Hydromyelia is a medical condition that involves widening of the intraspinal cavity or is a marked dilatation of the central spinal canal. The central canal of the spinal column is the main area of affectation that results to increased pressure due to fluid accumulation.
dangling participle - a participle (usually at the beginning of a sentence) apparently modifying a word other than the word intended: e.g., `flying across the country' in `flying across the country the Rockies came into view'.
DANGLING MODIFIER: When we begin a sentence with a modifying word, phrase, or clause, we must make sure the next thing that comes along can, in fact, be modified by that modifier. When a modifier improperly modifies something, it is called a dangling modifier.. This often happens with beginning participial phrases, making dangling participles an all too common phenomenon. In the sentence below, we can't have a car changing its own oil.
