Central Nervous System Anatomy
Localise brain, brainstem, visual pathway and spinal-cord lesions from basic neuroanatomy.
How to prepare for MRCEM Primary
Protect Anatomy and Physiology, which together form two-thirds of the paper, while retaining deliberate coverage of all four smaller categories and their official subcategories.
Core concepts
Concept 1
Cerebral lobes and cortex, internal capsule, basal nuclei, visual pathways, ventricles and CSF, blood supply, brainstem, cerebellum, spinal tracts and cord syndromes.
Exam cue: Name the structure, mechanism, organism, medicine action or evidence measure being tested.
Concept 2
Translate focal signs and visual or long-tract patterns into lesion side, level, vascular territory and likely emergency consequence.
Exam cue: Connect the recalled fact to one clinically relevant emergency-care consequence.
Concept 3
Recognise anatomy of raised intracranial pressure, herniation, obstructed CSF and cord compromise requiring urgent action.
Exam cue: Check units, direction, anatomical level, timing and the exact lead-in before selecting one answer.
Concept 4
Keep revision at the detailed applied basic-science level defined by the RCEM Basic Sciences Curriculum rather than drifting into higher clinical-management knowledge.
Risk pitfalls and guardrails
Localising from one sign without accounting for decussation, combined tract findings and the anatomical level.
Guardrail: Do not localise from one memorised label; combine level, relation, motor, sensory and vascular findings.
Choosing an option that is partly plausible rather than the single option that is fully correct.
Guardrail: Do not select an answer because it is partly true; test it against every word of the lead-in.
Turning a basic-science item into a management question beyond the Primary remembering-and-understanding boundary.
Guardrail: Do not select an answer because it is partly true; test it against every word of the lead-in.
Memory anchors
Central Nervous System Anatomy: scope
Cerebral lobes and cortex, internal capsule, basal nuclei, visual pathways, ventricles and CSF, blood supply, brainstem, cerebellum, spinal tracts and cord syndromes.
Central Nervous System Anatomy: applied link
Translate focal signs and visual or long-tract patterns into lesion side, level, vascular territory and likely emergency consequence.
Central Nervous System Anatomy: safety boundary
Recognise anatomy of raised intracranial pressure, herniation, obstructed CSF and cord compromise requiring urgent action.
Central Nervous System Anatomy: common trap
Localising from one sign without accounting for decussation, combined tract findings and the anatomical level.
Central Nervous System Anatomy: Primary sequence
Recall the underlying structure or mechanism, connect it to the emergency-care finding, exclude the main safety trap, then choose the single fully correct option.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A patient has weakness and sensory loss affecting the right face and arm more than the leg, with expressive dysphasia. Which arterial territory is involved?
An infarct causes contralateral leg weakness and abulia with relative sparing of the face and arm. Which artery is affected?
