Summary
Absence of the ansa cervicalis was noticed in only one out of 200 cadavers, and that only on the right side, where it was replaced by the vagocervical complex. This complex was formed by the vagus nerve with the C1 and C2 components from the cervical plexus, giving off a descending branch to supply the infrahyoid muscles of the neck.
Résumé
Sur un cadavre parmi deux cents et uniquement du côté droit, nous avons relevé l'absence de l'anse cervicale, remplacée par un complexe vago-cervical. Ce complexe était formé par le n. vague et des rameaux communicants issus des racines C1 et C2 du plexus cervical, et abandonnait une branche descendante, innervant les mm. infra-hyoïdiens.
