许多吸食性鱼类使用神经颅抬高来扩大口腔进行吸食性，这一运动必然伴随着轴向骨骼关节的背屈。轴向骨骼能承受多少背屈以及在哪里发生背屈可能因轴向骨骼形态、体型和神经颅抬高的运动学而异。我们测量了三种具有不同身体形态的物种的三维神经颅骨运动学：侧向压缩的外侧Embiotoca lateralis，梭形小翼鱼和背侧压缩的armatus Leptocottus。骨占据神经颅骨尾侧的面积分别为42±1.5%、36±1.8%和22±5.5%（平均值±s.e.m； N=3、6、4），外轴深度也由侧棘棘向长棘棘递减。每个物种的最大神经颅抬高度分别为11°、24°和37°，这与轴向形态和体型可能限制神经颅抬高度的假设一致。神经颅抬高的平均旋转轴位置分别接近第一、第三和第五椎间关节，导致假设与椎间关节屈曲的数量有类似的关系。虽然未来的工作必须检验这些假设，但我们的结果表明，这些关系值得进一步探究。摘要：轴向骨骼形态和身体形状方面与三种物种的3D神经颅运动相关，产生轴向形状如何影响鱼类颅运动的假设。
Many suction-feeding fish use neurocranial elevation to expand the buccal cavity for suction feeding, a motion necessarily accompanied by the dorsal flexion of joints in the axial skeleton. How much dorsal flexion the axial skeleton accommodates and where that dorsal flexion occurs may vary with axial skeletal morphology, body shape and the kinematics of neurocranial elevation. We measured three-dimensional neurocranial kinematics in three species with distinct body forms: laterally compressed Embiotoca lateralis, fusiform Micropterus salmoides, and dorsoventrally compressed Leptocottus armatus. The area just caudal to the neurocranium occupied by bone was 42±1.5%, 36±1.8% and 22±5.5% (mean±s.e.m.; N=3, 6, 4) in the three species, respectively, and the epaxial depth also decreased from E. lateralis to L. armatus. Maximum neurocranial elevation for each species was 11, 24 and 37°, respectively, consistent with a hypothesis that aspects of axial morphology and body shape may constrain neurocranial elevation. Mean axis of rotation position for neurocranial elevation in E. lateralis, M. salmoides and L. armatus was near the first, third and fifth intervertebral joints, respectively, leading to the hypothesis of a similar relationship with the number of intervertebral joints that flex. Although future work must test these hypotheses, our results suggest the relationships merit further inquiry. Summary: Aspects of axial skeletal morphology and body shape correlate with 3D neurocranial motions in three species, generating hypotheses of how axial shape may impact cranial motions in fishes.
