What is the Trigeminocervical nucleus?
What is the Trigeminocervical nucleus?
The trigeminocervical nucleus is a region of the upper cervical spinal cord where sensory nerve fibers in the descending tract of the trigeminal nerve (trigeminal nucleus caudalis) are believed to interact with sensory fibers from the upper cervical roots.
Where is the Trigeminocervical nucleus located?
lower brainstem
The trigeminocervical nucleus is an area in the lower brainstem (in the skull not far above the top of the neck), that receives information from areas that the trigeminal nerve supplies (see diagram) and also receives information from the top three spinal nerves of the neck (spinal nerves of C1, C2 and C3).
What is the Trigeminocervical complex?
The convergent inputs to the central projection of the trigeminovascular system, the trigeminal nucleus caudalis and the C1 and C2 regions of the spinal cord, collectively known as the trigeminocervical complex (TCC) is thought to explain the common distribution of pain in migraine.
Where is the mesencephalic nucleus located?
midbrain
The mesencephalic nucleus is a paired structure located at the mesopontine junction which projects cephalad through the midbrain. It is situated along the anterolateral aspect of the periaqueductal grey matter and lies ventral to the inferior colliculi at the level of the midbrain.
Why does my neck ache and I have a headache?
If you’re tense, muscles in your neck, scalp, shoulders, and jaw can tighten up. That can lead to a tension headache. Depression or anxiety can also cause the same symptoms. Try to eat well and get enough rest.
What is the Trigeminovascular pathway?
The trigeminovascular system is the major pain-signalling pathway of the visceral organ brain (Moskowitz 1984), but there is still no definite proof that an activation of its peripheral components is necessary to produce a migraine attack.
What is mesencephalic nucleus?
The mesencephalic nucleus is a paired structure located at the mesopontine junction which projects cephalad through the midbrain. It is situated along the anterolateral aspect of the periaqueductal grey matter and lies ventral to the inferior colliculi at the level of the midbrain.
Can neck problems affect your eyes?
Tension in the neck and shoulders can lead to eye strain, as tense muscles can press on eye nerves at the back of your neck.
