Sep 18, 2023 · White matter in the brain consists of myelinated axons, which are nerve fibers covered by a fatty insulating layer called myelin. This structure allows for rapid transmission of neural signals between brain regions. White matter essentially acts as the brain's communication network, connecting different parts of gray matter and facilitating coordinated brain function.
Main Parts of the Brain and Their Functions. At a high level, the brain can be divided into the cerebrum, brainstem and cerebellum. Cerebrum. The cerebrum (front of brain) comprises gray matter (the cerebral cortex) and white matter at its center. The largest part of the brain, the cerebrum initiates and coordinates movement and regulates ...

Feb 20, 2024 · The brain and spinal cord consist of gray matter (substantia grisea) and white matter (substantia alba). White Matter: Consists mainly of axons and myelin sheaths that send signals between different brain regions and between the brain and spinal cord. Gray Matter: Consists of neuronal cell bodies, dendrites, and axon terminals. Gray matter ...
Nov 9, 2023 · The cortex contains neurons (grey matter) interconnected to other brain areas by axons (white matter). The cortex has a folded appearance. A fold is called a gyrus, and the valley between is a sulcus. The cerebral cortex is primarily constructed of grey matter (neural tissue made up of neurons), with between 14 and 16 billion neurons found here.
Jan 24, 2024 · Gray matter is made up of neuronal cell bodies, while white matter primarily consists of myelinated axons. In the brain, white matter is found closer to the center of the brain, whereas the outer cortex is mainly grey matter. The reverse is true in the spinal cord, which has a grey matter-lined interior with white matter on the outside.

Oct 30, 2023 · Cortex cerebri. Synonyms: Brain cortex, Cortical grey matter. The cerebral cortex (cortex of the brain) is the outer grey matter layer that completely covers the surface of the two cerebral hemispheres. It is about 2 to 4 mm thick and contains an aggregation of nerve cell bodies. This layer is thrown into complex folds, with elevations called ...
