📋 3️⃣ Memory Tables
Table 1: Functional Divisions of Cerebellum
| Division | Main Area | Main Function | Lesion Effect |
|---|---|---|---|
| Vestibulocerebellum | Flocculonodular lobe | Balance and eye movements | Nystagmus, vertigo, imbalance |
| Spinocerebellum | Vermis and intermediate zone | Posture, tone, gait, ongoing correction | Gait ataxia, limb ataxia, hypotonia |
| Cerebrocerebellum | Lateral hemispheres | Planning skilled movements | Dysmetria, intention tremor |
Table 2: Cerebellar Cortex Layers
| Layer | Main Feature | Key Function |
|---|---|---|
| Molecular layer | Pale outer layer | Synaptic integration |
| Purkinje cell layer | Single row of large cells | Final cortical output |
| Granular layer | Dense small cells | Input processing through granule cells |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
• Cerebellum coordinates movement; it does not initiate movement.
• Vermis controls posture, gait, and trunk stability.
• Lateral hemispheres control skilled voluntary limb movements.
• Flocculonodular lobe controls balance and eye movements.
• Purkinje cells are the only output cells of cerebellar cortex.
• Purkinje cells inhibit deep cerebellar nuclei using GABA.
• Mossy fibers act through granule cells and parallel fibers.
• Climbing fibers arise from inferior olivary nucleus.
• Deep nuclei are dentate, emboliform, globose, and fastigial.
• Cerebellar cortex has molecular, Purkinje, and granular layers.
• Cerebellar lesions cause ipsilateral incoordination.
• Main cerebellar signs are ataxia, dysmetria, intention tremor, hypotonia, nystagmus, and scanning speech.
🩺 5️⃣ Clinical Memory Hooks
Clinical Hook:
Vermis lesion → Truncal ataxia and wide-based gait
Clinical Hook:
Lateral hemisphere lesion → Ipsilateral limb ataxia and intention tremor
Clinical Hook:
Flocculonodular lesion → Nystagmus, vertigo, and imbalance
Clinical Hook:
Purkinje cell damage → Loss of inhibitory control over deep nuclei
Clinical Hook:
Cerebellar lesion → Incoordination without primary paralysis
