White MatterGray matter is peculiar for containing the neuron cell bodies. In this article, we will discuss the nature of these two types of structures, their differences, significance, and functions.Finally, we will address different conditions, diseases, and damages of the white and the gray matter, as well as its consequences. The present study was designed to investigate the brain structural and emotional changes after peripheral local infection initiated chronic systemic inflammation and the relationship between circulating inflammatory markers and brain grey matter.Despite this, scientists have managed to discover a lot about this mysterious organ that is the node of our personality and life.Into lobes, the left, and right hemisphere, and brain parts help us understandIts structure and, more importantly, its functions and mechanisms in a betterVery common and meaningful classification of the brain structures refers to the gray and white matter diversification. The white matter of your brain and spinal cord is composed of bundles of.
They exist in both brain and spinal cord, we must emphasize one detail. This structure connects the brain cells and is distributed in tracts or bundles.Even though both types of matter are arranged throughout our CNS, i.e. As their color is whiteish, these structures are called the white matter.The color comes from a high lipid fat content in myelin. They extend out from the neuron bodies. These structures are long relays.
Moreover, as expected, the brain part which loses the largest portion of neurons dictates the progression of the disease. Unfortunately, millions of people worldwide suffer from these neurodegenerative diseases.Even though changes in the white matter are also found in these diseases, scientists point out that tau neurofibrillary tangles and amyloid plaques are located in the gray matter.That's why these diseases are most commonly linked to the changes in the gray matter found in different brain structures. Those include frontotemporal dementia and Alzheimer's disease. Content of gray and white matterGray matter damages and diseases cause significant dysfunctions of different systems, primarily the difficulties in interpreting the sensory information, as well as the motor information receipt system.As a result, patients suffer from paralysis, muscle weakness, as well as tingling sensations.When it comes to the origin of these diseases, they are classified as neurodegenerative diseases. Therefore, things are not very black-and-white (or gray-and-white), nor simple. Such types exist both in white and gray matter.
The spinal cord are damaged, the link between the gray matter in the spinal cord and brain is either jeopardized or completely lost.As a result, the patient can suffer from sensory issues, paralysis, and other dysfunctions which can be permanent if there is damage to the neuronal body. If the axon bundles found in this part of the nervous system, i.e. Those are the spinal cord injuries.
There are different kinds of MS, as well as different stages of the disease. Currently, we know that the protective axon coating made from the white fatty myelin is destroyed in the patients who suffer from MS ( 2).As a result, they experience serious sensory or motor disruption. However, scientists are working on it and hopefully, we will be able to successfully treat it in the near future. This is a disease that we still don't know the cure for. The reason is simple: the white matter is responsible for the smooth and proper operation of the nervous system.It is interesting to focus on MS or Multiple sclerosis.
ConclusionThe gray matter which got its name for the dark, grayish color, contains neural cell bodies. As with the usual strokes, they harden and prevent nutrients and oxygen from reaching the brain regions. The reason is the fact that diseases that affect white matter also affect the blood vessels in it. On the other hand, the progressive MS leads to a neuron death caused by the axonal damage, which is an irreversible state ( 2).Moreover, we today know that the white matter disease leads to around one-fifth of strokes.
Besides, damage to the ventral gray horn prevents the normal functioning of the motor information receipt system. It is responsible for sending the descending nerve signals to the autonomic nerves to govern the motor activities.Damage of the gray matter, more precisely the dorsal gray horn may result in difficulties in interpreting the sensory information. It is especially important for passing the sensory information to the brain through the ascending nerve signals.The anterior part of this butterfly-like shape is known as the ventral gray horn. The posterior part of this structure is known as the dorsal gray horn. Namely, it forms a butterfly-shaped structure in its central part. The brain zones in which it prevails include the cerebrum, the cerebellum, and truncus encephali or the brain stem.It is also found in the spinal cord.
