View topic ↗Crystal Arthropathy
Overview Crystal arthropathies are a diverse group of disorders characterized by deposition of various minerals in joints and soft tissues leading to inflammation. Four main types of crystal arthropathies: Gout : The most common of all the crystal arthropathies, caused by monosodium urate crystal precipitation, and its prevalence appears to be increasing. Pseudogout: caused by calcium…
View topic ↗Iron Deficiency Anaemia
Overview In the clinical setting, iron deficiency is the most common cause of anaemia. Iron Deficiency is lack of iron in the body resulting from inadequate iron intake, increased iron loss and increased iron demand which can lead to anaemia. Iron is an integral part of haemoglobin the oxygen carrying protein. Without iron, oxygen is unable to…

Overview Leukemia is a common malignancy in children and adults that occurs when alterations in normal cell regulatory processes cause uncontrolled proliferation of hematopoietic stem cells in the bone marrow. Leukaemia: Clonal proliferation of hematopoietic stem cells in the bone marrow Acute Leukaemia: Clonal proliferation of hematopoietic stem cells in the bone marrow that develops…

Portal Hypertension Overview Normal portal vein pressure is 5–10mmHg. Portal hypertension develops when the portal pressure is greater than 12mmHg. Mechanism of disease Increased Intrahepatic resistance of blood flow through the liver due to cirrhosis Increased splanchnic blood flow secondary to vasodilation leading to increased portal flow through liver Cirrhosis is the most common…

Takotsubo Cardiomyopathy (Broken heart syndrome) – pathophysiology, diagnosis and treatment
Takotsubo cardiomyopathy also known as stress cardiomyopathy or apical ballooning syndrome is a heart condition often preceded by a stressful event such as a death of someone or a recent traumatic event. The term "takotsubo" is taken from the Japanese name for an octopus trap, which has a shape that is similar to the systolic…
Light reflex
This video explains the light reflex, detailing the neural pathways involved in the direct and consensual pupillary responses to light. Learn how the optic and oculomotor nerves coordinate to regulate pupil constriction and diagnose neurological conditions.
Antibody Somatic (VDJ) Recombination II
Delve into the second part of Antibody Somatic V(D)J Recombination, focusing on mechanisms like junctional diversity, P- and N-nucleotide addition, and allelic exclusion. This educational video highlights how these processes enhance antigen receptor variability—essential knowledge for immunology exams and understanding adaptive immune responses.
Our mission
Medical science is complex. Understanding it should feel possible.
Armando Hasudungan turns difficult medical science into clear visual explanations and connected learning experiences—so learners can see the whole picture, remember what matters and find a clearer way forward.
See it clearly
Turn abstract processes and invisible relationships into something the learner can picture.
Connect the pieces
Build understanding around how concepts fit together—not a pile of isolated facts.
Make it useful
Help learners move from explanation to recall, revision and the next logical step.
What clarity feels like
When the topic stops being a blur.
Learners do not come back because the subject became easy. They come back because the explanation gave them a picture they could work with.
“Armando's teaching style gives me the foundational knowledge.
Jessica Payne-Burnett
Medical Student, Charles Sturt University
“The notes I make during his videos help me retain everything better.
Ayesha RaiStudent, Islamabad Medical and Dental College
“The drawings are amazing and super easy to remember.

Coming soon: the AH study platform
The explanation is only the start.
The free library helps you find a clear explanation. The AH platform is being built to help you connect the resources, follow a clearer path and check what actually stuck.
- Watch in a focused, ad-free study environment.
- Move between connected videos, notes, diagrams and questions.
- Know what belongs next instead of rebuilding the study path yourself.
- Test your understanding while the topic is still fresh.
New and worth a look
Keep building the picture.
Lambert-Eaton Myasthenic Syndrome
Overview Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the presynaptic neuromuscular junction. It causes impaired acetylcholine release, producing the characteristic triad of proximal muscle weakness, reduced reflexes and autonomic dysfunction. LEMS may occur as a paraneoplastic syndrome—most commonly associated with small-cell lung cancer (SCLC)—or as a non-tumour-associated autoimmune disorder. Neuromuscular junction: connection…
