The mixed, seromucous sublingual gland contains mostly mucous gland tubules [1. The tubules often branch out, as they do in this figure. There are serous demilunes [2 at the ends of the tubules (cf. Fig. 382-384). The tubules are filled with mucus and often distended. Note the different shapes of the nuclei. In cells from mucous glands U, the nuclei are mostly small and £ spindle-shaped. The nuclei of serous gland cells [3 are large and round. The ■ft nuclei of mucous and serous cells, both are in basal positions (cf. Fig.387). An interlobular duct 13 embedded in coarse connective tissue El is seen at the ^ left edge of the figure. A vein H is located underneath the duct. Intercalated '-C ducts are not sectioned. oi
