Spinal Cord

The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It transmits nerve signals from the brain to the rest of the body.

Neural Impulse

An electrical signal that travels along neurons, facilitating communication within the nervous system.

Action Potential

Action potential is the rapid change in electrical charge across a neuron's membrane, allowing for the transmission of nerve signals.

Interneurons

Neurons that transmit impulses between other neurons, especially as part of a reflex arc in the spinal cord or between sensory and motor neurons.
