Final answer:
Interneurons conduct action potentials between neurons within the CNS, acting as a link between sensory neurons and motor neurons.
Step-by-step explanation:
The cells that conduct action potentials from one neuron to another within the Central Nervous System (CNS) are called interneurons. Interneurons serve as the link between sensory neurons, which carry nerve impulses from tissues and organs to the CNS, and motor neurons, which carry impulses from the CNS to the muscles and glands. Interneurons facilitate communication within the CNS by transmitting impulses between sensory and motor neurons, thereby playing a crucial role in the coordination of sensory input and motor output.
