White and gray matter

Dissection of human brain, lateral view, showing the gray matter (darker, outermost areas), and the white matter (innermost, distinctly white areas).Name and classificationSynonyms

The white matter (or white matter) is a part of the central nervous system composed of myelinated (myelin-coated) nerve fibers. Nerve fibers contain mostly many axons (an axon is the part of the neuron responsible for transmitting information to another nerve cell). The so-called gray matter, on the other hand, is composed of the somas and neuronal bodies, which do not have myelin, and is more related to information processing. White matter, long thought to be a passive tissue, actively affects how the brain learns and functions. While gray matter is primarily associated with processing and cognition, white matter modulates the distribution of action potentials, acting as a relay and coordinating communication between different regions of the brain.[1] The white matter is also associated with the brain’s ability to process information.

How is the gray and white matter formed?

The tissue called “gray matter” present in the brain and spinal cord is also known as gray matter and is composed of cell bodies. The “white matter” or substantia alba is composed of nerve fibers.

What is white matter?

The white matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). … It contains the cell bodies of neurons, which give color to the gray matter.

What is in the white matter?

The white matter is made up of millions of communication pathways, each composed of a long, independent cable, the axon, covered by a white, fatty substance: myelin.

What is a white matter lesion?

According to existing clinical evidence, cerebral white matter lesions are a predictor of vascular death in elderly patients, increase the risk of recurrence in patients with a history of ischemic stroke, and confer an increased risk of intracranial hemorrhage in patients with a history of ischemic stroke, and …

What is the gray matter?

Gray matter refers to amyelinic neurons and other cells of the central nervous system: it is present in the cerebrum, brainstem and cerebellum, and throughout the spinal cord. … However, gray matter density appears to increase as a person reaches early adulthood.

What is gray matter and what is its function?

Its function is to transport the stimulus from the receptor to the dorsal horn of the medulla. … The gray matter of the spinal cord consists of a collection of multipolar neuronal somas, neuroglia and blood vessels.

Gray and white matter function

Abscesses form when bacteria, fungi, or other germs enter the body (usually through an open wound, such as a cut) and cause an infection. When this happens, the body’s immune system is activated and sends out white blood cells to fight the infection. These white blood cells, along with other debris, which collects in the wound, form pus. When pus accumulates, it may not drain and the area becomes painful.

Abscesses are usually swollen, red, warm to the touch and may ooze fluid. They may develop on the outermost layer of the skin, under the skin, in a tooth or even deep within the body. On the surface of the skin, an abscess may look like an unhealed wound or pimple; under the skin, it may appear as a swollen lump. The area may be painful and tender.

To help the abscess open and drain well, try applying warm compresses over it. You can make a compress by soaking a towel in warm (not hot) water and placing it over the abscess for several minutes. Do this several times a day. Always wash your hands before and after touching the abscess.

What is the function of the gray and white matter?

Information processing takes place in the gray matter, while the white matter enables communication between different areas of the gray matter, and between the gray matter and other parts of the body. The gray matter has no myelin sheaths, whereas the white matter is myelinated.

What are periventricular lesions?

Periventricular leukomalacia (PVL) is a type of brain injury that affects premature infants. The condition involves the death of small areas of brain tissue around the fluid-filled areas called ventricles. The damage creates “holes” in the brain.

How is the white matter status assessed?

Magnetic resonance imaging detects alterations in the white matter of the cerebellum, thalamus, frontal and parietal cortexes and hippocampus.

The deeper, larger or dirtier a wound is, the more care it needs. That’s why teams of doctors and nurses specially trained and experienced in wound care work together to monitor and treat serious wounds.

If the wound is clean, the doctor will close it with stitches, bringing its edges together in two distinct layers. The physician will use absorbable (dissolvable) stitches to bind the deeper layer of tissue under the skin. He or she will then use staples, tape or stitches to bind the more superficial layer of skin together.

Sometimes doctors use absorbable stitches or absorbable tape to bind both the top and bottom layers of skin together. Otherwise, the doctor will remove the superficial stitches or staples after 7 to 10 days.

However, doctors do not always close wounds immediately. If there is a possibility that the wound is contaminated, they will leave it open so that it can be cleaned thoroughly (for example, if it is an animal bite). If a contaminated wound were to be closed, bacteria could be retained inside, which could lead to infection. When doctors are sure that no bacteria or other contaminants remain inside the wound, they will close it with stitches, tape or staples.
