File:E&S 1911 C-S key III.png

This Key-figure represents a mesial sagittal section of the head and greater portion of the neck. It is largely a reconstruction from the sections, but some details, especially of the brain, hare been obtained by cutting the sections in the mesial sagittal plane, superimposing them, and then confirming and correcting the reconstruction. The solid lines 2–18 indicate the lines of the principal sections, while the broken lines 1'–10' indicate the levels of the horizontally bisected sections. The solid lines indicate the levels on the left side, while the broken lines show the levels of the sections on the right side. It should be stated that in this subject the sphenoidal sinuses are very small and bilaterally placed. Certain structures which are unlabeled need a word of explanation: the stalk of the infundibum connects the hypophysis with the third ventricle; the oculomotor nerve is shown extending obliquely across the interpeduncular fossa; the tentorium cerebelli, extending over the cerebellum, is partially shown. The gyrus lingualis in this subject extends to the region indicated. The venous sinuses of the dura are not shown. Note.—The leader labeled "Recessus opticus" ends slightly above the optic recess.
