Verified step by step guidance

Understand the roles of efferent and afferent neurons: Afferent neurons carry sensory information from the body to the central nervous system (CNS), while efferent neurons transmit motor commands from the CNS to the body.

Recognize the anatomical structures involved: The spinal cord is connected to peripheral nerves through structures called roots. These roots are divided into dorsal roots (sensory/afferent) and ventral roots (motor/efferent).

Clarify the function of the dorsal and ventral roots: The dorsal roots are responsible for transmitting sensory information into the spinal cord, while the ventral roots carry motor signals out of the spinal cord.

Eliminate incorrect options: The cerebral peduncles are part of the brainstem and are involved in motor pathways, not spinal cord entry. The meninges are protective coverings of the CNS and do not serve as pathways for neurons. The corpus callosum connects the two hemispheres of the brain and is unrelated to spinal cord entry.

Conclude that efferent and afferent neurons pass through the dorsal and ventral roots to enter and exit the spinal cord, respectively.
