The dimensions of the skull and the dry weight of the skull bones show definite sexual dimorphism. The dynamics of the growth in the skull dimensions and their vectorial presentation show that skull growth in Rattus norvegicus BERKENHOUT is most rapid between the 42nd d and the 4th month of life. This phase is followed by a phase of localized bone growth, which persists up to an age of 300 d. The faster growth of the viscerocranium leads to changes in the proportions of the skull. The relative positions of viscerocranium and mandible and the higher relative position of the dentures are similar to principle to those seen in man. Finally, the morphogenetic effect of the temporalis muscle together with that of the brain in the shaping of the skull are discussed.
颅骨的尺寸和颅骨骨骼的干重呈现出明显的性别二态性。颅骨尺寸的生长动态及其矢量表现表明，褐家鼠（Rattus norvegicus BERKENHOUT）颅骨在出生后第42天至第4个月期间生长最为迅速。此阶段之后是局部骨骼生长阶段，该阶段一直持续到300日龄。面颅骨的较快生长导致了颅骨比例的变化。面颅骨和下颌骨的相对位置以及齿列较高的相对位置在原理上与人类相似。最后，讨论了颞肌与大脑在颅骨塑形过程中的形态发生作用。
