Acute Compartment Syndrome
Overview The muscle groups of the human limbs are divided into section or compartments. Acute compartment syndrome (ACS) occurs when increased pressure within a compartment compromises circulation and function of tissues within that area. common sites of ACS is the leg and forearm. Acute compartment syndrome: A critical pressure increase within a confined compartmental space causing…

Ankle Sprain (Lateral Ligament Injury)
Overview A lateral ankle sprain is an injury to one or more ligaments on the lateral side of the ankle, usually caused by excessive inversion with the foot plantarflexed. The anterior talofibular ligament is injured most commonly, followed by the calcaneofibular ligament and, in severe injuries, the posterior talofibular ligament. 1 Most lateral ankle sprains…

Testicular Torsion
Overview Testicular torsion is a urological emergency caused by twisting of the spermatic cord, leading to acute interruption of blood flow to the testis and rapid ischemia. It most commonly occurs in adolescents (peak 12–18 years) but can occur at any age, including neonates. The incidence is approximately 1 in 4,000 males under 25 years. Early…

Anklylosing Spondylitis (AS)
Overview Ankylosing spondylitis (AS) is a chronic, progressive inflammatory arthritis that primarily affects the axial skeleton, especially the sacroiliac joints and spine. It is a subtype of the seronegative spondyloarthropathies and is characterised by inflammatory back pain, morning stiffness, and eventual spinal fusion in severe cases. AS often presents in young adults, typically males, and…

Hyperparathyroidism
This section will mainly focus on Primary Parathyroidism Overview Primary Hyperparathyroidism (PHPT) is generalised disorder calcium, phosphate and bone metabolism due to increased secretion of parathyroid hormone normally leading to hypercalcaemia and hypophosphatemia. PHPT may present with recurrent nephrolithiasis, peptic ulcers, mental and muscle changes and less frequently bone resorption. Frequently, routine blood tests will…

Good places to begin
Explanations learners return to.
Hepatorenal Syndrome – causes, pathophysiology and mechanism
Learn about hepatorenal syndrome, a serious complication of advanced liver disease that leads to progressive kidney dysfunction. This video explains the underlying causes, pathophysiology, and mechanisms involving renal vasoconstriction and impaired perfusion despite structurally normal kidneys.
Nervous System – Resting Membrane Potential
Understand the resting membrane potential and how ion gradients and membrane permeability maintain electrical balance in neurons. This high-yield video is essential for grasping nerve physiology in exams like the USMLE, NCLEX, or NEET.
Obstetrics – Stages of Labour
Learn the three key stages of labor in this detailed obstetrics overview—from cervical dilation to delivery of the placenta. Understand the physiological changes, clinical signs, and key management points at each stage of labor.
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.
Atypical Pneumonia
Overview Atypical pneumonia is a clinical term traditionally used for pneumonia caused by organisms that do not have a cell wall, live intracellularly, or are not detected on routine bacterial culture. Important causes include Mycoplasma pneumoniae , Chlamydia pneumoniae , Legionella species, Chlamydia psittaci and Coxiella burnetii . Respiratory viruses can produce a similar syndrome.…
