Types of glandular acini and number of mucous, serous acini and demilunes were also counted.
Some of the mucous acini on were capped by basophilic cells, as crescent shape demilunes (Fig .3).
The mean number of serous demilunes in "a" and "b" parts of right and left gland was calculated and their difference was statistically insignificant (p Greater than 0.05, table-1).
After pooling the data difference between the mean number of acini, demilunes, ducts and the mean diameter of the ducts of right and left glands was found to be statistically insignificant.
Some of the mucous acini were capped by serous cells called demilunes. This finding was similar to that of Ichikawa and Ichikawa14, but not in agreement with the findings of Eversole12 that in human sublingual glands demilunes have seromucous cells.
The sublingual glands are mixed (Fig.2), composed of mucous acini with scattered serous demilunes. The mucous cells possess spongy cytoplasm and flattened and basal nuclei.
The mucous acini have clear cellular limits; the nuclei are confined to the basal cytoplasm and are capped by large serous demilunes. The acinar lumen is small and irregular.
5), been almost exclusively formed by mucous acini with scarce and small serous demilunes. The mucous cells were only slightly stained whit AB and reacted strongly to PAS.
