labial gland

Salivary secretions from the labial glands dilute the ingested food.

Another method of species identification is to compare the labial gland secretions across other taxa and examine them for any chemical differences.

These react with a secretion from the labial gland upon autothysis to form a mixture which is toxic to other termites.

The mucous salivary glands are similar in structure to the buccal and labial glands.

The superior labial branches descend behind the Quadratus labii superioris, and are distributed to the skin of the upper lip, the mucous membrane of the mouth, and labial glands.

The goal was to establish a 95% similarity in male labial gland secretions among the species recovered; if they could do so, it was inferred that there wasn't enough difference to accurately establish a difference in species.

It supplies the labial glands, the mucous membrane, and the muscles of the lower lip; and anastomoses with the artery of the opposite side, and with the mental branch of the inferior alveolar artery.

Like the parotid and buccal glands, the labial glands are innervated by parasympathetic fibres that arise in the inferior salivatory nucleus, travel with the glossopharyngeal nerve and lesser petrosal nerve to the otic ganglion, where they synapse and then continue to the labial glands.
