However, the human brain contains two main types of cells:
* Neurons: These are the fundamental building blocks of the nervous system. They receive, process, and transmit information throughout the brain and body. There are many different types of neurons, each with specialized functions.
* Glial cells: These cells provide support and protection for neurons. They perform a variety of functions, including:
* Astrocytes: Provide structural support, regulate blood flow, and help maintain the chemical environment around neurons.
* Oligodendrocytes: Form myelin sheaths around axons, which help speed up signal transmission.
* Microglia: Act as the immune cells of the brain, removing debris and pathogens.
There are many other specialized cell types in the brain, but these are the most common.
