There are three main types of neurons: sensory neurons, motor neurons, and interneurons. Sensory neurons carry signals from sensory organs like the skin to the brain and spinal cord. Motor neurons transmit signals from the brain and spinal cord to muscles, directing movement. Interneurons relay messages between other neurons within the brain and spinal cord.
