The surface zone has the ocean's least dense water and represents approximately 2% of the total volume of ocean water. The surface zone usually ranges between depths of 500 feet to 3,300 feet below ocean surface, but this can vary a great deal.
A hypha (plural hyphae, from Greek á½ÏÎ®, huphá¸, âwebâ) is a long, branching filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Yeasts are unicellular fungi that do not grow as hyphae.
The sequestered fragment is often close by, but in some instances can travel quite far from the original location of the extrusion, especially when trauma is the cause of the rupture. This condition is also called a sequestered extrusion, a sequestered fragment or simply a sequestered disc.This article will examine some of the lesser known facts about disc sequestrations, including what happens to disc fragments which float freely in the spinal anatomy.equestered Disc Definition. Sequestrations are the most severe form of disc rupture, but are statistically no more problematic than normal ruptures or extrusions in which the nucleus fragment remains attached to the disc.
