[Asymmetry of the neuronal organization of the cat stellate (cervicothoracic) ganglion in the postnatal period of ontogenesis].
By direct and indirect morphometry the cell density maximal diameter and area of section of neurocytes in the zones of the emergence of the basic nerves and in the centre of the stellate ganglion were determined in kittens of various ages and adult cat. There is an increase of the maximal diameter, average area of section of neurons (16.98 +/- 0.07 mm and 132.2 +/- 0.9 mm2 in newborn, 21.7 +/- 0.72 mm and 31.4 +/- 2.6 mm2 in 10-days, 6.69 +/- 0.5 mm and 355 +/- 2.4 mm2 in 20-days kitten, 4.86 +/- 0.6 mm and 634 +/- 36 mm2 in adult cat and reduction of cell density of ganglionic neurons in postnatal ontogenesis. In newborn kitten, kittens of 10- and 20-days of age and adult cat larger neurons were located in the cranial part of the ganglion. In 10 and 20 days kittens and adult cats an asymmetry between right and left stellate ganglia in the maximal diameter and average area of section of neurons was revealed. In adult cat the asymmetry in the cell density was also found between both ganglia.
