The mandibular joint (MJ) and masticatory muscles in 15 domestic pigs, aged 1 year, were investigated during and after dissection. The joint consisted of a fossa, disc and condyle surrounded by a ligamentous capsule. The fossa was almost flat, slightly convex antero-posteriorly and concave medio-laterally; the disc was biconcave and the condyle oval. The long axis of the condyles formed an anteriorly orientated angle to the frontal plane. The masticatory muscles were similar to human ones except for the pig zygomatico-mandibular muscle. The resemblance between the anatomy of the porcine and human joint and masticatory muscles makes the pig a useful animal for functional studies of the masticatory system.
对15只1岁家猪的下颌关节(MJ)和咀嚼肌在解剖过程中和解剖后进行了研究。该关节由一个窝、盘和髁组成,周围有一个韧带性关节囊。窝几乎是平的,前后略凸,内外侧凹陷;盘是双凹的,髁是椭圆形的。髁的长轴与额平面形成一个向前的角度。除猪颧下颌肌外,咀嚼肌与人类的相似。猪和人类关节及咀嚼肌解剖结构之间的相似性使猪成为咀嚼系统功能研究的有用动物。
