WebIn some experiments, slowly conducting fibers ( Aδ and/or C ) were found to provide most or all of the excitatory drive to neurons of the dorsal horn's marginal zone (Rexed's lamina I) in a cat. A similar set of experiments in a monkey provides additional information on the excitatory projection of afferent units with fine fibers. A type Ia sensory fiber, or a primary afferent fiber is a type of afferent nerve fiber. It is the sensory fiber of a stretch receptor called the muscle spindle found in muscles, which constantly monitors the rate at which a muscle stretch changes. The information carried by type Ia fibers contributes to the sense of proprioception.
