Upper motor neuronsGroup of answer choicescontrol the upper half of the torso.synapse on muscles in the eye, neck, and head.synapse on local circuit neurons and/or lower motor neurons.affect motor patterns only indirectly via their inputs to the basal ganglia.have cell bodies that are located in the ventral horn of the spinal cord.

Which statement best describes fast-twitch muscle fibers?Multiple Choicemotor unit contains many fibers that are designed for strength and working under anaerobic conditionsmotor units that contain many fibers are are designed for endurance and working under anaerobic conditionsmotor units with few muscle fibers that are useful for endurance activitiesdark in color, contain large numbers of mitochondria and good for strength
