Systemic Lupus Erythematosus
Overview Systemic Lupus Erythematosus (SLE) is a chronic, multisystem autoimmune disease characterized by the production of autoantibodies and the deposition of immune complexes in various tissues. It predominantly affects women of childbearing age, with a female-to-male ratio of approximately 9:1. The disease is more prevalent among individuals of African, Asian, and Hispanic descent, and its…

Plantar Fasciitis
Overview Plantar fasciitis is a common cause of plantar heel pain associated with repetitive loading of the plantar fascia, the fibrous band that supports the longitudinal arch of the foot. The term plantar fasciopathy is often used because chronic cases show degenerative change rather than prominent inflammation. It typically causes pain beneath the medial heel…

Shingles (Herpes Zoster)
Overview Shingles is reactivation of latent varicella-zoster virus (VZV) following previous chickenpox or, less commonly, varicella vaccination. After primary infection, VZV remains dormant in the dorsal-root or cranial-nerve ganglia. Reactivation occurs when VZV-specific cell-mediated immunity declines. In Australia, incidence is approximately 560 cases per 100,000 people annually and increases markedly after age 50. Lifetime risk…

Viral Encephalitis
Overview Viral encephalitis is an acute, life-threatening inflammatory condition of the brain parenchyma caused by direct viral invasion or secondary immune-mediated mechanisms. It represents a neurological emergency associated with high rates of mortality and long-term neurodevelopmental or cognitive sequelae if treatment is delayed. Infectious encephalitis is distinct from aseptic viral meningitis; while meningitis is confined…

Anal Fissure
Overview Anal fissure is a split in the skin of the distal anal canal. It presents with severe pain on defecation, like passing “glass shards”, and rectal bleeding. It is more frequently diagnosed in younger and middle-aged individuals. Anal fissures are mostly caused by passage of hard stool but can also be a result of…

Genital Prolapse
Overview Genital prolapse, or Pelvic Organ Prolapse (POP), is the symptomatic anatomical descent of one or more pelvic structures—including the anterior vaginal wall, posterior vaginal wall, uterus, or vaginal vault following a hysterectomy. It occurs due to a progressive loss of structural support provided by the pelvic floor muscles, endopelvic fascia, and associated ligamentous attachments.…

Otitis Media
Overview Otitis media is an inflammatory disease of the middle ear cleft, which encompasses the Eustachian tube, tympanic cavity, mastoid antrum, and mastoid air cells. It represents a disease continuum ranging from acute suppurative bacterial infection to sterile fluid effusion and chronic destructive mucosal changes. The underlying pathophysiology is driven by upper respiratory tract infections…

Explanations learners return to.
Lung Function – Lung Volumes and Capacities
Explore the essential lung volumes and capacities that define respiratory function and health in this detailed video. Understand how these measurements aid in diagnosing and managing pulmonary conditions.
Autonomic nervous system overview
Understand the autonomic nervous system as this video breaks down its sympathetic and parasympathetic divisions, key neurotransmitters, and physiological effects. Perfect for grasping how the body maintains homeostasis and responds to stress.
Part II – Oxidative Phosphorylation, Electron Transport Chain
Dive into oxidative phosphorylation and the electron transport chain to understand how cells generate ATP through mitochondrial processes. This video explains the key steps, molecules, and energy conversions involved in the final stage of cellular respiration.
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.
Reem Mohamed Khair Abdalrazig
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.
