In human anatomy, the artery of Adamkiewicz (also arteria radicularis magna) is the largest anterior segmental medullary artery and the dominant segmental feeding vessel to the thoracic cord, supplying the anterior aspect of the cord (from T8 to the conus medullaris) via the anterior spinal artery. [3]
He is credited with describing the major anterior segmental medullary artery, which is also known as the Artery of Adamkiewicz. [2] In the early 1890s, Adamkiewicz published a series of articles claiming the discovery of a cancer-causing parasite he called Coccidium sarcolytus, as well as the existence of an anti-cancer serum. Further testing ...
In human anatomy, the anterior spinal artery is the artery that supplies the anterior portion of the spinal cord. It arises from branches of the vertebral arteries and courses along the anterior aspect of the spinal cord. It is reinforced by several contributory arteries, especially the artery of Adamkiewicz.
Anterior spinal artery syndrome is the most common form of spinal cord infarction. [1] The anterior spinal cord is at increased risk for infarction because it is supplied by the single anterior spinal artery and has little collateral circulation, unlike the posterior spinal cord which is supplied by two posterior spinal arteries.
Segmental medullary arteries, notably the artery of Adamkiewicz, could be excluded from circulation after blockage of intercostal arteries by the device, which directly branches from descending aorta. [12] Furthermore, during open repair, blood flow within aorta is halted by clamping to facilitate the sewing of interposition graft. [12]
The theory has often been extended to a critical period for second-language acquisition (SLA). David Singleton states that in learning a second language, "younger = better in the long run", but points out that there are many exceptions, noting that five percent of adult bilinguals master a second language even though they begin learning it when they are well into adulthood—long after any ...
Zhuazhou (抓週 – literally, "pick" and "anniversary", meaning "one-year-old catch" ) is a Chinese ritual held at a child's first birthday party, when the child is 1 year, i.e. typically twelve months since birth (although variable reckonings as to what constitutes a year of age for entitlement for zhuazhou exist), old.
