The Trigeminocervical Nucleus
When someone presents with headache, jaw pain, neck pain, dizziness, or even facial symptoms, it’s easy to treat the area that hurts. But the body rarely works in isolation.
One key player worth thinking about is the trigeminocervical nucleus.
This structure in the brainstem receives sensory input from both the trigeminal nerve (face and jaw) and the upper cervical spine (C1–C3). Because of this convergence, pain from the neck can be felt in the head or face, and facial symptoms can be influenced by the cervical spine.
So when assessing a patient with for example:
• headache
• migraine-like symptoms
• jaw pain
• facial pain
• upper neck stiffness
…it raises an important question:
Are we treating the symptom, or are we investigating the system?
Critical thinking in manual therapy means looking beyond the obvious. It means considering neural convergence, shared pathways, and the interaction between the cervical spine and craniofacial structures.
Understanding the trigeminocervical nucleus reminds us that good manual therapy isn’t just about technique.
It’s about clinical reasoning.
