The philtrum is the vertical groove between the base of the nose and the upper lip.

The nasolabial sulcus is the crease that runs from the corner of the nose to the corner of the mouth.

Lymph draining from the upper lip and lateral parts of the lower lip usually flows to the submandibular lymph nodes.

Lymph draining from the medial part of the lower lip first flows to the submental lymph nodes.

The transitional zone between the philtrum and the nasolabial sulcus.
