The Anatomical Relationship Between Acupoints of the Face and the Trigeminal Nerve
Bibliographic record
Abstract
Objective: Acupuncture continues to gain popularity as a first treatment option for a variety of conditions; however, an in-depth understanding of the relationships between the acupoints and the underlying anatomy of the human body is often unclear. This article updates the anatomical relationship between facial acupoints and the trigeminal nerve (CN V) and contrasts the results against the standard textbook Chinese Acupuncture and Moxibustion . Methods: A literature review, cadaver dissection, and a neuroanatomical stimulation of the CN V was conducted, focusing on the anatomical locations of the acupoints along the CN V on the face and nerve block targets. The results were contrasted against the standard acupoint location and nerve targets described in Chinese Acupuncture and Moxibustion . Results: The present article classifies CN V acupuncture targets according to 4 different types: (1) trunk; (2) bifurcation; (3) branch; and (4) anastomoses. The results of this exploration highlight the specificity with which acupoints are located in relation to the CN V. Areas of high nerve density correspond to several acupoints. Consequently, acupoints overlay closely with CN V branches as they emerge and bifurcate on the face. Conclusions: There is a clear and neuroanatomically relevant relationship between facial acupoints and the CN V.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
