Which of the following is the correct location for SP-3?

SP-3, also known as "Taibai," is located in the depression distal-inferior to the first metatarsophalangeal (MTP) joint. This specific placement is essential for practitioners of acupuncture, as it lies on the Spleen meridian, which is linked to functions such as digestion and the transformation of nutrients.

The positioning of SP-3 in relation to the first MTP joint allows practitioners to access this acupuncture point effectively for therapeutic interventions aimed at improving Spleen-related issues. Being situated in a depression makes it easier to locate during an acupuncture session. It is fundamental for a practitioner to have an accurate understanding of the anatomical landmarks surrounding this point for effective needle insertion.

Other options indicate anatomically different locations, which would not correspond to SP-3, making them unsuitable for targeting the correct point. Understanding the precise location of acupuncture points is crucial for effective treatment in acupuncture practice.
