Detailed explanation-1: -The ascending tracts include the dorsal column-medial lemniscus system, the spinothalamic system, and the spinocerebellar system. These tracts carry sensory information from the periphery, such as pain, touch, and temperature to the brain.
Detailed explanation-2: -The corticospinal tract belongs to one of the most important descending tracts of the CNS. It contains fibers from the upper motor neurons to synapse on the lower motor neurons.
Detailed explanation-3: -Ascending tracts (Figure 3.8). The nerve fibers comprise the ascending tract emerge from the first order (1°) neuron located in the dorsal root ganglion (DRG). The ascending tracts transmit sensory information from the sensory receptors to higher levels of the CNS.
