Amphicentric
Definition
Disposed concentrically on both sides or around a central core; in plant histology and anatomy, it describes a type of fibrovascular bundle where either the woody tissue (xylem) or the phloem completely surrounds the other structural component. Additionally, in neurology or optics, it can refer to fibers or light beams converging or diverging symmetrically around a common focal point.
