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.
The bursa forms a soft cover over the elbow tip and allows the skin to glide smoothly when one bends and extends the elbow. When it becomes inflamed, sometimes from a repetitive task or a direct bump, the bursa can produce more fluid. This leads to swelling and a painful bubble at the elbow tip.
