Trigeminal thalamic pathway
WebThe first-order nociceptive neurons from the head, face and intraoral structures have somata in the trigeminal ganglion (Figure 7.2). Trigeminal fibers enter the pons, descend to the medulla and make synaptic connections in the spinal trigeminal nucleus, cross the midline and ascend as trigeminothalamic tract (or trigeminal lemniscus, Figure 7.2). WebJul 1, 2024 · The principal (PN) and spinal (SN) trigeminal nuclei, in charge of tact and pain respectively, project to the thalamus via three main pathways: the ventral trigemino …
