gray rami communicantes (medicine) and Sweyn I (sh)


gray rami communicantes (medicine)


gray rami communicantes
Short nerves arising from the lateral aspect of the sympathetic trunk conducting nonmyelinated postsynaptic sympathetic nerve fibres from the sympathetic trunk to the initial portions of all 31 pairs of ventral primary rami of spinal nerves for distribution by all parts (including the dorsal primary ramus) of the spinal nerve. The gray rami are the parietal branches of the sympathetic trunks since all postsynaptic fibres to be distributed to the body wall (including limbs) must pass through them.

Synonym: communicating branches of sympathetic trunk, communicating rami of sympathetic trunk.


Sweyn I (sh)




or Sweyn Forkbeard

died Feb. 3, 1014, Gainsborough, Lincolnshire, Eng.

King of Denmark (งใ 987-1014) and Viking conqueror of Norway and England.

He rebelled against his father, Harald Bluetooth (987), chasing him from Denmark. With Swedish and Norwegian allies, he defeated Olaf I Tryggvason (งใ 1000), becoming virtual ruler of Norway. Sweyn led raids on England in 1003-04 and became king after a successful military campaign in 1013, forcing Ethelred II into exile. Norway reverted to Norwegian rule after Sweyn's death, but the Anglo-Danish empire continued under his son Canute the Great.
