A friend injures their ankle so you ask how they got hurt. They tell you they stepped off a curb and rolled it. As you think about the mechanisms for how this injury would occur, you piece together your knowledge of corpuscles, proprioceptors and actions of muscles to understand what happened. As the student stepped off the curb, their ankle rolled into plantarflexion and inversion. The corpuscle that would have sensed this dangerous change in joint position is the corpuscle. At the same time, another proprioceptor that is sensitive to stretch and rate of stretch, the , would have been stimulated in the muscles in the lower leg that are responsible for plantarflexion and eversion. These muscles are the . The nervous system would simultaneously send information from the receptors around the ankle to the CNS via an neuron. The CNS would then send information back to the receptors via an neuron to stimulate a corrective movement.
