Which of the following neurons are responsible for relaying information within the central nervous system?

Interneurons play a crucial role in the central nervous system (CNS) by facilitating communication between other neurons. They are primarily responsible for relaying signals between sensory (afferent) neurons and motor (efferent) neurons, as well as connecting with other interneurons to form complex networks. This allows interneurons to process and integrate information, enabling reflexes and higher cognitive functions.

Efferent neurons transmit signals from the CNS to muscles or glands, leading to an action but do not relay information within the CNS itself. Afferent neurons, on the other hand, carry sensory information from the body to the CNS but are not involved in the internal communication within the CNS. Motor neurons specifically refer to those neurons that directly control muscle movements but do not relay information among other neurons in the central nervous system.

Thus, interneurons are the correct answer as they are the dedicated cells within the CNS that facilitate communication and processing of information between different types of neurons.
