Activation of musculature primarily in the arms and legs and partly in the trunk and neck.

Cerebro-Pontocerebellum, in collaboration with cortex cerebralis as well as tractus cortico-nuclearis and tractus cortico-spinalis, affects motor skills in an intricate and refined way. It is about the preparation and temporal coordination of different individual muscles and muscle groups, which must be activated at a certain moment during a succession of complicated movements. It is mainly about extremity motor skills, mimicry motor skills and speech motor skills.
