Flechsig's tract (medicine) and Yellowstone River (sh)


Flechsig's tract (medicine)


Flechsig's tract -->
posterior spinocerebellar tract


A compact bundle of heavily myelinated, thick fibres at the periphery of the dorsal half of the lateral funiculus of the spinal cord, originating in the ipsilateral thoracic nucleus (column of Clarke) and ascending by way of the inferior cerebellar peduncle. Terminals end as mossy fibres in the granular layer of the cortex of the cerebellar vermis. The bundle conveys largely proprioceptive information originating from the annulospiral nerve endings surrounding muscle spindles and from Golgi tendon organs.

Synonym: tractus spinocerebellaris posterior, Flechsig's tract.


Yellowstone River (sh)




River, northwestern Wyoming and southern and eastern Montana, U.S. The river rises in Wyoming.

It enters Yellowstone National Park and feeds into Yellowstone Lake, below which it plunges 422 feet (129 m) in two spectacular waterfalls and enters the Grand Canyon of the Yellowstone River. It then continues north into Montana. There it flows northeast into the Missouri River on the Montana-North Dakota boundary. It is 692 mi (1,114 km) long and has been developed extensively for irrigation. Its principal tributaries are the Bighorn, Tongue, and Powder rivers. It was first explored in 1806 during the Lewis and Clark Expedition.
