The distribution and size of hemidesmosomes on the basal cell membrane adjacent to the basement lamina and desmosomes on the spinous cell membranes were compared in the attached gingiva, hard palate, tongue, alveolar mucosa, and buccal mucosa of the vervet monkey. The lengths of the sectioned cell membranes and pooled desmosome lengths were measured on photomicrographs of basal and spinous cells printed at standard magnification. The mean desmosomal length, interdesmosomal distance, and percentage cell membrane occupied by desmosomes was calculated. It was found that the percentage cell membrane occupied by hemidesmosomes was significantly higher in the basal cells of the attached gingiva and palate than in the alveolar mucosa, buccal mucosa, and tongue. In the spinous cell layer the percentage cell membrane occupied by desmosomes and the desmosome length was significantly higher in the tongue, attached gingiva, and hard palate than in the alveolar mucosa and buccal mucosa.
