- Posterior sacro-iliac ligamentLigamentum sacroiliacum posteriusA strong set of fibrous bands behind the sacro-iliac joint, binding the dorsal sacrum to the rear of the ilium.
- Pubic symphysisSymphysis pubicaThe midline cartilaginous joint at the front of the pelvis, uniting the bodies of the right and left pubic bones.
- Renal pelvisPelvis renalisThe funnel-shaped upper end of the ureter, lying partly inside the renal sinus, where the major calyces unite to collect urine.
- Sacrococcygeal symphysisSymphysis sacrococcygeaThe cartilaginous joint between the apex of the sacrum and the base of the coccyx, at the lower end of the vertebral column.
- Sacrospinous ligamentLigamentum sacrospinaleA thin, fan-shaped band in the back wall of the pelvis, stretching from the side of the lower sacrum and coccyx to the ischial spine.
- Sacrotuberous ligamentLigamentum sacrotuberaleA broad, strong band at the back of the pelvis running from the sacrum, coccyx and posterior ilium down to the ischial tuberosity.
- SacrumOs sacrumThe sacrum is the large wedge of fused vertebrae below the lumbar spine, set between the two hip bones at the back of the pelvis.
- Segments of the liverSegmenta hepatisThe eight functional segments of the liver, each with its own branch of portal vein, hepatic artery and bile duct, numbered I to VIII.
- Sigmoid colonColon sigmoideumThe S-shaped loop of colon in the pelvis that links the descending colon to the rectum.
- StomachGasterThe J-shaped, muscular widening of the gut in the upper left abdomen, linking the oesophagus with the duodenum.
- Superior pubic ligamentLigamentum pubicum superiusA thick band across the top of the pubic symphysis, joining the two pubic bones as far out as the pubic tubercles.
- Suprarenal glandGlandula suprarenalisA small endocrine gland capping the upper pole of each kidney in the retroperitoneum, with a steroid-making cortex and an adrenaline-making medulla.
- Taeniae coliThree narrow bands of longitudinal smooth muscle running along the outside of the caecum and colon and meeting at the base of the appendix.
- Transverse colonColon transversumThe longest and most mobile segment of the colon, hanging across the abdomen from the hepatic flexure to the splenic flexure.
- Triradiate cartilageCartilago triradiataThe Y-shaped growth cartilage in a child's hip socket, where the ilium, ischium and pubis meet before they fuse.
- UreterThe narrow muscular tube that carries urine from the renal pelvis of each kidney down the posterior abdominal wall and into the urinary bladder.
- Vermiform appendixAppendix vermiformisA narrow, blind-ended tube opening from the caecum in the right lower abdomen, rich in lymphoid tissue.
