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.
1009–1032 of 1303
- RotatoresThe rotatores are the deepest small back muscles, each running from a transverse process to the lamina of the vertebra just above.
- Rubrospinal tractTractus rubrospinalisA crossed descending motor pathway from the red nucleus of the midbrain to the cervical spinal cord, running beside the lateral corticospinal tract.
- 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.
- Saphenous nerveNervus saphenusThe longest sensory branch of the femoral nerve, running through the adductor canal and down the inner leg to the medial foot.
- Sartorius muscleMusculus sartoriusSartorius is the long, narrow, ribbon-like muscle that runs obliquely across the front of the thigh from hip to inner knee.
- Scalenus anterior muscleMusculus scalenus anteriorScalenus anterior is a deep neck muscle running from the transverse processes of C3 to C6 down to the scalene tubercle of the first rib.
- Scalenus medius muscleMusculus scalenus mediusScalenus medius is the biggest and longest scalene muscle, running down the side of the neck from the cervical vertebrae to the first rib.
- Scalenus posterior muscleMusculus scalenus posteriorScalenus posterior, the least and deepest of the scalene muscles, runs from the lower cervical vertebrae to the second rib.
- Scaphocapitate ligamentLigamentum scaphocapitatumA short palmar ligament crossing the midcarpal joint from the distal part of the scaphoid to the capitate.
- Scaphoid boneOs scaphoideumThe boat-shaped carpal bone at the radial edge of the wrist, the largest of the proximal row and the one most often broken.
- Scapholunate interosseous ligamentLigamentum scapholunatum interosseumThe C-shaped intrinsic ligament that joins the scaphoid to the lunate and is the key stabiliser of the proximal carpal row.
- Scaphotrapeziotrapezoidal ligamentLigamentum scaphotrapeziotrapezoideumThe ligament joining the distal pole of the scaphoid to the trapezium and trapezoid on the radial side of the wrist.
- ScapulaThe scapula is the flat, triangular shoulder blade that lies on the upper back and carries the socket of the shoulder joint.
- Scapular spinal part of deltoid musclePars spinalis scapularis musculi deltoideiThe spinal part of the deltoid is its posterior portion, arising from the scapular spine and drawing the arm backward.
- Sciatic nerveNervus ischiadicusThe thickest nerve in the body, leaving the pelvis below piriformis and running down the back of the thigh to divide above the knee.
- ScleraThe tough, opaque white outer coat covering the back five-sixths of the eyeball, continuous with the cornea in front and the optic nerve sheath behind.
- Second posterior intercostal arteryArteria intercostalis posterior secundaThe artery of the second intercostal space, the lower of the two vessels supplied by the supreme intercostal artery.
- Segmental arteries of the lungsArteriae segmentales pulmonumThe branches of the pulmonary arteries that each enter one bronchopulmonary segment alongside its bronchus, carrying blood to be oxygenated.
- Segmental bronchiBronchi segmentalesThe tertiary airways of the lungs, each arising from a lobar bronchus to supply one bronchopulmonary segment, numbered BI to BX on each side.
- Segmental pulmonary veinsVenae segmentales pulmonumThe veins that collect oxygenated blood from the bronchopulmonary segments and join to form the pulmonary veins of each lung.
- 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.
