Fig. 3. Profile view of neuro-cranium, visceral cranium, and upper part of neck skeleton

The cartilage is everywhere "stippled."

  • A.C. - auditory capsule
  • A.T. - ala temporalis or pars zygomatica (the third division of the 5th nerve is seen crossing its outerside)
  • C. - cricoid cartilage
  • C.Ty. - chorda tympani nerve
  • C2 - neural arch of second cervical vertebra
  • C3 - neural arch of third cervical vertebra
  • C.B. - connective tissue bar which forms part of outer wall of orbit which will later ossify to complete the malar bone and external angular process of the frontal bone
  • E.P. - ethmoidal plate
  • F. - frontal bone
  • I.C. - internal carotid artery
  • H. - cerato-, epi-, stylo- and tympano-hyal
  • G.O.N. - great occipital nerve passing backwards from second cervical nerve
  • L.D. - lacrymal duct
  • L.N.P. - lateral nasal process
  • Ma. - malar bone (behind and deep to it the palate bone is seen)
  • Mn. - mandible with Meckel's cartilage (Mt.) running backwards from it and forming malleus cartilage
  • Mx. - maxilla - showing the infraorbital groove through which the infraorbital nerve is running
  • N.C. - nasal capsule
  • O.P. - ala orbitalis or lesser wing pointing backwards towards P.P. the parietal plate
  • P.P. - parietal plate
  • S.O.M. - spino-occipital membrane
  • S.Z. - squamoso-zygomatic
  • T.S. - tectum synoticum
  • T.F. - temporal fossa limited behind and above by a groove
  • V. - vacuity caused by large vein or extravasation
  • V.S. - vagus and sympathetic ganglion.

Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.     (More?
