The human body one structure at a time. Every page has a 3D model you can turn, with its parts numbered on it, where it sits, what it does and what supplies it.

- Body of sternumCorpus sterniThe long middle section of the breastbone, between the manubrium and the xiphoid process, carrying the cartilages of the second to seventh ribs.
- Costal cartilagesCartilagines costalesThe bars of hyaline cartilage that carry the ribs forward to the sternum or to each other, giving the front of the chest its spring.
- Costotransverse ligamentLigamentum costotransversariumA short, strong band behind each costotransverse joint, binding the neck of a rib to the transverse process of its own vertebra.
- Cusps of the aortic valveValvulae semilunares valvae aortaeThe three half-moon cusps of the aortic valve, guarding the outlet from the left ventricle into the aorta and named for the coronary arteries.
- Cusps of the pulmonary valveValvulae semilunares valvae trunci pulmonalisThe three semilunar cusps of the pulmonary valve, closing the outlet of the right ventricle into the pulmonary trunk.
- External intercostal membraneMembrana intercostalis externaA thin aponeurotic sheet in the front of each intercostal space, continuing the external intercostal muscle forwards to the sternum.
- First ribCosta primaThe first rib is the shortest, broadest and most curved rib, forming the rim of the upper opening of the thorax.
- Inferior lobe of left lungLobus inferior pulmonis sinistriThe lower of the two lobes of the left lung, behind and below the oblique fissure, resting on the left dome of the diaphragm.
- Inferior lobe of right lungLobus inferior pulmonis dextriThe largest lobe of the right lung, lying behind and below the oblique fissure and resting on the right dome of the diaphragm.
- Intercostal nervesNervi intercostalesThe anterior rami of the first eleven thoracic nerves, each running in an intercostal space to supply the chest and abdominal wall.
- Intermediate bronchusBronchus intermediusThe short stretch of the right main bronchus between the upper-lobe branch and its division into middle and lower lobar bronchi.
- Internal intercostal membraneMembrana intercostalis internaA thin aponeurosis at the back of each intercostal space, carrying the internal intercostal muscle on towards the vertebral column.
- Intra-articular ligament of head of ribLigamentum intraarticulare capitis costaeA short flat band inside the joint of a rib head, tying the crest between its two facets to the intervertebral disc.
- Left inferior lobar bronchusBronchus lobaris inferior sinisterThe lower terminal branch of the left main bronchus, running down and back into the lower lobe of the left lung.
- Left main bronchusBronchus principalis sinisterThe longer, narrower of the two airways formed where the trachea divides, carrying air beneath the aortic arch into the left lung.
- Left superior lobar bronchusBronchus lobaris superior sinisterThe upper of the two branches of the left main bronchus, supplying the upper lobe of the left lung and its lingula.
- Manubrium of sternumManubrium sterniThe wide top section of the breastbone, where the clavicles and the first pair of ribs meet the front of the chest.
- Middle lobar bronchusBronchus lobaris mediusThe forward-running branch of the right intermediate bronchus that supplies the middle lobe of the right lung.
- Middle lobe of right lungLobus medius pulmonis dextriThe smallest lobe of the right lung, a wedge between the horizontal and oblique fissures lying against the front chest wall and heart.
- OesophagusThe muscular tube that carries swallowed food and drink from the pharynx, through the chest and diaphragm, to the stomach.
- Papillary musclesMusculi papillaresCone-shaped muscles projecting from the ventricular walls whose tendinous cords hold the leaflets of the tricuspid and mitral valves.
- PleuraThe thin serous membrane that covers each lung and lines the inside of the chest wall, enclosing a slit-like pleural cavity between.
- Radiate ligament of head of ribLigamentum radiatum capitis costaeA fan-shaped band over the front of each rib-head joint, spreading from the rib head to two vertebral bodies and the disc.
- RibsCostaeThe ribs are the twelve pairs of curved bones that run from the thoracic spine around the chest, forming the rib cage that shields the heart and lungs.
