motor nucleus of V
Term
Pain and sensation: does input cross over to the contralateral side? if so which fibers going to where?
Definition
spinal trigeminal nucleus fibers cross to join the ventral trigeminal thalamic tract
Term
Tactile sensation: does input cross over to the contralateral side? if so which fibers going to where?
Definition
yes and no. fibers of chief sensory nucleus go to contralateral VTTT and DTTT as well as ipsilateral DTTT
Term
Proprioception: does input cross over to the contralateral side? if so which fibers going to where?
Definition
no, they remain ipsilateral
