Spinal thalamic tract
WebThe ventral trigeminal tract, ventral trigeminothalamic tract, anterior trigeminal tract, or anterior trigeminothalamic tract, is a tract composed of second order neuronal axons. These fibers carry sensory information about discriminative and crude touch, conscious proprioception, pain, and temperature from the head, face, and oral cavity. WebThe two major pathways of nociceptive information are the spinothalamic tract and the spinoreticular tract. The cell origin of the spinothalamic tract is in the dorsal horn and intermediate gray matter of the spinal cord. Axons of these neurons cross to the anterolateral quadrant and ascend to the thalamus, where they synapse on neurons in the ...
