Understand the Problem
The question is asking to match specific terms related to the nervous system with their correct definitions. Efferent and Afferent are types of neural pathways, while Nerve and Tract refer to bundles of axons either inside or outside the CNS.
Answer
Efferent: Exiting information out of the CNS, Nerve: A bundle of axons outside the brain and spinal cord, Tract: A bundle of axons inside the brain and spinal cord, Afferent: Arriving information to the CNS.
Efferent: Exiting information out of the CNS, Nerve: A bundle of axons outside the brain and spinal cord, Tract: A bundle of axons inside the brain and spinal cord, Afferent: Arriving information to the CNS.
Answer for screen readers
Efferent: Exiting information out of the CNS, Nerve: A bundle of axons outside the brain and spinal cord, Tract: A bundle of axons inside the brain and spinal cord, Afferent: Arriving information to the CNS.
More Information
Neurons are specialized cells that transmit information throughout the body. Afferent neurons relay sensory signals to the CNS, while efferent neurons carry motor commands away. Peripheral nerves consist of bundles of axons in the PNS, contrasting with tracts, which are axon bundles within the CNS.
Tips
Confusing the pathways of afferent and efferent neurons is common. Remember, afferent neurons convey information to the CNS, similar to incoming mail, while efferent neurons direct instructions from the CNS, akin to outgoing mail.
