This preview shows page 1 - 5 out of 37 pages.

Trigeminal Sensory PathwaysSensory Systems IITrace sensory input from the three branches of the trigeminal nerve back throughthe trigeminal ganglion to the brainstem.Map the course of the trigeminal nerve in the brainstem including the: centralprocesses of the trigeminal nerve, chief sensory nucleus, trigeminal motornucleus, mesencephalic trigeminal nucleus, spinal trigeminal nucleus.Describe the somatotopic organization within the Trigeminal Nuclear Complex(TNC)Identify cranial nerves other than V that project sensory axons to the chief sensorynucleus and the spinal trigeminal nucleus.Describe the pathway followed by sensory information from the trigeminal nucleito the thalamus and then to the somatosensory cortex.Map the course of proprioception from the oral cavity and a muscle of masticationto the Trigeminal Sensory NuclearComplex and to the Motor Nucleus of V.Discuss the mechanisms involved in central sensitization including the neuralstructures responsible for maintenance of persistent pain.
