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.

- Marginal arteryArteria marginalis coliA continuous arterial channel along the inner border of the colon, linking the colic branches of both mesenteric arteries.
- Medial common iliac nodesNodi iliaci communes medialesCommon iliac lymph nodes lying on the inner side of the common iliac artery, towards the midline below the aortic bifurcation.
- Medial external iliac nodesNodi iliaci externi medialesExternal iliac lymph nodes lying below and inside the external iliac vein on the side wall of the pelvis.
- Median sacral arteryArteria sacralis medianaA slender unpaired artery that leaves the back of the aorta just above its bifurcation and runs down the midline of the sacrum to the coccyx.
- Median sacral nodesNodi sacrales medianiLymph nodes lying in the midline on the front of the sacrum, along the median sacral artery behind the rectum.
- Middle cardiac veinVena media cordis interventricularis inferiorA cardiac vein rising from the apex in the posterior interventricular groove to empty into the right end of the coronary sinus.
- Middle colic arteryArteria colica mediaAn offshoot of the superior mesenteric artery, running in the transverse mesocolon and supplying most of the transverse colon.
- Middle colic nodesNodi colici mediiLymph nodes in the transverse mesocolon set along the middle colic artery, draining most of the transverse colon.
- Middle colic veinVena colica mediaA vein in the transverse mesocolon that drains the transverse colon and runs with the middle colic artery to the superior mesenteric vein.
- Middle lobar artery of right lungArteria lobaris media pulmonis dextriThe branch of the right pulmonary artery that supplies the middle lobe, arising in the fissures of the right lung.
- Musculophrenic arteryArteria musculoohrenicaThe lateral terminal branch of the internal thoracic artery, running along the costal margin behind the lower costal cartilages.
- Musculophrenic veinsVenae musculophrenicaeSmall paired veins running along the inner costal margin with the musculophrenic artery, draining the lower chest wall and diaphragm into the internal thoracic vein.
- Obturator arteryArteria obturatoriaA paired pelvic artery, usually from the internal iliac, that runs along the side wall of the pelvis and leaves it through the obturator canal for the medial thigh.
- Obturator nodesNodi obturatoriiLymph nodes on the side wall of the lesser pelvis beside the obturator artery and nerve, near the obturator canal.
- Paracolic superior mesenteric nodesNodi mesenterici superiores paracoliciSmall superior mesenteric lymph nodes on the inner border of the right and transverse colon, along the marginal artery.
- Pararectal nodesNodi pararectalesLymph nodes lying on the muscular wall of the rectum, within the fatty mesorectum that surrounds it in the back of the pelvis.
- Pectoral branches of thoraco-acromial arteryRami pectorales arteriae thoracoacromialisThe branches of the thoraco-acromial artery that run down between the two pectoral muscles to supply them.
- Pectoralis minor muscleMusculus pectoralis minorPectoralis minor is a thin, triangular chest muscle lying beneath pectoralis major, running from the upper ribs to the coracoid process.
- Posterior branch of renal arteryRamus posterior arteriae renalisThe smaller of the two primary divisions of the renal artery, passing behind the renal pelvis to supply the back of the kidney.
- Posterior division of internal iliac arteryDivisio posterior arteriae iliacae internaecusThe posterior trunk of the internal iliac artery, a short stem giving the iliolumbar, lateral sacral and superior gluteal arteries.
- Posterior intercostal arteriesArteriae intercostales posterioresPaired segmental arteries running in each intercostal space from behind, mostly straight from the thoracic aorta, beneath the lower edge of each rib.
- Posterior leaflet of left atrioventricular valveCuspis posterior valvae atrioventricularis sinistraeThe shorter but wider-based of the two mitral valve leaflets, hanging from the back of the ring between left atrium and ventricle.
- Posterior root of spinal nerveRadix posterior nervi spinalisThe sensory root of each spinal nerve, entering the back of the spinal cord and carrying a ganglion of sensory nerve cells.
- Postvesical nodesNodi postvesicalesSmall lymph nodes lying behind the urinary bladder in the fat around its base, part of the paravesical group.
