Asymmetry in the Bone Weight of the Mandibula and Limbs of Rabbits

Asymmetry in the Bone Weight of the Mandible and Limbs of Rats

“…This implies that the phenomenon of right-left asymmetry in bone weight is least prominent in the bones that are directly joined at the sagittal plane. In our previous study using rabbit [8], right-left asymmetry was observed in the same bones as listed above. Whereas it was found in the limbs of rat and not in rabbit that the degree of the difference in scapula, one of the shoulder girdle was the greatest among other bones.…”

Asymmetry in the Bone Weight of the Rabbit Mandible

“…Correlation of the weights between the mandible and the teeth . and the teeth existed not only in young but also adult animals (as a result of the bone of the extremities which was presented in the previous paper) [5]. HRDLICKA pointed out that the causes of the side difference in human mandible would be connected with the function and habit of mastication [3].…”

“…Group I composed of forty young rabbits consisting of males and females of the same number (body weight, around 1.9kg) and Group II consisted of twenty adult female rabbits (body weight, around 2.7kg). Their mandible and teeth preparations were obtained by the same procedure as in the previous paper [5]. The weight of the mandible with teeth, of the mandible without teeth and of the teeth were measured to the nearest mg by a single-pan balance (SHIMADZU) sensitive to 0.01mg.…”
