Which term is used to describe the blockage caused by a traveling clot in blood vessels?

The term that refers to the blockage caused by a traveling clot in blood vessels is "Cerebral Embolism." An embolism occurs when a blood clot or other debris forms away from the site of blockage—typically in the heart or larger arteries—and travels through the bloodstream to lodge in smaller vessels, leading to obstruction.

In the context of the brain, this blockage can disrupt blood flow and result in symptoms such as stroke. Understanding the distinction is crucial because while thrombosis involves a clot that forms at the location of blockage, an embolism describes a clot that migrates from another location. This distinction highlights the nature of the clot's movement and the subsequent impact on blood circulation.

The other terms refer to different conditions: thrombosis specifically involves clot formation at the block site, hemorrhage refers to bleeding due to ruptured blood vessels, and ischemia refers to insufficient blood supply to an area, which can result from either thrombosis or embolism but does not specifically indicate the cause of the blockage.
