Ascending Tracts

The ascending fiber tracts convey sensory information from cutaneous receptors, proprioceptors (muscle and joint receptors), and visceral receptors (table 8.4). Most of the sensory information that originates in the right side of the body crosses over to eventually reach the region on the left side of the brain that analyzes this information. Similarly, the information arising in the left side of the body is ultimately analyzed by the right side of the brain. For some sensory modalities, this decussation occurs in the medulla oblongata (fig. 8.20); for others, it occurs in the spinal cord. These neural pathways are discussed in more detail in chapter 10.
