Question
Chapter 15, Problem 13CP
Summary Introduction
To determine:
The effects on the muscle tone when there is an increase in the stimulation of the motor neurons of the red nucleus.
Introduction:
The stimulus in the red nucleus is responsible for the facilitation of the contralateral motor neurons which supply flexor muscles inhibition of contralateral motor neurons supplying extensor muscles.
