Anatomy maps
19 interactive maps, 502 named structures. Each one traces a structure back to where it starts, and links the questions that test it.
Nervous
- Brachial plexusRoots to terminal branches, with the lesion pattern for every structure.33 structures · 4 questions
- Lumbosacral plexusRoots L1–S4 to the nerves of the groin, thigh, leg and perineum — foot drop, meralgia paraesthetica, Trendelenburg gait.Draft32 structures · 18 questions
- Cranial nervesAll twelve cranial nerves from brainstem origin to skull foramen, major branch and target, with the classic palsies.Draft32 structures · 13 questions
- Spinal cord tractsFollow discriminative touch, pain and voluntary movement from receptor or cortex to target, with the exact crossing point of each tract and the lesions that expose it.Draft21 structures · 6 questions
- Visual pathwayRetina to calcarine cortex, the field defect at every station, and the pupillary light reflex.Draft16 structures · 11 questions
- Autonomic outflowSympathetic T1–L2 and parasympathetic craniosacral pathways from preganglionic nucleus to ganglion, postganglionic fibre, target organ and receptor, with Horner syndrome and the four head ganglia.Draft32 structures · 34 questions
Cardiovascular
- Cardiac conduction systemSA node to ventricular muscle: intrinsic rates, the artery feeding each segment, and the block or arrhythmia that arises at every level.Draft17 structures · 5 questions
- Coronary circulationAortic sinuses to RCA, LAD and circumflex, their branches, the myocardium each supplies, the ECG leads that show it, dominance, nodal supply and venous return.Draft32 structures · 5 questions
- Branches of the aortaAorta segment by segment: arch vessels, thoracic branches, the T12–L4 abdominal branches and the gut territories they feed.Draft32 structures · 13 questions
- Fetal circulationPlacenta to umbilical arteries: the three shunts, the saturation at every step, and what each becomes after birth.Draft16 structures · 9 questions
Digestive & hepatobiliary
- Gut blood supplyCoeliac trunk, SMA and IMA: the three unpaired aortic branches, what each feeds, where they join, and where the gut becomes ischaemic.Draft28 structures · 9 questions
- Biliary tree and portal systemBile ducts from liver segment to ampulla, and the portal vein from its tributaries to the sinusoids, with the four portosystemic anastomoses and what each produces in portal hypertension.Draft21 structures · 11 questions
Endocrine
- Hypothalamic-pituitary axesEvery releasing hormone from hypothalamus to pituitary cell, target gland and end hormone, with the feedback loop that closes back and the lesion that breaks each step.Draft32 structures · 10 questions
- Calcium homeostasisFrom the parathyroid calcium-sensing receptor through PTH, vitamin D activation, FGF23 and calcitonin to bone, kidney and gut, with the biochemical pattern of every hyperparathyroidism.Draft26 structures · 10 questions
