Femoroacetabular Impingement Syndrome
Overview Femoroacetabular impingement syndrome (FAIS) is a motion-related clinical disorder of the hip in which symptoms and clinical signs occur in association with characteristic femoral and/or acetabular morphology. The accepted diagnostic concept is a triad of symptoms, clinical signs and imaging findings ; bone morphology alone does not establish the syndrome. Patients commonly present with…

Wiskott–Aldrich Syndrome
Overview Wiskott–Aldrich syndrome is a rare X-linked recessive primary immunodeficiency caused by mutations in the WAS gene, leading to defective actin cytoskeleton regulation in hematopoietic cells. It presents with the triad of eczema, recurrent infections, and thrombocytopenia with small platelets. Patients are prone to autoimmunity and malignancy. Incidence is ~1 in 100,000 live male births.…

Hyperlipidaemia
Overview Hyperlipidaemia is an umbrella term which encompasses genetic and acquired disorders that raise lipid levels within the blood. Hyperlipidaemia does not independently cause clinical symptoms, rather can lead to other disorders that can manifest in possible life-threatening presentations. Most notably, hyperlipidaemia causes atherosclerosis which may lead to cardiovascular, cerebrovascular, and peripheral vascular disease. 1…

Myasthenia Gravis
Overview Myasthenia Gravis (MG) is a chronic autoimmune neuromuscular disorder where antibodies target acetylcholine receptors (AChR) or MuSK proteins at the post-synaptic membrane, impairing neuromuscular transmission and causing muscle weakness Myasthenia Gravis (MG) is a rare autoimmune disorder marked by fluctuating muscle weakness that worsens with activity and improves with rest, commonly affecting the ocular…

Post‑splenectomy Immunodeficiency
Overview Post‑splenectomy immunodeficiency refers to the increased susceptibility to infection following removal (or functional loss) of the spleen. The spleen plays a critical role in filtering bloodborne pathogens, especially encapsulated bacteria, and in mounting both innate and adaptive immune responses. Loss of splenic function leads to impaired opsonisation, reduced IgM production, and defective clearance of…

Spermatocele
Overview A spermatocele, or spermatic cyst, is a benign fluid-filled cyst arising from the epididymis, usually near the upper pole of the testis. It commonly contains clear or milky fluid with spermatozoa. Most spermatoceles are painless, discovered incidentally and do not require treatment. Epididymis: coiled structure behind the testis that stores and transports sperm. Spermatocele:…

Adult onset Still's Disease
Overview Adult Onset Still’s Disease (AOSD) is a complex multisystemic autoinflammatory disease characterised by recurrent episodes of spiking fever (> 39–40°C), pink–salmon transient skin rash, and the presence of arthralgia or polyarthritis. First described by Eric Bywaters in 1971 it closely resembles systemic onset juvenile idiopathic arthritis (Still’s disease). retrospective observational study in Japan found…

Good places to begin
Explanations learners return to.
Cardiovascular System Physiology – Cardiac Output (stroke volume, heart rate, preload and afterload)
Understand the core principles of cardiac output by exploring the roles of stroke volume, heart rate, preload, afterload, and contractility. This video offers a clear, high-yield breakdown of cardiovascular physiology essential for exams and clinical practice.
Renin-Angiotensin System (Structure, Chymase)
Describes how Angiotensinogen converts to Angiotensin I then II. And looks at what gets cleaved off the structure of these polypeptide chains. It also talks about chymase and how it functions as an converting enzyme.
Cluster Headaches – symptoms, pathophysiology, treatment
Cluster headache attack is an intense and severe strictly unilateral pain around the eye. It is describe as the worst ever headache, using comparisons such as childbirth, fractures and renal stones. The pain ramps up quite quickly once it starts and typically remains for 15–180 min when untreated.
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.

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.
