摘要:

In 2 cats nerves of the spinal pia mater were studied by means of electron microscopy. These nerves possessed no perineurium. However, it has been observed that flat cells of the surrounding connective tissue can form an incomplete covering for small nerve bundles. In addition the perivascular nervous plexus of subarachnoid arteries of the brain stem, which were examined in 1 animal, also showed no perineural sheath. These results are discussed with those reported in the literature dealing with the perineurium of other peripheral nerves. The observations concerning the distribution and the composition of leptomeningeal nerves are in accordance with those obtained by light microscopic investigations.

摘要:

Moiré photographs of the occlusal surface of first molars of Japanese children were taken by means of a specially designed moiré contourograph apparatus. They were then used for three-dimensional measurements. The heights of 4 cusps and some other points were measured by counting contour lines. Distances and angles between them were also measured. Sex differences of these measurements are found mainly around the metacone and hypocone. There is no clear correlation of the four cuspidal heights to the distances between the
