组织形态学和组织化学方面的下颌角软骨及其周围的软骨膜的材料组成的46只大鼠年龄在1和56天。在11-13天与下颌髁状突软骨的比较揭示了它们的一般组成的显著一致性。然而，构成软骨的亚区的程度存在某些差异。这些差异被认为是表达结构之间生长速率的差异。发生在下颌角软骨的年龄变化的研究揭示了一个与年龄相关的变化方向的肌肉连接到中间和侧面的结构，在组合的方向的变化，结缔组织覆盖其后部。这种变化可能是作用在软骨上的张力方向变化的指示。最终，它们可能与结构的有限的临时维护有关。
Histomorphological and histochemical aspects of the mandibular angular cartilage and its surrounding perichondrium are described from a material consisting of 46 rats aged between 1 and 56 days. Comparisons at 11-13 days with mandibular condylar cartilage reveal a marked concordance in their general composition. However, certain differences in extent of the subzones constituting the cartilage are present. These differences are suggested to express differences in growth rates between the structures. The study of the age changes which take place in the mandibular angular cartilage reveals an age-related change in direction of the muscles attached to the medially and laterally facing surfaces of the structure in combination with a change in direction of the connective tissue covering its posterior part. Such changes might be indications of changes in direction of the tensional forces acting on the cartilage. Ultimately, they might be related to the limited temporal maintenance of the structure.
