- Sphenomandibular ligamentLigamentum sphenomandibulareA thin flat band beside the jaw joint, running from the spine of the sphenoid down to the lingula of the mandible.
- Spinal branch of iliolumbar arteryRamus spinalis arteriae iliolumbalisA small branch of the iliolumbar artery that enters the vertebral canal at the lumbosacral junction to supply the cauda equina and its coverings.
- Spinal duraDura spinalisThe tough outer membrane forming a closed tube around the spinal cord and nerve roots, from the foramen magnum to the sacrum.
- Spinal ganglionGanglion spinaleA swelling on the posterior root of each spinal nerve, lying in the intervertebral foramen and holding the cell bodies of the sensory neurons.
- Spinal reticular processProcessus reticularis spinalisA net-like zone of grey matter strands interlaced with white matter, lying lateral to the base of the posterior horn in the spinal cord.
- Spinalis capitis muscleMusculus spinalis capitisSpinalis capitis is a thin, often indistinct strand of the erector spinae that reaches the skull from the upper thoracic and lower cervical spines.
- Spinalis colli muscleMusculus spinalis colliSpinalis colli is an inconstant deep neck muscle running from the lower nuchal ligament and upper spines to the spine of C2.
- Spinalis thoracis muscleMusculus spinalis thoracisSpinalis thoracis is the thin, innermost column of erector spinae in the back, linking lower and upper thoracic spinous processes.
- Spinotectal tractTractus spinotectalisAn ascending pathway in the anterolateral spinal cord that carries pain and touch signals to the superior colliculus of the midbrain.
- SpleenLienThe largest lymphoid organ, lying in the left upper abdomen under the diaphragm behind the stomach, where it filters the blood.
- Splenic arteryArteria splenicaThe largest branch of the coeliac trunk, a winding artery that runs left along the upper border of the pancreas to the spleen.
- Splenic nodesNodi spleniciA small cluster of abdominal lymph nodes at the hilum of the spleen, beside the pancreatic tail and the splenic vessels.
- Splenic veinVena splenicaA large vein running behind the pancreas from the spleen to meet the superior mesenteric vein, where the portal vein begins.
- Splenius capitis muscleMusculus splenius capitisSplenius capitis is a broad strap muscle at the back of the neck that runs from the upper spines to the mastoid and occiput.
- Splenius colli muscleMusculus splenius colliSplenius colli is a strap muscle of the upper back and neck, running from mid-thoracic spines to the upper cervical transverse processes.
- Sternocleidomastoid muscleMusculus sternocleidomastoideusSternocleidomastoid is the prominent strap muscle running diagonally up the side of the neck from the sternum and clavicle to behind the ear.
- 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.
- Sternohyoid muscleMusculus sternohyoideusSternohyoid is a thin infrahyoid strap muscle in the front of the neck, running from the back of the manubrium to the hyoid bone.
- Sternothyroid muscleMusculus sternothyreoideusSternothyroid is a broad infrahyoid strap muscle that runs from the back of the manubrium to the thyroid cartilage of the larynx.
- StomachGasterThe J-shaped, muscular widening of the gut in the upper left abdomen, linking the oesophagus with the duodenum.
