Healthy, adult, male and female goat temporomandibular retrodiscal tissues were characterized to determine if biochemical differences existed between the genders. RNA concentrations were not different between male and female retrodiscal tissues; however, the DNA concentration in female retrodiscal tissues was 82% greater than in male retrodiscal tissues. Collagen concentrations were significantly greater in male retrodiscal tissues, and this was reflected in significant gender differences of type I and III collagen concentrations. More specifically, male temporomandibular retrodiscal tissues contained 70% more type I collagen and 119% more type III collagen when compared to female retrodiscal tissues. These differences in collagens and DNA reflect a gender difference in temporomandibular retrodiscal tissue composition that underlies divergent biomechanical and neurophysiological properties.
对健康成年雄性和雌性山羊的颞下颌关节盘后组织进行特性分析，以确定两性之间是否存在生化差异。雄性和雌性盘后组织中的RNA浓度没有差异；然而，雌性盘后组织中的DNA浓度比雄性盘后组织高82%。雄性盘后组织中的胶原蛋白浓度显著更高，这反映在I型和III型胶原蛋白浓度的显著性别差异上。更具体地说，与雌性盘后组织相比，雄性颞下颌关节盘后组织中的I型胶原蛋白多70%，III型胶原蛋白多119%。胶原蛋白和DNA的这些差异反映了颞下颌关节盘后组织组成的性别差异，这是不同生物力学和神经生理特性的基础。
