Birth Defects
Overview Birth defects are the leading cause of perinatal and post- neonatal deaths, and result in substantial morbidity and disability in developed countries. There is a wide variety of mechanisms including genetic, environmental and multifactorial. Major birth defects affect 2–3% of live-borns, and minor birth defects affect 15%. Preventative strategies remain limited, but include maternal folic acid supplementation,…

Cervical Cancer
Overview Cervical cancer is an HPV-related malignancy of the uterine cervical mucosa. Most cervical tumours contain HPV DNA (99.7%) . There are many variants of HPV, HPV-16 and 18 are the 2 most common high-risk types. Cervical cancer is proceeded by an idenifiable precursor lesion (cervical intraepithelial neoplasia (CIN1)) that may progress to invasive cancer. CIN can…

Spondylarthropathy
Overview The spondyloarthropathies are a diverse group of inflammatory arthritides that share certain genetic predisposing factors and clinical features. Their most characteristic feature is inflammatory back pain. Enthesitis, another characteristic feature, involves inflammation at sites where tendons, ligaments, or joint capsules attach to bone. Features of Spondylarthropathy Sacroiliac and spinal (axial involvement) Enthesitis at long attachments…

Croup
Overview Croup, also known as largnotracheobronchitis, is a usually self limiting upper airway viral infection causing upper airway obstruction. Croup is more common in boys than in girls, usually occurs between six and 36 months of age, and peaks during the second year of life. Croup is usually caused by viruses, which are detected in up to…

Sickle Cell Anaemia
Overview Sickle cell anaemia is an autosomal recessive genetic hemoglobinopathy caused by a single point mutation in the beta-globin gene ( HBB ) on chromosome 11. This mutation results in a substitution of valine for glutamic acid at the sixth position of the beta-globin chain, producing abnormal hemoglobin S (HbS). Under deoxygenated or stressful physiological…

Cervical Stinger/Burner Injuries
Overview A cervical stinger or burner is a transient peripheral nerve injury caused by traction, compression or direct trauma to a cervical nerve root or the upper brachial plexus. It typically occurs during collision or contact sport and produces sudden unilateral burning, stinging or electric-shock pain radiating from the neck or shoulder into the arm.…

Good places to begin
Explanations learners return to.
Cardiac output – determinants and calculation (Cardiology)
Learn what cardiac output is and how it reflects the heart’s efficiency in pumping blood throughout the body. This video explains the factors that influence cardiac output—heart rate and stroke volume—and how they are regulated in various physiological conditions.
Cell membrane IV – Saturated, Unsaturated and Cholesterol
Learn how saturated fats, unsaturated fats, and cholesterol affect the structure and fluidity of the cell membrane in this video. Essential for cell biology and exam prep, this video explains lipid interactions, membrane dynamics, and their physiological significance with clear visuals.
The Four Types of Tissues – Epithelial, Connective, Nervous and Muscular
Learn about the four basic types of tissues in the human body: epithelial, connective, nervous, and muscular. This video explains their structures, functions, and how they work together to support overall body function and health.
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.

Student, Neelain University
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.
Scaphoid Fractures: Anatomy, Diagnosis, and Complications
An illustrated review of scaphoid anatomy, fracture mechanisms, clinical findings, imaging, and treatment. Emphasizes missed fractures, the risk of non-union and avascular necrosis from the scaphoid’s retrograde blood supply, and the role of immobilization and MRI or CT when initial X-rays are negative.
