Synonym: abnormal Henson's node morphology
Synonym: abnormal primitive knot morphology
Synonym: abnormal prochordal knot morphology
Synonym: abnormal Spemann's organizer morphology

Definition: any structural anomaly of the regional thickening of cells at the rostral tip of the vertebrate primitive streak through which gastrulating cells migrate anteriorly to form tissues in the future head and neck; this region organizes the formation of the three embryonic layers and establishes the longitudinal axis and the polarity of the embryo
