Using a front close implies that this A part of the human body encounters stimuli, including food, favouring cephalisation, the event of the head with sense organs and also a mouth. Several bilaterians have a mix of circular muscles that constrict the human body, which makes it for a longer period, and an opposing set of longitudinal muscles, that shorten the human body;[135] these empower soft-bodied animals by using a hydrostatic skeleton to maneuver by peristalsis.
