Morphology and Distribution of Lamellar Corpuscles in the Mesentery of the Cat

摘要

Mesentery samples obtained from 13 mixed breed cats were stereoscopically and microscopically examined and yielded the following results. In the mesentery, lamellar corpuscles were densely distributed around blood vessels, with a mean number of 182.2 +/- 20.9 and mean maximum and minimum diameters of 0.98 +/- 0.18 mm and 0.54 +/- 0.08 mm, respectively. While most lamellar corpuscles were isolated, some complex lamellar corpuscles were found in the mesentery. Lamellar corpuscles in the mesentery appear to serve more as internal receptors that detect changes in the internal environment than as external receptors. In addition, those found around blood vessels in the mesentery are likely to be involved in blood pressure regulation.
