A pair of poison glands
A paired sac-like poison glands are situated on the entire sides of the upper jaw. The poison gland is modified into salivary gland, from the anterior part of the gland a thin poison duct comes out, which comes ahead through the lateral part of the upper jaw and from a loop above the fangs.
The glands may be small and oval (sea snakes) or large and tubular (vipers) depending on species. Ligaments help in the position of poison gland. Anterior ligament attaches anterior end of the gland with maxilla and the posterior ligament runs between the gland and quad-rate.
Poison Ducts of Snakes
A narrow poison duct come anterior from each poison gland to the base of a poison fang to enter its groove or canal.
