Can you create a diagram for me central nervous system

Here is your CNS diagram! It covers the key components:
Brain
- Cerebrum - divided into the four lobes (frontal, parietal, temporal, occipital)
- Cerebellum - coordination and balance
- Brainstem - midbrain, pons, and medulla oblongata
- Internal structures - thalamus, hypothalamus, and corpus callosum
Spinal Cord
- All five segments: cervical (C1-C8), thoracic (T1-T12), lumbar (L1-L5), sacral, and coccygeal
- Peripheral nerve branches shown exiting the cord
Let me know if you'd like a more focused diagram of any specific region (e.g., just the brain lobes, brainstem, or spinal cord cross-section), or if you'd like a different style or labeling.

Here is the CNS Tumors classification diagram based on Robbins & Kumar Basic Pathology. Here's a quick summary of what's covered:
Primary CNS Tumors
| Category | Key Tumors | Notes |
|---|---|---|
| Glial (Gliomas) | Astrocytoma, Glioblastoma (GBM), Oligodendroglioma, Ependymoma | GBM = Grade IV, most malignant; adults |
| Neuronal | Medulloblastoma, Ganglioglioma | Medulloblastoma = children, cerebellum |
| Meningioma | Meningioma | Arises from meninges; mostly benign |
| Choroid Plexus | Papilloma / Carcinoma | Rare |
| CNS Lymphoma | Primary B-cell lymphoma | Common in immunocompromised patients |
Secondary (Metastatic) Tumors - the most common CNS tumors overall, from lung, breast, melanoma, etc.
Color coding: Green = benign/low-grade, Orange = intermediate, Red = high-grade/malignant.
Would you like me to drill deeper into any specific tumor type (e.g., GBM histology, medulloblastoma subtypes, or WHO grading)?
