Detailed explanation-1: -Unlike the structure of the spinal cord, the grey matter in the brain is present in the outermost layer. The grey matter surrounding the cerebrum is known as the cortex of the brain.
Detailed explanation-2: -Your cerebral cortex, also called gray matter, is your brain’s outermost layer of nerve cell tissue. It has a wrinkled appearance from its many folds and grooves.
Detailed explanation-3: -The medulla oblongata consists of both cells and fibres, which are arranged similarly to those in the spinal cord, thecells or grey matter being on the inside and the fibres of white matter on the outside. It lies at the base of the skull just in front of the foramen magnum and links the pons and spinal cord.
Detailed explanation-4: -Grey matter is mostly neuron cell bodies and non-neuron brain cells called glial cells. These glial cells provide nutrients and energy to neurons. 2. Grey matter helps transport glucose into the brain, clean the brain of excess chemicals, and may even affect the intensity of the neurons’ communications.
