What happens if you have a tumor in your cerebellum?

What happens if you have a tumor in your cerebellum?

If the tumor is in the cerebellum (the lower, back part of the brain that controls coordination), a person might have trouble walking; trouble with precise movements of hands, arms, feet, and legs; problems swallowing or synchronizing eye movements; and changes in speech rhythm.

What do GREY and white matter in brain represent?

The grey matter represents the high concentration of cell bodies of the neuron. The inner region of cerebrum is composed of white matter which is also called cerebral medulla. The white matter represents the high concentration of axons which gives it lighter appearance.

What happens if GREY matter is damaged?

Since the neuronal cells of the grey matter are constantly working, they require a high supply of oxygen to function efficiently. Therefore when the grey matter does not have access to oxygen, the cells will begin to die, leading to possible irreversible brain damage and loss of function.

What kind of tumors grow in the cerebellum?

Medulloblastoma is a type of brain cancer that starts in the part of the brain called the cerebellum. Medulloblastoma is the most common type of cancerous brain tumor in children.

What are the main clinical signs of a cerebellar tumor?

Symptoms

• New onset or change in pattern of headaches.
• Headaches that gradually become more frequent and more severe.
• Unexplained nausea or vomiting.
• Vision problems, such as blurred vision, double vision or loss of peripheral vision.
• Gradual loss of sensation or movement in an arm or a leg.
• Difficulty with balance.

What does it mean to have white matter on the brain?

White matter disease is the wearing away of tissue in the largest and deepest part of your brain that has a number of causes, including aging. This tissue contains millions of nerve fibers, or axons, that connect other parts of the brain and spinal cord and signal your nerves to talk to one another.

What does white matter do in the brain?

White matter is tissue in the brain composed of nerve fibers. The fibers (called axons) connect nerve cells and are covered by myelin (a type of fat). The myelin is what gives white matter its white color. Myelin speeds up the signals between the cells, enabling the brain cells to quickly send and receive messages.

What is the white matter of the cerebellum called?

Answer and Explanation: The white matter in the cerebellum is also called the ‘”arbor vitae”‘, or tree of life, because it has the branch-like appearance of a tree. The arbor vitae contains axons, which are projections of nerve cells that carry nerve impulses to different parts of the brain and spinal cord.

Why are grey matter and white matter contained in human nervous system named so?

The axons are wrapped in myelin, which insulates the axons and allows to send them signals quickly. The type of fat in myelin looks white, and thus white matter. Gray matter is mostly what you call glial cells. These cells are not surrounded by white myelin and thus take the grayish color.

What is the difference between Gray and white matter in the brain?

A lot of confusion revolves around the distinction between gray and white matter in the brain, but the difference is actually a pretty simple one. Gray matter, named for its pinkish-gray color, is home to neural cell bodies, axon terminals, and dendrites, as well as all nerve synapses.

Where is the white matter of the cerebellum located?

The white matter of the cerebellum is also present in its deep part. In the cerebellum, the white matter contains four cerebellar nuclei: dentate nucleus, globose nucleus, emboliform nucleus, and fastigial nucleus. In the spinal cord, the white matter is present on the superficial side and the grey matter is in the center of white matter.

What is the role of gray matter disease in the pathophysiology?

Gray matter disease might help explain the observed dissociation between markers of inflammatory demyelination (relapses, white matter gadolinium enhancement, white matter lesion burden) and disease progression. It’s likely that gray matter damage is related to white matter damage.

What are the white matter regions of the central nervous system?

The white matter regions of the central nervous system (CNS) contrast with the gray matter regions. The white matter refers to those parts of the brain and spinal cord that are responsible for communication between the various gray matter regions and between the gray matter and the rest of the body.
