The Division Lycopodiophyta (sometimes called Lycophyta or Lycopods) is a tracheophyte subdivision of the Kingdom Plantae. It is the oldest extant (living) vascular plant division at around 410 million years old.hese species reproduce by shedding spores and have macroscopic alternation of generations, although some are homosporous while others are heterosporous. Members of Lycopodiophyta bear a protostele, and the sporophyte generation is dominant.
Injury or inflammation of a bursa around the shoulder joint causes shoulder bursitis. What causes shoulder bursitis? A bursa can become inflamed from injury, infection (rare in the shoulder), or an underlying rheumatic condition.
Only when the deposit becomes large enough to pinch between the bones when the shoulder is elevated does it cause pain. Sometimes smaller deposits cause pain if they become acutely inflamed, especially when the calcium salts leak from the lesion into the sensitive bursal tissues.
