What Is the Path of the Cerebrospinal Fluid from Its Formation Site

The brain is a soft, delicate, non-replaceable and spongy mass of tissue. Brain is considered as a kernel part of the body and has a very complex structure. The brain consists of mainly two types of tissues: gray matter (GM) and white matter (WM). The brain also contains a cerebrospinal fluid (CSF) that consists of enzymes, glucose, salts, and white blood cells. The brain is divided into three major parts, the hindbrain (including the cerebellum and the brain stem), the midbrain, and the forebrain (including the diencephalon and the cerebrum).The body is made up of many

Cerebrovascular accidents, or strokes, will lead to brain damage that affects the functioning of executive function, memory, language, visuospatial performance and emotional states. Corresponding vertebral arteries and carotid arteries provide blood to the brain from the heart that the carotid arteries are internal and external sections of the thyroid cartilage. Where the optic nerve rests the internal artery distributes into the anterior and middle cerebral arteries. The vertebral arteries arise through the spinal vertebrae and meet the lower pons to form the basilar artery. The brain receives 15% to 20% of the oxygenated blood from the heart and can only endure fleeting interruptions of blood flow before neural operations

a small amount of spinal fluid can be then removed and tested to determine if there is some type of infection or other underlying medical problems. Lumbar Puncture can also be used to measure the pressure of the spinal canal and measure the brain. Research has shown that the cell membrane that surrounds every neuron has an important role in Epilepsy, these membranes are responsible for the neurons to generate an electrical impulse and for some reason when the brain attempts to repair itself after head trauma, stroke, or another problem that may generate atypical nerve connections that will lead to Epilepsy. Studies in animals have also provided that because the brain constantly adapts to changes in a small change in neurological activity, if repeated this may increase the chances of a full blown epileptic attack. Anomalies in the brain connections that happen while the brain develops may also disrupt neurological activity which could lead to Epilepsy. Research has also shown that the repeated attacks of the temporal lobe can cause the hippocampus to shrink, the hippocampus is responsible for learning and memorization, but it may however take years for such a seizure attack to do significant

When inflammation occurs, the barrier becomes more permeable. The bacteria invade the respiratory passages and are disseminated by the bloodstream to the cerebrospinal fluid (CSF) space and the meninges of the brain and spinal cord. A gathering of fluid damages the cranial nerves, destroys cerebral spinal fluid pathways, and induces vein

Correspondingly, there are two pathways that transports blood to the brain called internal carotid artery and vertebral artery. The internal carotid artery has three layers call the tunica adventitia, tunica media, and tunica intima. Tunica intima is made up of smooth muscle cells and elastin. The basilar artery forms and it branches out to the posterior cerebral arteries. The posterior cerebral arteries form the internal carotid arteries and when they connect they make cerebral arterial circle ( circle of willis). The middle cerebral arteries branch out two separate arteries called the anterior cerebral arteries. Each of these arteries are the force that direct the blood flow to the brain. There are three tiny vascular systems that work together to profuse the deep brain. Which are the pial, subependymal, and lenticulostriate arteries. The small area of white matter that depends on blood flow is called the subcortical “shed water” area. The subcortical is more prone than other areas of the brain to have ischemia. The leading cause of ischemia is the fibrin builds up and this cause a narrowing of the lumen. Which does not allow the flow of red blood cells and deprives the white matter of tissue of oxygen. The tissue then losses density and produces white matter lesions. The neurons become demyelinated which leads to loss of cognitive ability.

Beginning with the three main parts of the brain, the brain stem, the cerebellum, and the cerebrum, the website gives an overview of what I had studied in Basic Anatomy and Physiology class. The cerebrum, which controls memory, thinking, emotions, and voluntary movement, is the primary part of the brain affected by AD. In order to carry out its functions, the brain requires a rich blood supply of about 20 to 25 percent of the bodies’ blood total with each heartbeat. The whole vessel network picture demonstrates how vast the blood supply to the brain is and makes it understandable that up to 50 percent

The cerebrum is situated at the back of the brain. The cerebrum is divided into two cerebral hemispheres, left and right. It consists of the corpus, callosm, and nerve fibers. The left and right hemispheres communicate with each other. The brain stem “connects the brain to the spinal cord” (Lu & Bludua, 2011), which regulates the body. The cerebellum is positioned beneath the cerebrum. It manages a person’s equilibrium and coordination.

The three main tissues that support and protect the CNS are commonly known as the meninges. They protect by preventing direct circulation of blood through the cells of the brain and spinal cord. These layers have elasticity within the tissues coating the CNS. In order the layers are the dura mater, the arachnoid layer, and pia mater. The last two layers have cerebrospinal fluid within which acts as a shock absorber to the brain. The cerebrospinal fluid transports hormones, white blood cells and nutrients to the cells of the

• Is an enlargement of a small channel that allows fluid to flow through the upper and lower areas of the brain and spinal cord (fourth ventricle).

The fluid in the brain (cerebrospinal fluid or CSF) is formed in the brain. CSF usually circulates through parts of the brain, its covering, and the spinal canal, and is then absorbed into the circulatory system.

     Tight junctions seal together the enclothelial cells of brain capillaries, which also are surrounded by a thick basement membrain. The process of many astrocyties pressing up against the capillaries is known as the Astrocyties Process. This process selectively passes some substances from the blood to the neurons, at the same time, inhibiting the passage of others.

That layer of cells forms a barrier between the capillaries and the cells and fluid of the brain.
