Functions of salivary glands during tick feeding are discussed. The salivary glands secrete various components essential for attachment to the host and feeding. Among them cement precursors, enzymes and inhibitors, anti-coagulants, prostaglandins, histamine antagonists and agonists, and toxins are of great importance in these processes. The salivary glands are also involved in the excrete of water during feeding, in the regulation of ionic composition of the haemolymph, and in transmission of pathogens.
