- Splenic veinVena splenicaA large vein running behind the pancreas from the spleen to meet the superior mesenteric vein, where the portal vein begins.
- Sternocostal head of pectoralis major musclePars sternocostalis musculi pectoralis majorisThe sternocostal head is the large lower portion of pectoralis major, spreading from the sternum and upper costal cartilages to the humerus.
- Subaortic nodesNodi subaorticiThe common iliac lymph nodes that lie just below the bifurcation of the abdominal aorta, in front of the lowest lumbar vertebrae.
- Subclavius muscleMusculus subclaviusSubclavius is a small, rounded muscle tucked beneath the clavicle, running from the first rib to the underside of the collarbone.
- Subcostal arteryArteria subcostalisThe lowest paired branch of the thoracic aorta, running beneath the twelfth rib into the back and abdominal wall.
- Subscapular arteryArteria subscapularisThe biggest vessel to leave the axillary artery, running down the lateral border of the scapula to its inferior angle.
- Subscapular veinVena subscapularisA short, wide vein on the posterior wall of the axilla, formed by the circumflex scapular and thoracodorsal veins and draining into the axillary vein.
- Superior anorectal arteryArteria anorectalis superiorThe continuation of the inferior mesenteric artery into the pelvis, the main artery of the rectum and the upper anal canal.
- Superior epigastric arteryArteria epigastrica superiorA terminal branch of the internal thoracic artery that descends inside the rectus sheath to supply the upper anterior abdominal wall.
- Superior epigastric veinsVenae epigastricae superioresPaired veins in the upper rectus sheath that drain the upper anterior abdominal wall and continue upwards as the internal thoracic veins.
- Superior gluteal arteryArteria glutea superiorThe largest internal iliac branch, leaving the pelvis above piriformis to supply the gluteal muscles and hip region.
- Superior gluteal nodesNodi glutei superioresA small group of internal iliac lymph nodes lying along the superior gluteal artery as it leaves the pelvis above piriformis.
- Superior gluteal veinsVenae gluteae superioresPaired companion veins of the superior gluteal artery that drain the upper buttock and enter the pelvis above piriformis to the internal iliac vein.
- Superior lingular artery of left lungArteria lingularis superior pulmonis sinistriThe segmental branch of the left pulmonary artery to the superior lingular segment of the left upper lobe.
- Superior lobar artery of right lungArteria lobaris superior pulmonis dextriThe first branch of the right pulmonary artery, carrying blood to the upper lobe of the right lung.
- Superior mesenteric arteryArteria mesenteries superiorAn unpaired branch of the abdominal aorta that supplies the intestine from the lower duodenum to two-thirds of the way along the transverse colon.
- Superior mesenteric veinVena mesenterica superiorThe large vein draining the small intestine and right colon, which joins the splenic vein behind the pancreas to form the portal vein.
- Superior pancreatic nodesNodi pancreatici superioresA chain of abdominal lymph nodes running along the upper border of the pancreas with the splenic artery, behind the stomach.
- Superior pancreaticoduodenal nodesNodi pancreaticoduodenales superioresThe upper set of lymph nodes in the groove between the head of the pancreas and the duodenum, along the superior pancreaticoduodenal arteries.
- Superior phrenic arteriesArteriae phrenicae superioresSmall paired branches from the lowest part of the thoracic aorta that feed the back of the diaphragm on its thoracic face.
- Superior vena cavaVena cava superiorThe short, wide vein in the right superior mediastinum that returns blood from the upper body to the right atrium.
- Suprascapular arteryArteria suprascapularisAn artery from the thyrocervical trunk that crosses the root of the neck to the back of the scapula, supplying supraspinatus and infraspinatus.
- Suprascapular veinVena suprascapularisA vein of the shoulder and lower neck that drains the back of the scapula and crosses above the clavicle to reach the external jugular vein.
- Supreme intercostal arteryArteria intercostalis supremaA descending branch of the costocervical trunk that crosses the necks of the upper ribs to supply the first two intercostal spaces.
