the nerve is completely separated, like with a cut nerve. Both a fourth and fifth degree injury require surgery for recovery. A sixth degree injury is a combination the other types of nerve injury and recovery and treatment will vary depending on which type of nerve injury is present. Nerve Recovery and Regeneration Following nerve injury, the nerve will try to repair itself by sprouting regenerating nerve units. These regenerating units will then try to grow down the nerve to reinnervate muscle or skin. If they make a correct connection, motor nerve to muscle or sensory nerve to skin, then recovery of muscle function
The movement of particle (random) suspended in a fluid is called Brownian motion. Brownian motion's mathematical model has several applications in real world. This theory is closely related to that of normal distribution.
Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.hen a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration. For example, if the cell is submerged in saltwater, water molecules move out of the cell. If a cell is submerged in freshwater, water molecules move into the cell.
