至少有三种类型的运动，背腹屈曲和伸展，轴向旋转和侧弯，发生在颈椎的每个椎间关节。在前两个颈椎骨之间，平均轴向旋转为107.5 °，这是颈椎总轴向旋转的73%。寰枕关节平均旋转27 °，而其余的颈部关节各自小于3 °。旋转运动。背腹屈曲和伸展在寰枕关节处最大，振幅为86.4 °。占颈椎背腹侧运动总量的32%。横向弯曲沿着颈部长度相对更均匀，平均值范围为25 °至45 °。对于每个关节，除了前两个颈椎之间的关节，其平均值仅为3.9 °。横向弯曲。
At least three types of movement, dorsoventral flexion and extension, axial rotation and lateral bending, were shown to occur at each of the intervertebral joints in the cervical spine. Between the first two cervical vertebrae the mean axial rotation was 107.5.degree.c which was 73 per cent of the total axial rotation of the cervical spine. The atlantooccipital joint rotated through a mean of 27.degree., whereas the remaining cervical joints each had less than 3.degree. of rotatory movement. Dorsoventral flexion and extension were maximal at the atlantococcipital joint, which had an amplitude of 86.4.degree. and accounted for 32 per cent of the total dorsoventral movement of the cervical spine. Lateral bending was relatively more uniform along the length of the neck, with mean values ranging from 25 to 45.degree. for each joint except that between the first two cervical vertebrae, which had a mean of only 3.9.degree. of lateral bending.
