Motor pathways of trigeminal
NettetStructure. The nucleus is situated in the caudal portion of the ventrolateral pontine tegmentum.Its axons take an unusual course, traveling dorsally and looping around the abducens nucleus, then traveling ventrally to exit the ventral pons medial to the spinal trigeminal nucleus.These axons form the motor component of the facial nerve, with …

NettetThe trigeminal mesencephalic nucleus (MesV), located at the mesopontine junction, is a unique sensory structure. It contains cell bodies of primary afferent proprioceptors, Ia afferents, that innervate the jaw-closing muscles (masseter, temporalis and medial pterygoid) and the periodontium.
