Abstract
Wilfred M. and Lee D. L. 1981. Observations on the buccal capsule and associated glands of adult Bunostomum trigonocephalum (Nematoda). International Journal for Parasitology 11: 485–492. The buccal capsule or stoma of Bunostomum trigonocephalum is a large, cuticular-lined structure. The head of the nematode lacks distinct lips and has a large ovoid mouth which is partly occluded by a pair of sub-ventral cuticular plates which arise from the wall of the buccal cavity. A pair of sub-ventral lancets or basal onchia are situated at the base of the buccal cavity and a dorsal tooth arises from the base of the buccal cavity and extends forwards to terminate just inside the mouth. A duct lies within this dorsal tooth and extends from the ampulla of the dorsal oesophageal gland at the base of the tooth to open on the dorsal side of the tooth just below its sharp tip. A pair of muscles extends from the dorsal surface of the oesophagus to the base of the buccal capsule and are thought to bring about jerking movements of the head. Non-specific esterase and small amounts of acid phosphatase were detected in the oesophageal glands. Non-specific esterase and cholinesterase were detected in the large amphidial glands but not in the excretory glands. The possible role of the various structures and enzymes during feeding is discussed.
