Your brain is one of the most important organs in the human body. This magnificent cluster of neurons and tissues contribute to the thoughts in one’s head, movement of one’s limbs, and subconscious actions like breathing to keep us alive. Nevertheless, whilst most organs share the recycled blood in our bodies, the brain, being the superior organ that it is, has its own pool of blood that protects, nourishes, and cleans it. In this essay we will explore what exactly the Blood Brain barrier is, its makeup, and function.

What is the Blood Brain Barrier? What is its makeup?

The Blood Brain Barrier or (BBB), is a protective …show more content…

Penetration of the Blood Brain Barrier.

There are multiple limitations of penetration in the BBB. There are very minimal movement of the materials from the systemic circulation to the brain, which buffer in the brain changes rapid ionic or metabolic conditions.

Why is the movement of the Blood Brain Barrier So Limited? The limited BBB penetration also protects the brain from exposure to molecules that are harmless to peripheral organs, but toxic neurons in the brain. BBB penetration affects neurons, extracellular matrix, and non-neuronal cells, including astrocytes, pericytes, and vascular endothelial cells. These cells along with an extracellular matrix, function as a neuro-unit unit to regulate BBB permeability and maintain integrity and function on the central nervous system.

In conclusion The Blood Brain Barrier is extremely essential to ensuring our survival and protecting our sensitive brain. The chemical composition of the BBB helps maintain a suitable environment for the brain allowing it to thrive and remain protected in its own juices. Should anything happen to ones BBB, they can experience some horrendous consequences.

The Pros And Cons Of Blood Brain Barrier

139 Words | 1 Pages

The blood brain barrier’s main goal is to protect the brain from toxic agents. By doing this, it can interrupt or block the delivery of therapeutic drugs to our brain. Many trials have been attempted to try and force the transport of drugs across the BBB, but some of these ways can structurally damage the BBB. The ideal goal would be to find a way to control the transport drugs across the barrier, but not damaging it at the same time. The most ideal approach found for this goal was “nanobiotechnology-based” delivery.

Neuroinflammation is an altered situation developed in the presence of plays a significant role in various chronic and acute pathological conditions of the central nervous system. Our results showed that the stimulation of C6 cells with LPS (0.5 μg/mL) significantly increased the level of TNF-α and IL-6 in culture supernatant when compared with unstimulated cells (Fig. 3). It is well established that glial cells are the resident innate immune cells of the central nervous system, plays a critical role in inflammation-mediated neurodegeneration disorders. Lipopolysaccharide (LPS), an endotoxin, the outer membrane component of Gram-negative bacteria, is a major pathogenic factor in sepsis.

Cerebrovascular Attack Case Study

A Cerebrovascular accident, a brain attack, or more commonly known as a Stroke, is the most common disabling neurological disorder (Aminoff, Greenberg and Simon, 2015), which affects 1.8% of the Australian population, this is an estimated 264,900 people(Abs.gov.au, 2015) . The World Health Organisation (World Health Organisation, 2015) states that a stroke is an “interruption of the blood supply to the brain, usually because a blood vessel bursts or is blocked by a clot. This cuts off the supply of oxygen and nutrients, causing damage to the brain tissue”, which can result in lasting brain damage, long-term disability, or even death. What makes a stroke so unique, is that the outcome of a stroke is different for every person. This essay

Brain Aneurysm Four major blood vessel supply blood to the brain. They join together at the circle of willis at the base of the brain. Smaller arteries leave the circle and branch out to supply brain cells with oxygen and nutrients. Artery junction points may become weak causing a ballooning of the blood vessel wall to potentially form a small sac or aneurysm. Cerebral aneurysms are common but most are asymptomatic and are found incidentally at autopsy.

A hemorrhagic stroke is caused when an artery is ruptured or leaks blood in the brain (National Center for Chronic Disease Prevention and Health Promotion, Division for Heart Disease and Stroke Prevention, Types of Stroke (2013). Another form of strokes are Transient Ischemic Attacks (TIAs) often referred to as “mini strokes” (AHA/ASA, 2012). These are often warning signs that a stroke could occur if an individual’s lifestyle or risk factors are not modified. During a TIA, there is a temporary decrease in blood supply to the brain; symptoms usually last less than 24 hours before disappearing (NSA, 2012). Epidemiology Fifteen million people suffer stroke worldwide each year (World Health Report, 2002).
