摘　　要：目的了解人颅顶骨顶结节与其内面脑结构的相关关系。方法 32例福尔马林固定教学用头部标本,锯开颅骨,取脑后,肉眼观察确定颅顶骨顶结节和大脑半球顶叶外侧面隆凸,游标卡尺和软尺分别测量左右顶结节之间、两侧大脑半球顶叶外侧面隆凸之间的直线距离和实际距离,测量数据作相关性分析。结果大脑半球顶叶外侧面有一隆凸,由缘上回及附近脑回构成。与颅顶骨顶结节之间存在相关关系(r=0.639,P<0.05)。结论大脑半球顶叶外侧面存在一个恒定的隆凸,其位置相当于颅顶骨顶结节的内面。Objective To investigate the relationship between the parietal tuberosity of skull and the corresponding structures inside tuberosity. Methods 32 embalmed brains were observed to identify the location of the parietal tuberosity and the lateral protuberance the parietal lobe; vernier caliper and rule were used to measure the length between the left and right parietal tuberosities, and the left and right protuberances of the parietal lobes, respectively, the obtained data were then used for correlated analysis between the tuberosity and the protuberance. Results There is a constant lateral protuberance in the parietal lobe, which was composed of the supramarginal gyms and its surrounding gyrus. The presence of the parietal tuberosity and the lateral protuberance of the parietal lobe was correlated. （r=0.639,P〈0.05）. Conclusions A protuberance can be found on the lateral surface of parietal lobe of the cerebral hemisphere,deep to the parietal tuberosity.
