The SA Node is the heart's normal pacemaker. When the SA Node depolarizes, electrical signal spreads through the atrial muscle causing contraction.
Explanation:
Inherent rhythmicity / automaticity - The property of the pacemaker cells of the heart to start electrical sequence of depolarization and repolarization.
SA Node or Sino-atrial Node generates the electrical signal.
The electrical signal passes through internodal pathways, atrial fibres, atrioventricular node (AV Node), the bundle of His, Purkinje fibres, right bundle branch, left bundle branch.
Systole - Contraction of cells when the electrical signal of depolarization reaches the contractile cells.
Diastole - Relaxation of cells when the electrical signal of repolarization reaches the myocardial cells.

Relax... Your mouth does not have the vasculature that would allow you to bleed out. By this time some healing should have formed but it would still be a raw wound. The best thing you should do is press gauze on the wound, as well as put some alcohol, just to keep out infection. Just see your doctor in the morning.
Your mouth if anything should be fine.

Answer:
Rugby is a contact sport that is played between two opposing teams made up of 15 players each, with the aim of taking an oval ball to the rival's goal line. The ball cannot be passed forward, but always backwards, so it is important that the players have forward strokes to advance with the ball, which can be touched with any part of the body, although in the game the hands are mostly used. At the same time, it is a very hard and rough sport, since impacts through tackles are the main form of defense, with which there are usually certain injuries in the development of matches.
It is a sport of British origin, although it is also very popular in France, Oceania and Argentina. Being such a massive sport, it does not allow us to discover a culture so deeply rooted in the sport itself, although the chivalry of the game is a factor attributed to British culture.
