Question
Chapter 5.2, Problem 3CYU
Summary Introduction
To write:
The reason by which the blood-brain barrier limits the transport through the cells of the brain capillaries wall.
Introduction:
Blood-brain barrier can be defined as a semipermeable membrane that separates the blood from the cerebrospinal fluid. It provides a barrier to the channel of particles, cells, and large size molecules.

The middle cerebellar peduncles connect the pons to the cerebellum and carry efferent information from the cerebral cortex and the pontine nuclei into the cerebellum. b. In all cases, damage in one hemisphere of the cerebellum (left or right) affects that same side of the body c. This retention of learned motor skills is called motor memory which is mastermind by the Cerebellum d. The cerebellum has three (3) regions: an outer cortex of gray matter, internal white matter called the arbor vitae ("tree of life"), and deeply situated gray matter called deep cerebellar nuclei.

EXPLANATION ADDRESSING THE QUESTION ABOVE Cerebral spinal fluid is a fluid that cushions the central nervous system and provides buoyancy to and helps nourish the brain. It circulates around the surface of the brain, interior ventricles, and surface of the spinal cord and central canal of the spinal cord. CSF is created by the ependymal cells in the choroid plexus and ventricles of the brain. CSF is made up mostly of water and also includes ions, nutrients like vitamin c and protein, and can pick up waste as it circulates. CSF circulation starts in the lateral ventricle where the choroid plexus and lateral ventricle creates or secretes the CSF. The CSF then flows through the ventricular foramen into the third ventricle. At the third ventricle, the CSF then flows through the cerebral aqueduct into the fourth ventricle. Then, the CSF exits the fourth…arrow_forward
