Amyloidosis (Overview)
Overview Amyloidosis is a disorder in which misfolded proteins aggregate into insoluble beta-pleated sheet fibrils and deposit extracellularly in tissues, leading to progressive organ dysfunction. It may be systemic or localized . In current practice, the most clinically important systemic forms are AL (light-chain), AA (serum amyloid A), and ATTR (transthyretin; hereditary or wild-type) .…

Explanations learners return to.
Lung Cancer – Overview
Learn about lung cancer, including its major types, risk factors, and how it develops within lung tissue. This video provides an overview of symptoms, diagnostic methods, and general approaches to treatment and management.
Lung Pleura – Clinical Anatomy and Physiology
Explore the clinical anatomy and physiology of the lung pleura, including the roles of the parietal and visceral layers. This video explains pleural function, innervation, and relevance to conditions like pneumothorax and pleural effusion.
Phenylketonuria
Explore Phenylketonuria (PKU), a genetic metabolic disorder that affects the body’s ability to break down phenylalanine, in this easy-to-understand medical video. Learn about its causes, symptoms, diagnosis, and the importance of early dietary management to prevent complications. This video is ideal for students, parents, and healthcare professionals seeking clear information about PKU.
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…
