Robert HI，Ian S.Curthoys，和Charles H.猫半规管的平面关系。上午好。223(1)：55-62。1972年。最小二乘和最小二乘。对猫的骨迷路上的一系列点进行了ENT分析，得到了半规管平面的数学描述。然后计算三个同侧骨平面之间、对侧管平面之间的夹角，以及由立体定位平面和椎管平面形成的夹角。结果表明，同侧根管平面是垂直的，对侧协同作用的两个根管近似共面。水平管面与水平面成22.92‘角。文中还给出了最佳位置和热刺激.自然半规管定位的管面；角度；热量刺激；自然刺激；管轴；立体定位参考。几位作者研究了身体旋转对顶盖-内淋巴系统作用力的数学处理(9，10，20，24，25，26)。根据这样的计算对受体反应的评估将受益于了解颅骨内管状平面的准确方向，并可靠地参照颅骨外界标。此外，这些知识将提高对迷宫控制眼睛和头部运动的理解(2，3，21，22)。文献中还没有完整的描述猫半规管之间的平面关系，以及导管和立体定位平面之间的平面关系。由于运河的尺寸很小，这种类型的测量很困难。其中一些信息包含在费尔南德斯和瓦伦蒂努齐的一篇论文中(7)。他们对困难的解决方案。在测量Sm中的Ty。所有11个平面结构都是将从垂直肛门获得的点投射到水平立体定位平面。然后根据生成的线条计算角度关系。然而，可以证明，这种技术将产生误差，除非管平面垂直于其投影到的平面；并且，如本文所示，垂直半规管并不垂直于水平立体定位平面。
ROBERT HI, IAN S. CURTHOYS, AND CHARLES H. Planar relationships of semicircular canals in the cat. Am. 223 (1): 55-62. 1972. Least-square and princi-. ent analyses were applied to a series of points obthe osseous labyrinth of the cat, resulting in a mathematical description of the semicircular canal planes. After this, angles were calculated between the three ipsilateral ca nal planes, between pairs of contralateral canal planes, and those formed by the stereotaxic planes and the canal planes. Results indicated that ipsilateral canal planes were orthogonal and that pairs of contra-lateral synergistically acting canals were approximately coplanar. Horizontal canal planes formed angles of 22.92’with the horizontal plane. The optimal position of and caloric stimulation are also given. canal planes for natural semicircular canal orientation; angles; caloric stimulation; natural stimulation; canal axes; stereotaxic reference.MATHEMATICAL TREATMENT of the forces acting on the cupula-endolymph system induced by body rotations have been investigated by several authors (9, 10, 20, 24, 25, 26). Evaluation of receptor responses based upon such calculations would be benefitted by knowledge of the precise orientation of the canal planes within the skull, reliably referenced to external skull landmarks. Further, such knowledge would improve understanding of labyrinthine control of eye and head movements (2, 3, 2 1, 22). A complete description of the planar relationships among the semicircular canals and between the canals and the stereotaxic planes in the cat has not appeared in the literature. Measurements of this type are difficult because of the small size of the canals. Some of this information was contained in a paper by Fernandez and Valentinuzzi(7). Their solutio n to the difficul. ty in measuring sm. a11 plana r structures was to project points obtained from the vertical C anals into the horizontal stereotaxic plane. Angular relationships were then calculated from the lines generated. However, it can be shown that error will result from such a technique unless the canal plane is perpendicular to the plane into which it is projected; and, as will be shown in this paper, the vertical semicircular canals are not perpendicular to the horizontal stereotaxic plane.
