Answer: Brain ventricles: these are the cerebrospinal fluid filled spaces mainly present within the brain useful to protect brain from shocks. Over the ages mainly from Anno domino 130 to 200, scientist and Greek physician, Galen have illustrated about these hollow and fluid filled spaces. According to him, brain ventricles are going to function for a balance of cerebrospinal fluids and sensation and humors associated with movements are mediated by these brain ventricles within the brain through cranial nerves. According to Galen, these ventricles are mainly involved in registering sensations and perceptions finally to promote motor activity through limb movements. French scientists have illustrated that these ventricles are mainly enabled fluid- mechanical theory of brain function to mediate limb movements via muscle activity..

Solution
Ques-1: What are brain ventricles, and what functions have been ascribed to them over the ages?
Answer:
Brain ventricles: these are the cerebrospinal fluid filled spaces mainly present within the brain
useful to protect brain from shocks. Over the ages mainly from Anno domino 130 to 200,
scientist and Greek physician, Galen have illustrated about these hollow and fluid filled spaces.
According to him, brain ventricles are going to function for a balance of cerebrospinal fluids and
sensation and humors associated with movements are mediated by these brain ventricles within
the brain through cranial nerves. According to Galen, these ventricles are mainly involved in
registering sensations and perceptions finally to promote motor activity through limb
movements. French scientists have illustrated that these ventricles are mainly enabled fluid-
mechanical theory of brain function to mediate limb movements via muscle activity.
