Grey matter is a type of tissue in your brain and spinal cord (central nervous system) that plays a crucial role in allowing you to function normally from day to day. It consists of high concentrations of neuronal bodies, axon terminals (endings) and dendrites.
The grey matter throughout the central nervous system allows enables individuals to control movement, memory, and emotions. Different areas of the brain are responsible for various functions, and grey matter plays a significant role in all aspects of human life.
The grey matter that surrounds the cerebrum, also given the name cerebral cortex, is involved in several functions such as being involved in personality, intelligence, motor function, planning, organization, language processing, and processing sensory information.
Learn how gray and white matter in the central nervous system differ in their location and function, as well as how various diseases affect both.
Grey matter, or brain matter in American English, is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.
Grey matter plays a significant role when it comes to how our mind and body function. It allows people to control their motor movements and it allows us to receive sensory signals from our environment. Grey matter also plays important cognitive and mental health roles.
Gray matter, also spelled grey matter (British spelling) and also called substantia grisea, is the part of the brain that is controlled by the true dendrites (the short branching fibers that carry messages and impulses to the cell body) and nerve cell bodies (which bring information to the neurons).
