Fig. 1. Part of the reconstructed head of the Bryce 30 mm embryo as seen from the front and left side

  • A. - ant. limb of ala orbitalis
  • A.O. - outer end of ala orbitalis of sphenoid
  • A.T. - ala tenmporalis - perforated by superior maxillary nerve
  • C. - connective tissue bar over nasal capsule in which nasal bones and internal angular processes of frontal bones will develop
  • F. - frontal bonie
  • L.D. - lacrymal duct
  • L.N.P. - lateral nasal process
  • I.O.N. - infraorbital nerve
  • M. - maxilla
  • Ma. - malar bone at lower end of vertical bar of connective tissue which is perforated by temporo-malar nerve
  • M.G. - Meckel's ganglion
  • O.P. - part of outer wall of orbit formed by connective tissue and which later ossifies to form the orbital plate of the great wing of the sphenoid
  • P. - posterior limb of ala orbitalis (lesser wing of sphenoid) between A and P notice optic nerve.
  • P.P. - parietal plate
  • S.E.C. - ethmoidal or spheno-ethmoidal plate.
