 | | The medial lemniscus may be considered as the upward continuation of the posterior funiculus of the spinal cord and to convey conscious impulses of muscle sense and tactile discrimination. | | | The greater part of the medial lemniscus, on the other hand, is prolonged through the tegmentum, and most of its fibers end in the thalamus; probably some are continued directly through the occipital part of the internal capsule to the cerebral cortex. | | | Fibers are said to pass through the medial longitudinal fasciculus from the nucleus of the abducent nerve into the oculomotor nerve of the opposite side, and through this nerve to the Rectus medialis oculi. |

| | BASIC SOMATOSENSORY PATHWAY |
| | Once the pathways synapse in the brainstem, they join the pathways from the body on their way up to the thalamus. | | | The motor pathways are pathways which originate in the brain or brainstem and descend down the spinal cord to control the a-motor neurons. | | | The pathway is as follows: the vestibular nerve enters the brainstem and synapses in the vestibular nucleus. |

| | Spinothalamic tract - Wikipedia, the free encyclopedia |
| | The spinothalamic tract is the sensory pathway in the body that transmits pain, temperature, itch and crude touch. | | | These types of sensation cross over to the other side of the body at the spinal cord, not in the brainstem like the posterior column-medial lemniscus pathway and corticospinal tract. | | | The name spinothalamic tells us sensation runs up the spinal cord to the thalamus; this is true but misleading, as all sensory pathways synapse at the thalamus. |
