what are neurons

Neurons, also known as nerve cells, are the fundamental units of the brain and nervous system. They are responsible for receiving sensory input from the external world, sending motor commands to our muscles, and transforming and relaying electrical signals. Neurons communicate with each other using electrical and chemical signals, and they play a crucial role in everything we think, feel, and do. A neuron has three main parts: dendrites, an axon, and a cell body or soma. Dendrites receive signals, the cell body processes the signals, and the axon transmits the signals to other neurons. There are three main types of neurons: sensory neurons, motor neurons, and interneurons, each with its own function in the nervous system
