellum helps maintain equilibrium and coordinate eye, head, and neck movements; it is closely interconnected with the vestibular nuclei.
Midline vermis (paleocerebellum)/spinocerebellum: It helps coordinate trunk and leg movements. Vermis lesions result in abnormalities of stance and gait. It is involved in regulating body movements by allowing for error correction. It also receives proprioceptive information.
Lateral hemispheres (neocerebellum)/cerebrocerebellum: They control quick and finely coordinated limb movements, predominantly of the arms and hands.
THE CEREBELLUM IS INVOLVED IN THE FOLLOWING FUNCTIONS:
Maintenance of balance and posture. postural adjustments in order to maintain balance
Coordination of voluntary movements. Most movements are composed of a number of different muscle groups acting together in a temporally coordinated fashion.
Motor learning. The cerebellum is important for motor learning. The cerebellum plays a major role in adapting and fine-tuning motor programs to make accurate movements through a trial-and-error process (e.g., learning to hit a baseball).

Epithelial Tissue.ppt
Cells specialize into four main types of tissues - epithelial, connective, muscle and nervous tissues. Epithelial tissues form protective coverings and linings and have characteristic layers and cell shapes. They perform critical functions like protection, absorption, filtration and secretion. Epithelial tissues are classified based on the number of cell layers and the shape of cells in the layer facing the lumen or open space. Glands are clusters of epithelial and connective tissue cells that secrete products and are either exocrine with ducts or endocrine without ducts.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

Cerebellum Pharm D.pptx
- 4. Cerebellum • The largest part of hind brain and major center of receiving the information from cerebral cortex and from whole body is named as cerebellum. • The major information it receives from body is of Proprioception. • It acts as a guide of cerebral cortex to execute a movement.
- 5. Basic Function of Cerebellum •Three Basic function are there of cerebellum, 1.To Maintain Tone in the muscles 2.Balance and Posture Maintenance 3.Co-ordination of Movement
- 7. Location of its presence •Posterior to Brain Stem. •Inferior to cerebrum and tentorium Cerebelli.
- 9. Connections to Brain Stem • By Bundles of axons or nerve fibers cerebellum is connected to brain stem, these bundles of axons are called as Cerebellar Peduncles. 1. For Connection of Mid Brain with Cerebellum = Superior Cerebellar Peduncles 2. For Connection of Pons with Cerebellum = Middle Cerebellar Peduncles 3. For Connection of Medulla Oblongata with Cerebellum = Inferior Cerebellar Peduncles
- 11. Gross Anatomy of Cerebellum
- 13. Gross Structure of Cerebellum •Grossly cerebellum has two halves called as Cerebellar Hemispheres. •One is Right and One is Left Cerebellar Hemisphere.
- 14. Vermis • Two Halves are joined by a narrow depression in middle. This part is called as Vermis. • Because it looks like a worm
- 16. Surface View Of Cerebellum
- 17. Surface View of Whole Cerebellum • Various Folds are present on the surface of cerebellum. These folds are called as Folia.
- 20. Fissures on the Surface of Cerebellum • Total 3 Fissures are present. • Two main and one less important fissures are present on the surface of cerebellum. • Two main fissures are, 1. Primary Fissure 2. Uvulonodular Fissure or Posterolateral Fissure • Less important one is • Horizontal Fissure
- 23. Anatomical Division of Cerebellum • Two main fissure divide the whole cerebellum into three lobes. 1. Anterior Lobe 2. Middle lobe or Posterior Lobe 3. Flocculonodular Lobe
- 25. Anterior Lobe •That lobe which lies superior to primary fissure is called as Anterior Lobe. •Mainly this lobe is associated with tone in the muscles.
- 28. Posterior or Middle Lobe • That lobe which lies between primary fissure and Uvulonodular fissure is middle lobe or posterior lobe. • This lobe is associated with Coordination of movement and planning of movement .
- 30. Flocculonodular lobe • This is the most primitive or older lobe. • The lobe which lies inferior to Uvulonodular fissure is named as Flocculonodular lobe. • This lobe is associated with Balance and posture maintenance.
- 33. Histological Structure • Microscopically, • The cerebellum has three main parts, 1. Cerebellar Cortex (outer gray matter) 2. White Matter 3. Deep Cerebellar Nuclei
- 34. Cerebellar Cortex • It is gray matter, so it is made up of cell bodies. • Three layers of cell are present in the cerebellar cortex, • My = Molecular Layer (Basket Cells) • Personal = Purkinje Layer (Purkinje Cells) • Gang = Granular Layer (Golgi Cells)
- 36. Deep Cerebellar Nuclei • 4 Deep Cerebellar Nuclei are present in each hemisphere. 1. Dentate Nucleus 2. Emboliform Nucleus 3. Globose Nucleus 4. Fastigial Nucleus
- 39. Thank You
