WebIn neuroanatomy, the corticobulbar (or corticonuclear) tract is a two-neuron white matter motor pathway connecting the motor cortex in the cerebral cortex to the medullary pyramids, which are part of the brainstem 's medulla oblongata (also called "bulbar") region, and are primarily involved in carrying the motor function of the non-oculomotor ... WebThe following pathway is sectioned in a chordotomy for the treatment of pain: A. Lateral spinothalamic tract This answer is CORRECT! From the above nerve fibers, only the lateral spinothalamic tract carries pain sensation, and sections of these fibers will prevent pain information from getting to the brain. B. Ipsilateral dorsal column

They are the anterior and lateral spinothalamic tracts (STT): Anterior STT: crude touch and pressure. Lateral STT: pain and temperature. The pathway of the spinothalamic tracts is shown in the table 2.

WebThe spinothalamic tract is a collection of neurons that carries information to the brain about pain, temperature, itch, and general or light touch sensations. The pathway starts with sensory neurons that synapse in the dorsal horn of the spinal cord. Next, neurons extend from the dorsal horn and decussate, or cross over to the other side of the ...
