Study Notes
Cerebellum
- Located in the lower part of the brain, above the brain stem
- Divided into two hemispheres: left and right
External Features
- Cerebellum has a wrinkled surface, with grooves and fissures
- Divided into lobes, fissures, and sulci
Parts of Cerebellum
- Vermis: a narrow, worm-like structure connecting the two hemispheres
- Hemispheres: divided into anterior and posterior lobes
Morphological Divisions of Cerebellum
- Anterior lobe: consists of three parts - central, intermediate, and lateral
- Posterior lobe: consists of pyramis, uvula, and tuber
Functional Divisions of Cerebellum
- Spinocerebellum: receives sensory information from the spinal cord
- Pontocerebellum: receives information from the pons
- Cerebrocerebellum: receives information from the cerebral cortex
Connections of Cerebellum
- Receives information from sensory receptors, spinal cord, and brain stem
- Sends information to the thalamus, red nucleus, and other brain structures
Grey Matter of Cerebellum
- Consists of an outer grey layer (cerebellar cortex) and inner white matter
- Grey matter contains Purkinje cells, granule cells, and interneurons
Blood Supply
- Cerebellum receives blood from the vertebral and basilar arteries
Functions of Cerebellum
- Coordinates voluntary movements, balance, and posture
- Regulates muscle tone and maintains equilibrium
- Helps in learning and remembering motor skills
