Trigeminal pahway 1

This video describes the pathway of general sensation from face.
- 3 divisions of trigeminal nerve (ophthalmic/V1, Maxillary/V2 and mandibular/v3) carry general sensation from face and pass through trigeminal ganglion. the first order neuron stop in trigeminal nerve sensory nuclei that extend through the length of brain stem:
- Pain and temperature stop in spinal trigeminal nucleus/Medulla
- touch stops in principal nucleus/Pons
- Proprioception from tempromandibular joint carried by V3 and ends in mesencephalic nucleus/midbrain
- Second order neuron arises from these nuclei and cross to the opposite side to ascend in brainstem as trigeminothalmic tract/trigeminal lemniscus that ends in the ventroposteromedial nucleus of thalamus (VPM).
-3rd order neuron, arises from thalamus and ends in the lower part of sensory area (postcentral gyrus)
*Injury of Trigeminal lemniscus/trigeminothalamic tract causes contralateral loss of facial sensation
*Trigeminal neuralgia is sever kind of intermittent pain that triggered by touch (brushing teeth, shaving or applying make-up). more common in female. One common cause is aneurysm of superior cerebellar artery. Trigeminal neuralgia can be treated by microvascular decompreession of the ganglion, anti-convulsant such as tegretol and gamm knife.

If it had been audible, would hv been the best

Thanks. But sorry, it's painful, especially your tiping

Thank you Emil. I agree, do you have an idea how to get rid of the typing sound?

@@EasyAnatomy Sorry, but I don't know your device. Typing on my computer is completely silent.
But anyway, your work is great, thank you
