The spinal tract refers to the pathways in the spinal cord that carry signals between the brain and the rest of the body. These tracts are essential for transmitting sensory information, such as touch and pain, as well as motor commands that control movement. There are two main types of spinal tracts: ascending tracts, which send sensory information to the brain, and descending tracts, which relay motor commands from the brain to the body. Proper functioning of these tracts is crucial for coordination and response to stimuli.
