Can you create a diagram for me central nervous system

Generating Image

A detailed educational diagram of the central nervous system (CNS) showing the brain and spinal cord. The brain should include labeled regions: cerebrum (with frontal, parietal, temporal, and occipital lobes), cerebellum, brainstem (midbrain, pons, medulla oblongata), thalamus, hypothalamus, and corpus callosum. The spinal cord should show cervical, thoracic, lumbar, sacral, and coccygeal segments with labels. Include peripheral nerve connections branching from the spinal cord. Use a clean anatomical illustration style with a light background, color-coded regions, and clear label lines.

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.

A detailed educational pathology classification diagram of CNS (Central Nervous System) Tumors. The diagram is organized as a hierarchical tree/flowchart with the title "CNS Tumors - Pathological Classification" at the top. Branch 1: PRIMARY CNS TUMORS, which splits into: (A) Glial Tumors (Gliomas) - subdivided into: Astrocytoma (Grade I-II, low grade), Glioblastoma Multiforme (Grade IV, most malignant, adults), Oligodendroglioma (Grade II-III), Ependymoma (ventricles/spinal canal); (B) Neuronal Tumors - subdivided into: Medulloblastoma (cerebellum, children, highly malignant), Ganglioglioma; (C) Meningioma - from meninges coverings, mostly benign; (D) Choroid Plexus Tumors - papilloma/carcinoma; (E) CNS Lymphoma - B-cell, immunocompromised. Branch 2: SECONDARY (METASTATIC) TUMORS - most common overall, from lung/breast/melanoma. Include age predilections and key locations as small notes. Color-code by malignancy grade: green for benign/low-grade, orange for intermediate, red for high-grade/malignant. Clean white background, medical textbook style, clear labels and arrows.

CNS Tumors - Pathological Classification

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)?
