Study
Learning anatomy and medicine is mostly retrieval practice. Pick a scope, let the atlas highlight or name a structure, and answer; then test the clinical knowledge that hangs off it. Scores stay on your device.
Identify the structure in 3D
Each question highlights one structure in the atlas and offers four names from the same system. Keys 1–4 answer.
Whole body
Any of the 1,736 structures: the full challenge.
Skeleton
Bones and cartilage: the body's load-bearing frame.
Joints & ligaments
Ligaments, joint capsules, discs and membranes that bind the skeleton.
Teeth
The permanent dentition: 32 teeth of the upper and lower jaws.
Muscles
Skeletal muscles, tendons and aponeuroses that move the body.
Heart
Chambers, valves and walls of the heart, with the pericardium.
Arteries
Systemic and pulmonary arteries carrying blood away from the heart.
Veins
Systemic and pulmonary veins returning blood to the heart.
Nervous system
Brain, spinal cord, cranial and spinal nerves, ganglia and meninges.
Sensory organs
Eyes and ears with their internal structures.
Respiratory
Nose, larynx, trachea, bronchial tree and lungs.
Digestive
Mouth, pharynx, oesophagus, stomach, intestines, liver, pancreas.
Reproductive
Male reproductive organs and ducts.
Female reproductive
Uterus, cervix, vagina, uterine (fallopian) tubes, ovaries and their ligaments, the bladder and the breasts: the female body from the NIH Human Reference Atlas, fitted to the reference pelvis and chest.
Locate the structure in 3D
The reverse exercise, and the one exams use: the atlas names a structure and you click it on the body. Great for surface anatomy and for learning where things sit.
By region
Terminology and clinical quizzes
Match a definition to its name. Ten questions per round; pick a bank.
Questions are generated from the site's articles, which are checked against their cited sources but not yet independently clinically reviewed. Articles whose instructions are being re-checked against current guidance are left out until approved.
Viva practice
Short-answer questions of the kind asked in an oral exam, generated from the physiology key facts, conditions and first-aid steps. Think of the answer, then reveal it.
The history covers the sensation of a bulge or dragging, urinary and bowel symptoms, sexual function and how much the prolapse affects daily life; NICE recommends using a validated pelvic floor symptom questionnaire. Examination with a speculum, at rest and while straining and sometimes standing, shows which compartment is affected and how far it descends, and is recorded using a standard staging system such as the Pelvic Organ Prolapse Quantification (POP-Q) system. The strength of the pelvic floor muscles is assessed at the same time. A urine dipstick is done if there are urinary symptoms, and a bladder scan measures the residual volume if emptying seems incomplete. Imaging is not usually needed: ultrasound or MRI is reserved for unusual symptoms, suspected other pelvic disease or, in advanced prolapse, to check the kidneys for back-pressure. A prolapse found by chance in someone without symptoms does not need treatment.
Pelvic organ prolapse ↗girls 8–13, boys 9–14
Sex hormones and puberty ↗0.8 s
The cardiac cycle ↗≈5 L/min
Cardiac output ↗Persistently raised arterial pressure, usually defined as 140/90 mmHg or more in the clinic (135/85 on home readings).
High blood pressure (hypertension) ↗Progressive, largely irreversible airflow obstruction caused by damage to the airways (chronic bronchitis) and destruction of alveoli (emphysema), almost always from smoking.
Chronic obstructive pulmonary disease (COPD) ↗Clinical, from the pattern of attacks; a headache diary helps. Scans are needed only for red-flag features such as a change in pattern, abnormal examination or a thunderclap onset.
Migraine ↗Flashcards
The atlas shows a structure; reveal its name and a one-line description, then move on.
