Anatomy Atlas
Explore the human body structure by structure. The MedicalVideos Anatomy Atlas covers 258 organs, bones, joints, nerves and body systems — each with an illustration, an overview of its structure and function, key facts, and a plain-language look at what can go wrong. Many illustrations are the classic plates from Gray's Anatomy (1918), in the public domain. Every entry links onward to related conditions, procedures, symptoms and muscles, and to videos from the MedicalVideos library, so you can move from structure to clinical relevance in one click.
Skull & Face
The bones of the skull and face, the jaw, the ear ossicles and the teeth — what each one is, how it is built, and what can go wrong with it.
Spine & Back
The vertebral column from the atlas to the coccyx: vertebrae, discs, the spinal canal and the joints that let the back move and bear weight.
Chest & Thorax
The bony cage of the chest and the spaces inside it — the ribs, sternum and the compartments that hold the heart and lungs.
Arm & Hand
The bones and joints of the shoulder, arm, wrist and hand, from the collarbone to the fingertips.
Leg & Foot
The pelvis, leg and foot: the bones and joints that carry your weight, from the hip socket to the toes.
Brain, Senses & Nerves
The brain and spinal cord, the lobes and deep structures, the eye and ear, and the great nerves that connect the brain to the body.

Heart & Circulation
The heart, its chambers, valves, muscle and pacemaker, and the arteries, veins and capillaries that move blood around the body.
See all 19 in Heart & Circulation →
Lungs & Airways
The airways from the nose to the air sacs: how air is warmed, filtered and delivered to the lungs for gas exchange.
See all 14 in Lungs & Airways →
Digestive System
The digestive tract and its glands — mouth, stomach, intestines, liver, gallbladder and pancreas — and how food is broken down and absorbed.
See all 20 in Digestive System →
Urinary System & Kidneys
The kidneys and the drainage pathway — nephrons, ureters, bladder and urethra — that filter the blood and make urine.
See all 8 in Urinary System & Kidneys →
Reproductive System
The male and female reproductive organs: what they are, how they work together, and the problems clinicians commonly assess.
See all 16 in Reproductive System →
Endocrine Glands
The hormone glands — pituitary, thyroid, parathyroids, adrenals, pineal and the pancreatic islets — and the chemical messages they send.
See all 8 in Endocrine Glands →
Lymphatic & Immune System
The drainage and defence network: lymph vessels and nodes, the spleen, thymus, tonsils and bone marrow.
See all 8 in Lymphatic & Immune System →
Skin, Hair & Nails
The skin and its appendages — hair, nails, sweat glands and oil glands — the barrier between you and the world.
Body Systems
The whole-body systems at a glance: skeletal, cardiovascular, nervous, muscular and immune systems, and the joints that connect them.
Frequently asked questions
What is the Anatomy Atlas?
A free educational reference on MedicalVideos.com describing 258 anatomical structures and systems. Each entry explains the structure and function of the part, lists key facts, and summarises the problems that commonly affect it, with links to related conditions, procedures, symptoms and videos.
Where do the illustrations come from?
Most entries are illustrated with plates from Gray's Anatomy (1918), which are in the public domain. Others use stills from MedicalVideos library videos or purpose-made anatomical illustrations; every image carries its credit on the page.
Is this a substitute for medical advice?
No. The atlas is educational information only, reviewed by Dr. Mohamed Ibrahim, Assistant Professor of Medicine (Transplant Nephrology) at the University of Maryland School of Medicine. It does not diagnose or treat any condition — if you have symptoms, see a qualified clinician.
Educational information only. This atlas explains normal anatomy and describes conditions in general terms; it is not medical advice and does not replace assessment by a qualified clinician. If you have symptoms that worry you, seek medical care.
