What type of information does the dorsal root send to the central nervous system?

The dorsal root of the spinal cord is responsible for transmitting sensory information to the central nervous system (CNS). It contains sensory nerve fibers that carry signals from peripheral sensory receptors to the spinal cord and, subsequently, to the brain. This type of information includes sensations such as touch, pain, temperature, and proprioception, which are critical for the body's awareness of its environment and internal state.

The dorsal root is integral in processing sensory input, allowing the CNS to react appropriately to various stimuli. Understanding this function is essential for physical therapy, as many therapeutic interventions may depend on the accurate transmission of sensory information to assess and treat conditions effectively. The other options relate to different components of neural pathways or functions that are not directly associated with the dorsal root.
