Quizplus · Accepted Answer

Central awareness of muscle stretch primarily involves the stimulation of muscle spindles, which are innervated by γ (gamma) motoneurons. These neurons adjust the sensitivity of muscle spindles to stretch, thereby playing a crucial role in proprioception and the central nervous system's awareness of muscle stretch. α (alpha) motoneurons, on the other hand, are responsible for the contraction of muscle fibers and do not directly contribute to the sensation of muscle stretch.
