Which points are associated with metopism caution?

The points associated with metopism caution are located on the Governor Vessel (Du Mai), which runs along the midline of the head. Metopism is the condition where the frontal bone does not fuse properly, leading to a persistent metopic suture. This can create a higher risk of injury to the underlying structures when needling in that area.

When considering the correct choice, Du23 and Du24 are located on the forehead, closely related to the region where the metopic suture resides. Needling in this area requires caution, particularly in individuals with metopism, as there is an increased risk of damaging important structures, like the frontal lobe and associated vessels. Thus, understanding the anatomical landmarks and possible variations in cranial suture formation is essential for safe acupuncture practice.

While the other options include points along the Governor Vessel, they either do not directly correlate with the area of concern for metopism or are situated further back or lower on the head, where the risk is less pertinent to the condition. Therefore, the focus on Du23 and Du24 emphasizes the importance of anatomical awareness and caution in clinical practice regarding specific cranial variations.
