Gray Matter and White Matter – Gray matter and white matter are two types of components found in the nervous system. Gray matter comprises a high number of neuron cell bodies, which seem to be gray in preserved tissue but pink or light brown in live tissue. White matter, on the other hand, is mostly made up of axons and is named after the color of the fatty insulation known as myelin that covers many axons. All of the PNS nerves, as well as most of the inside of the brain and spinal cord, are white matter. Gray matter is seen in clusters of neurons and cortical layers that line the surfaces of the brain and spinal cord.
Cerebrum – Gray matter and white matter make up the cerebrum or the front of the brain. The cerebrum, the biggest region of the brain, controls temperature and starts and directs movement. Speech, judgment, thinking and reasoning, problem-solving, emotions, and learning are all facilitated by other parts of the cerebrum. Vision, hearing, touch, and other senses are also among the other functions.
Cerebellum – The cerebellum (also referred to as the “little brain”) is a fist-sized region of the brain situated behind the head, above the brainstem, and below the temporal and occipital lobes. It has two hemispheres. The inner area communicates with the cerebral cortex, while the outer area contains neurons. Its job is to keep posture, balance, and equilibrium by coordinating voluntary muscle movements.
Spinal cord – The spinal cord is a long band of tissue that resembles a tube. It has a cylindrical shape to it. It is the link between your brain and your lower back. Nerve impulses go from your brain to your body via your spinal cord. These nerve impulses aid in the perception of feelings and the movement of the body. Because it is so sensitive, any injury to your spinal cord can have an impact on your mobility and function.
