a specialized cell that transmits electrical signals in the nervous system
What is a "nerve cell "?
A nerve cell, or neuron, is a fundamental building block of the nervous system. It is a highly specialized cell responsible for transmitting electrical signals and information throughout the body. Nerve cells consist of a cell body, which contains the nucleus and other organelles, and long, slender extensions called dendrites and axons. Dendrites receive signals from other neurons, while axons transmit signals to other cells. Nerve cells play a crucial role in processes such as sensation, movement, and cognition, allowing for the complex functioning of the nervous system.
