The medial splayed bone is a part of the human skeletal system, which is located at the midpoint from the anterior midline to the midline of the spine. The position is determined by the midpoint of the connecting line between the sternal stalk and the navel. The sternal stalk is a part of the sternum, located above the sternum, and the navel is located in the center of the abdomen. Connect two points and find the midpoint of the connecting line, which is the position of the internal splayed bone.
