Myotonic Dystrophy
Overview Autosomal dominant disease characterised by trinucleotide repeat of CTG. Also known as Dystrophica Myotoncia the disease is causes an increase in muscle tone (Myotonia) with associated degeneration and shrinkage of muscle fibres (Dystrophy). Myotonia: Delayed relaxation of skeletal muscle following voluntary contraction or mechanical stimulation (e.g., persistent grip after a handshake or a persistent…

Osgood Schlatter
Overview In this common disorder of adolescence the tibial tubercle becomes painful and ‘swollen’. Although often called osteochondritis and apophysitis, it is nothing more than a traction injury of the apophysis into which part of the patellar tendon is attached. Osgood-Schaltter disease typically occurs during the early adolescent growth spurt between 10-15 years of age,…

Lumbosacral Radiculopathy
Overview Lumbosacral radiculopathy is dysfunction or irritation of a lumbar or sacral spinal nerve root. It typically causes radiating pain from the lower back or buttock into one leg, sometimes with paraesthesia, sensory loss, weakness or reduced reflexes. The distribution and neurological findings help identify the affected root. The commonest cause is a lumbar disc…

Urinary Incontinence
Overview Urinary incontinence is defined by the International Continence Society as the objective demonstration of involuntary leakage of urine. It is a common and distressing clinical condition that severely impacts physical health, psychological well-being, and overall quality of life. The condition is broadly caused by a disruption in the coordinated lower urinary tract mechanisms responsible…

Baker's Cyst
Overview A Baker’s cyst, also called a popliteal cyst, is a collection of synovial fluid at the back of the knee. It usually develops when excess fluid produced within the knee joint passes into the bursa between the semimembranosus tendon and the medial head of the gastrocnemius muscle. In adults, a Baker’s cyst is commonly…

Bronchiectasis
Overview Bronchiectasis was a common disabling and fatal condition in the pre-antibiotic era and remains more common in medically underserved regions of the world. Irreversible dilatation of airways due to in ammatory destruction of airway walls resulting from persistently infected mucus. Bronchiectasis usually affects medium sized airways Bronchiectasis: Bronchiectasis is the permanent dilation of bronchi…

Good places to begin
Explanations learners return to.
Spleen Anatomy and Physiology
Learn about the spleen's anatomy, blood supply, and role in immune surveillance and red blood cell recycling. This video provides a concise overview of spleen physiology, including its functions in both health and disease.
Acute Pancreatitis – Overview (signs and symptoms, pathophysiology, investigations, treatment)
Explore acute pancreatitis in this concise medical overview covering its signs and symptoms, pathophysiology, diagnostic workup, and treatment strategies. Understand how enzyme activation, inflammation, and complications like necrosis are managed clinically.
MHC class II processing – antigen presentation mechanism
Learn how MHC II molecules present extracellular antigens to helper T cells, playing a key role in activating adaptive immune responses. This video explains the antigen processing steps, including endocytosis, peptide loading in endosomes, and the involvement of the invariant chain and HLA-DM.
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.
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…
