abstract
Present study was conducted on the buccal cavity of stump-tailed monkey. The hard palate formed the roof of the cavity. It was of uniform width rostro-caudally. It presented transverse ridges (8 pairs) which were smooth and concave posteriorly. Between 1^st pair of ridge and upper incisors was located bottle shaped elongated papilla incisive. The total length of the hard palate was 6.5 cm. The width of the hard palate was 2.2 cm rostrally, 2.9 cm in middle and 2.4 cm posteriorly. The dorsal surface of tongue presented “C” shaped impressions corresponding to the transverse ridges of the hard palate. From the ventral surface of the tongue arise single median frenum linguae. The apex was rounded. The dorsal surface was devoid of torus linguae and lingual fossa. Fungiform papillae were numerous towards the apex. Vallate papillae (2 pairs) were distinct and located near the root of the tongue. The root was connected to the soft palate by two lateral palate-glossal arches. The length of the tongue was 7.8 cm. The width of the tongue was 1.93 cm rostrally, 2.65 cm in middle and 2.01 cm posteriorly. Floor of the cavity consisted pre-fsrenular part and two lateral sublingual recesses. Pre-frenular part was narrower rostrally but widens towards frenum linguae. Each halve of the lower and upper jaw presented two incisors, one canine and five cheek teeth. The upper canines were much longer than the lower canines. Diastema was absent.
