Our previous studies confirmed that the central pathway of trigeminal proprioceptive sensation consists of four orders of neurons , and neurons from the first - to the fourth - order are located , respectively , in the mesencephalic trigeminal nucleus ( vme ) , the dorsomedial part of the subnucleus oralis of the spinal trigeminal nucleus and its adjacent reticular formation ( vodm - lrf ) , the " zone - shaped area " [ including the caudolateral part of the supratrigeminal nucleus ( vsup - cl ) , the dorsomedial part of the principal sensory trigeminal nucleus ( vpdm ) , the area ventral to the motor trigeminal nucleus ( avm ) and the area dorsal to the superior olivary nucleus ( ado ) ] and the contralateral ventral posteromedial nucleus ( vpm ) of the thalamus . because the pathway is a novel one , there has been little systematic morphological data available so far regarding the neurotransmitters involved in this pathway 該通路中第二、三級神經(jīng)元所在地分別是三叉神經(jīng)脊束核吻側(cè)亞核背內(nèi)側(cè)區(qū)及其鄰接的網(wǎng)狀結(jié)構(gòu)( dorsomedialpartofthesubnucleusoralisofthespinaltrigeminalnucleusanditsadjacentreticularformation , vodm - lrf )和帶狀區(qū)[包括背側(cè)的三叉上核尾外側(cè)部( caudolateralpartofthesupratrigeminalnucleus , vsup - cl )和感覺主核背內(nèi)側(cè)部( dorsomedialpartoftheprincipalsensorytrigeminalnucleus , vpdm )及腹側(cè)的兩個分別位于三叉神經(jīng)運動核腹側(cè)和上橄欖核背側(cè)的暫命名為avm ( areaventraltothemotortrigeminalnucleus )和ado ( areadorsaltothesuperiorolivarynucleus )的兩個小核團(tuán)] 。
百科解釋
The spinal trigeminal nucleus is a nucleus in the medulla that receives information about deep/crude touch, pain, and temperature from the ipsilateral face. The facial (cranial nerve 7), glossopharyngeal (CN9), and vagus nerves (CN10) also convey pain information from their areas to the spinal trigeminal nucleus.
