Humans possess a complex nervous system that comprises numerous specialized cells called neurons and supporting glial cells, which communicate through electrical and chemical signals. The human brain consists of billions of interconnected neurons, forming an intricate network that facilitates thought, perception, emotion, and movement. A typical neuron has multiple dendrites that receive synaptic inputs from other neurons, a cell body or soma where the integration of information takes place, and a long extension called an axon that transmits signals to other neurons, muscles, or glands. Human brains are made up of various structures including the cerebrum, cerebellum, brainstem, and limbic system, each with distinct functions that contribute to overall cognitive, emotional, and physical well-being.
