Brain Herniation
Overview Brain herniation is the pathological displacement of brain tissue across rigid intracranial structures, such as the falx cerebri or tentorium cerebelli, or through an opening such as the foramen magnum. It develops when a pressure gradient forces tissue from one intracranial compartment into another. 1 Herniation may compress the brainstem, cranial nerves and cerebral…

Acute Heart Failure
Overview Acute Heart Failure (AHF) is a life-threatening medical emergency defined as the rapid onset or sudden worsening of symptoms and signs of heart failure. It results from severe cardiac dysfunction leading to inadequate systemic cardiac output, elevated intracardiac pressures, or both. AHF can present either as de novo heart failure in a patient without…

Aneurysm
Overview An aneurysm is an abnormal localised dilatation of a blood vessel with at least 50% increase in diameter compared to its normal diameter. It is seen more often in arteries compared to veins. Aneurysms are usually asymptomatic until they are very large or they rupture. A ruptured aneurysm can cause massive bleeding and death.…

Tuberculosis
Overview Tuberculosis (TB) is a chronic, communicable infectious disease caused by the acid-fast bacillus Mycobacterium tuberculosis . It primarily affects the pulmonary parenchyma but possesses the capacity to disseminate to virtually any organ system via hematogenous and lymphatic spread. TB remains one of the leading infectious causes of mortality worldwide, representing a major global public…

Approach to bleeding disorders – causes, pathophysiology and investigations
Bleeding disorder can be either due to a problem in primary hemostasis or secondary hemostasis. Primary hemostasis related bleeding disorder are due to problems with platelets – either reduced production, increased consumption or increased destruction. Secondary hemostasis related bleeding disorders are caused by problems with the clotting factors – either a deficiency or presence of…
Middle Ear Anatomy
Explore the detailed anatomy of the middle ear, including the ossicles (malleus, incus, stapes), tympanic membrane, and Eustachian tube. This video breaks down their structure, function in hearing, and clinical relevance in conditions like otitis media.
Cell membrane – structure, components and transport
Discover how the cell membrane (plasma membrane) controls life at the microscopic level — selective permeability, signaling, and transport. This video explains the cell membrane’s structure and function, covering the phospholipid bilayer, cholesterol, integral and peripheral proteins, and glycoproteins that form the glycocalyx. Learn the fluid mosaic model and why membrane composition dictates fluidity, stability,…
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.
Chronic inflammatory demyelinating polyneuropathy (CIDP)
Overview Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder of peripheral nerves and nerve roots, causing demyelination, impaired nerve conduction, weakness, sensory disturbance and reduced or absent reflexes. Typical CIDP causes progressive or relapsing symmetrical proximal and distal weakness with sensory loss developing over at least 8 weeks . This time course helps…
