The movement of Ascaris suum sperm cells is caused by protrusive, adhesive and contractile forces that act inside the cell. A discrete, 2-D geometric model of the forward motion and turning of the cell is modeled in this paper. The general assumption used is that the internal pH level of the lamellipod is responsible for motility. The main focus of this model is the protrusion of the front boundary of the cell, although contractile and adhesive forces are present in the model. This model only considers MSP bundles because they appear to be responsible for protrusion, and they make up the framework for the shape of the lamellipod.
