Iron Physiology
Explore iron physiology, including its absorption, transport, storage, and role in vital processes like oxygen transport and cellular respiration. This video explains how the body regulates iron levels and the significance of proteins like transferrin, ferritin, and hepcidin.
Baker's Cyst Knee – posterior knee swelling and pain
Baker’s cysts, also known as popliteal cysts, are among the most common knee disorders. These fluid-filled cysts develop at the back of the knee in the popliteal fossa and result from the enlargement of the gastrocnemius-semimembranosus bursa, a bursa located between the gastrocnemius and semimembranosus muscles. Baker’s cysts typically form in adults due to knee…
Neuromuscular Junction
Explore the step-by-step process of neuromuscular transmission, from acetylcholine release to muscle fiber contraction. This high-yield video is perfect for mastering the neuromuscular junction for exams like the USMLE, NCLEX, or PLAB.
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.

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…
