The Telencephalon is the largest portion of the brain. This portion of the brain is in charge of voluntary movements‚ sensory input‚ and complex cognitive process (learning‚ speaking‚ and problem solving skills). The Diencephalon is composed of two structures‚ the thalamus and the hypothalamus. The thalamus holds

Astrocytes help form the blood brain barrier. The blood brain barrier prevents harmful materials from moving out of the bloodstream and into the brain. It helps maintain an ion gradient and is important in the transport of materials into and out of the brain. Its endothelial cells contain many tight and adherens junctions‚ which make the endothelial cells of these capillaries tighter than in other places in the body. Astrocyte feet are in physical contact with the capillary endothelial cells. In
