Crossover pathway
The spinoreticular tract is involved in influencing levels of consciousness and provides a pathway from the muscles, joints and skin to the reticular formationof the brainstem. The axons of the first-order neurons are localized within the spinal ganglion. They enter the spinal cord from the posterior … See more There are two spinothalamic tracts: anterior and lateral. The anterior spinothalamic tract transports course touch and pressure sensation. It is located in the anterior funiculus of the spinal cord. The lateral … See more Now that we understand the tracts involved in somatosensation, how are they integrated with movement? For example, how can our fingers follow the rim of a glass, or how can we walk in a coordinated fashion? … See more The spino-olivary tract (a.k.a. Helweg’s fasciculus) also transmits cutaneous and proprioceptive information to the cerebellum. Similar to other ascending pathways, the first … See more Now that we’ve seen the major ascending tracts of the spinal cord, we can move on to the last three minor ones. The spinotectal tract, spinoreticular tract, and the spino-olivary tract. The spinotectal tract (also known as … See more WebMost sensory and motor pathways in the central nervous system cross the midline. Comparing between different neuronal pathways in different species suggest that, fibers crossing is most probably a response to the development of separated parts for the body during the process of evolution.
