Organ
Pericervical lymph node ring
Regional nodal groups around the head-neck junction
High-yield
Posterior scalp lymph commonly reaches occipital nodes, while preauricular/parotid nodes receive parts of the lateral face, eyelids and ear. Adjacent territories overlap.
Overview
Several node groups form a loose collar around the transition from head to neck. Occipital, mastoid, parotid, facial, submandibular and submental groups collect lymph from different superficial territories. This is a regional arrangement, not a continuous anatomical ring.
Reference facts
- Location
- Around the scalp base, ears, cheek and lower jaw, continuing toward cervical collecting pathways.
- Parts
- Occipital, mastoid/postauricular, parotid/preauricular, facial, submandibular and submental groups; superficial cervical nodes form an associated neck pathway.
- Drains from
- Regional scalp, auricular, external ear canal, eyelid, facial and superficial neck tissues.
- Venous/Lymphatic drainage
- Efferents reach cervical collecting chains, directly or through additional regional nodes; routes vary by group.
- Function
- Filters lymph and coordinates immune surveillance from the superficial head and adjacent neck.
Clinical correlation
A node's location can guide examination of nearby skin, scalp, eye or ear disease. Enlargement alone does not pinpoint the cause: inflammatory, infectious and malignant processes can share the same nodal territory.
Frequently asked questions
Where is the pericervical lymph node ring located?
The pericervical lymph node ring lies around the scalp base, ears, cheek and lower jaw, continuing toward cervical collecting pathways.
What does the pericervical lymph node ring do?
Filters lymph and coordinates immune surveillance from the superficial head and adjacent neck.
What are the parts of the pericervical lymph node ring?
Occipital, mastoid/postauricular, parotid/preauricular, facial, submandibular and submental groups; superficial cervical nodes form an associated neck pathway.
How does the pericervical lymph node ring drain?
Efferents reach cervical collecting chains, directly or through additional regional nodes; routes vary by group.
