Astrocytes

...  of the cells. Blood Brain Barrier Astrocytes form part of the blood brain barrier. The long processes combine with the endothelial cells to make a distinction from the circulating blood and the cerebrospinal fluid found in the brain. The barricade stops the entry of large molecular substances and allows only the smaller molecules to pass through it. This way, bacteria and other harmful  ...

Blood Brain Barrier

...  blood brain barrier serves as the brain’s protection from its environment. It separates the circulating blood from the cerebrospinal fluid. The endothelial cells in tight junction create the boundary between the two fluids. They are responsible in restricting the flow of substances in the area. The projections of the Astrocytes, called the astrocytic feet or the glia limitans, surround  ...

Cerebrospinal Fluid

...  fluid is a clear fluid that bathes the brain and the spinal cord. It occupies the subarachnoid space. Literally speaking, the brain “floats” in the fluid. It reduces the friction in the area by serving as a cushion or buffer to prevent mechanical stress to your most vital organ. Production cerebrospinal fluid is the product of the choroid plexus. The modified ependymal  ...

Meninges

...  the dura mater and the pia mater. Arachnoid It is known to be the middle meninges, as it is located between pia matter and the arachnoid matter. One of the contents filling the arachnoid is the cerebrospinal fluid. Its membrane is delicate and is very similar to a fine fishnet. The arachnoid is extended all throughout the central nervous system, and put its end on the brain fissures. Dura  ...

Spinal Cord

...  left and right side. These 2 distinct channels are called the posterior median sulcus and the anterior median fissure. There are also three meninges protecting the brain, the spinal cord and the cerebrospinal fluid. The pia mater supply oxygen and blood to the cells. Most of the parts in the spinal cord are made up with gray matter, and is also encompassed by white matter. The gray matter,  ...

Ventricles Of The Brain

...  the fourth ventricle plays several roles for the function of the nervous system, one of its responsibilities is to communicate with the central canal of the spinal cord. It also aids the release of cerebrospinal fluid through the space in the subarachnoid. During this release, there are three foramina assisting in the process namely: the medial opening, the median aperture and the lateral  ...
