Blount’s Disease
Overview Blount's disease, also called tibia vara, is a developmental growth disorder of the posteromedial proximal tibial physis. Asymmetric growth produces progressive genu varum centred below the knee, commonly with procurvatum, internal tibial torsion and relative shortening. It differs from physiological bowing because the deformity persists or progresses rather than following normal spontaneous correction.¹,² Early-onset…

Liver Cirrhosis
Overview Cirrhosis is the advanced stage of chronic liver injury characterised by widespread fibrosis, regenerative nodules and distortion of normal hepatic architecture. This causes two major consequences: Portal hypertension Reduced hepatic function Cirrhosis may remain asymptomatic for years before progressing from a compensated to a decompensated stage. Compensated cirrhosis: cirrhosis without major clinical complications. Decompensated…

Pelvic Inflammatory Disease
Overview Pelvic inflammatory disease (PID) comprises a spectrum of inflammatory disorders of the upper female genital tract, including any combination of endometritis, salpingitis, tubo-ovarian abscess, and pelvic peritonitis. Causative organisms are either sexually transmitted (such as C trachomatis , N gonorrhoeae , Mycoplasma genitalium ) or endogenous vaginal organisms (for example, Bacteroides species) that ascend…

Hydatidiform Mole (Molar Pregnancy)
Overview Hydatidiform moles are part of a group of diseases falling under gestational trophoblastic disease. A hydatidiform mole refers to the abnormal growth of trophoblastic cells in the placenta, resulting in edematous placental villi that form hydatidiform structures. It is classified as either partial or complete, causing either abnormal foetal development (resulting in foetal demise)…

Anal Haemorrhoids
Overview Haemorrhoid Plexi are normal anatomical structures located within the anal canal. The term “Anal Haemorrhoids” usually refers to a pathology where the Haemorrhoidal Plexi are enlarged. They are mainly caused by chronic constipation and frequent defecation leading to dilation and engorgement of haemorrhoidal tissue. Common symptoms are bleeding, pain and itching. There are internal…

Schizophrenia
Overview Schizophrenia is a complex syndrome often presenting in late teens/early 20s with positive, negative and cognitive symptoms. Positive symptoms include behaviours and thoughts that are not normally present (psychosis). Negative symptoms include social withdrawal and affective flattening. Finally, cognitive symptoms are expressed as a broad set of cognitive dysfunction. The average lifetime prevalence of…

Anal Abscess
Overview Anorectal abscess is an infection of soft tissue around the anus. It causes severe perianal pain and swelling. 30% to 70% of anorectal abscesses are associated with an anorectal fistula. It is two times more likely to present in males. 1 2 Anal Abscess Anorectal abscess: collection of pus in anorectal spaces resulting from…

Good places to begin
Explanations learners return to.
Physiology of Lipoproteins Cholesterol
Learn the physiology of lipoproteins and cholesterol, including their types, functions, and roles in lipid transport and metabolism. This video breaks down complex pathways like LDL, HDL, and VLDL for clearer understanding and clinical application.
Control Of Respiration (regulation of breathing)
Explore how breathing is regulated by the respiratory centers in the brainstem, responding to changes in carbon dioxide, oxygen, and pH levels. This video explains the roles of central and peripheral chemoreceptors and how they adjust respiratory rate and depth to maintain homeostasis.
Neurology – Physiology Overview
Get a clear, high-yield overview of neurology physiology, covering key concepts like action potentials, neurotransmission, and synaptic integration. Ideal for medical students and anyone preparing for exams like the USMLE or PLAB.
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.
Deep Neck Infection Causes, specific syndromes and symptoms, Complications & Treatment
A structured anatomical and clinical overview of deep neck space infections, detailing fascial anatomy, microbiology, common causative syndromes such as Ludwig angina and peritonsillar abscess, and management principles for medical professionals.
