THE LYMPHATICS OF THE TONGUE

Abstract
The lymphatic apparatus in dogs'' tongues has been studied in a state of lymphatic stasis provoked by the ligation of the cervical lymph trunks and nodes. Lymph vessels with separate walls exist only in the connective tissue (perimysium and tunica propria). The lymphatic supply of the tongue is not uniform over its whole area. The number of lymph vessels diminishes from tip to root. Lymph vessels may be independent of blood vessels (e. g. in the tunica propria) or may run in the perivascular connective tissue (perimysium), while the larger trunks on the under surface of the tongue follow the course of the arteria profunda linguae and its branches. Except in the perimysium, there are no lymph vessels with separate walls in the lingual musculature.
