Lymphatic Nodes
Lymphatic nodes are categorized into several groups:
- Parotid lymph nodes: Receive lymph from the side of the face and scalp
- Submandibular lymph nodes: Get lymph from the upper lip and part of the lower lip as well as most of the oral cavity
- Submental lymph nodes: Get lymph from the chin and centre of the lower lip
Lymph from these nodes eventually drains into the deep cervical lymph nodes. The deep cervical lymph nodes drain into the jugular lymphatic trunk, which joins the internal jugular vein or brachiocephalic vein on the right side and thoracic duct on the left side.
