Describe the function of the brain ventricles. Your Answer: Brain ventricles ARE 4 and are found inside the brain and filled with CSF. 2 laterals and 3rd and 4th ventricles all of them drain in the central canal of the spinal cord and contains CSF; their main function it is where the CSF is made which helps to absorb impacts when the brain faces them for any activity or movements
There are four ventricles in the interior of the brain, chambers filled with cerebrospinal fluid which is produced there. Once formed the CSF circulates through the ventricles and into the subarachnoid space bathing and floating the brain.

What is muscle tone and how is it maintained? Your Answer: It is manage by the sensory muscles spindles which work with the stretching of the muscles; it helps to maintain muscles contraction. It is crucial for creating reflexes help with the postures and the equilibrium Correct answer Muscle tone is the degree at which muscles remain partially contracted while at rest. Muscle tone is continuously monitored and maintained by the cerebellum to keep bones and joints in place. Question 9
