A neuron is a nerve cell. The brain is made up of approximately 100 billion neurons. Neurons are similar to other cells in the body in some ways such as: Neurons are surrounded by a membrane. Neurons have a nucleus that contains genes. Neurons contain cytoplasm, mitochondria and other organelles.
Answers: Don't confuse axons with neurons. There are approximately 100,000,000,000 neurons in the human brain. Most of them are support cells and have nutritive, immunologic and protective functions. The number of axons per cell vary, mostly in the types of cells. For example Purkinje cells have many axons and therefore many more connections.
