Postcentral

释义 Definition

postcentral(形容词):解剖学/神经科学用语,指位于“中央沟(central sulcus)之后”的,常用来描述中央后回(postcentral gyrus)及其相关区域(主要与躯体感觉处理有关)。该词在专业语境中最常见;在日常英语中较少单独使用。

发音 Pronunciation (IPA)

/postsntrl/

例句 Examples

The postcentral gyrus processes touch and pressure.
中央后回负责处理触觉与压力等感觉信息。

Damage to the postcentral cortex can impair fine tactile discrimination even when muscle strength is normal.
即使肌力正常,中央后皮层受损也可能导致精细触觉辨别能力下降。

词源 Etymology

由前缀 post-(“在……之后”)+ central(“中央的”)构成。post- 源自拉丁语 post(after,“之后”),central 与拉丁语 centrum(中心)相关。整体字面义即“中央之后的”,在解剖定位中用于表示相对“中央沟/中央区域”更靠后的结构。
