I want to focus now on the ascending sensory pathways within the dorsal funiculus, called the dorsal column system . In the case of the dorsal column system, these axons are called alpha-beta fibers.
Pacinian corpuscles are velocity detectors and sense vibration .
The above three receptors lie in the skin and can account for two point discrimination and vibration . Ruffini corpuscles within joint capsules might convey such information.
