Examples

  • Oncology (NF 2 patients and NF 1 patients with active tumors/large plexiform neurofibromas):

    Appointments

  • Dr. Fisher is also using PET and MRI techniques to predict the clinical behavior of plexiform neurofibromas, the largest and most important tumors seen in neurofibromatosis.

    Pediatric cancer research

  • The Children's Hospital Division of Oncology sees NF 2 patients, as well as NF 1 patients with active tumors (under therapy) or large plexiform neurofibromas.

    Neurofibromatosis

  • Thus, on a plexiform mass of this kind being cut across, the first impression is, that a great number of arterial branches or arteries have been divided, whilst in fact the entire plexus seems to be formed of one artery.

    Journal of the Proceedings of the Linnean Society - Vol. 3 Zoology

  • The anterior jugular vein, 3, also occupies this region below; while some venous branches, which join the external and internal jugular veins, traverse it in all directions, and present obstacles to the operator from their meshy plexiform arrangement yielding, when divided, a profuse haemorrhage.

    Surgical Anatomy

  • They form a plexiform net-work in the mucous membrane, and are then collected into about twenty branches, which pierce the cribriform plate of the ethmoid bone in two groups, a lateral and a medial group, and end in the glomeruli of the olfactory bulb (Fig. 772).

    IX. Neurology. 5a. The Olfactory Nerves

  • They form intricate plexuses upon the surfaces of the larger trunks, and run along the smaller arteries as single filaments, or bundles of filaments which twist around the vessel and unite with each other in a plexiform manner.

    V. Angiology. Introduction

  • Their dendrites undergo extensive ramification in the inner plexiform layer.

    X. The Organs of the Senses and the Common Integument. 1c. 1. The Tunics of the Eye

  • The inner processes of the cone bipolars ramify in the inner plexiform layer in contact with the dendrites of the ganglionic cells.

    X. The Organs of the Senses and the Common Integument. 1c. 1. The Tunics of the Eye

  • The outer plexiform layer is much thinner than the inner; but, like it, consists of a dense net-work of minute fibrils derived from the processes of the horizontal cells of the preceding layer, and the outer processes of the rod and cone bipolar granules, which ramify in it, forming arborizations around the enlarged ends of the rod fibers and with the branched foot plates of the cone fibers.
