Which statement describes motor information in the nervous system?

• A. Converges and is Efferent
• B. Diverges and is Afferent
• C. Diverges and is Efferent
• D. Converges and is Afferent

Answer: (A)

Motor information travels away from the central nervous system to the muscles, so it is efferent. In motor pathways, many upstream signals are integrated as they converge onto motor neurons or motor pools to produce coordinated muscle activation, allowing precise control of movement. Describing motor information as afferent would be incorrect because afferent refers to sensory signals entering the CNS. While divergence exists in some circuits (one command influencing multiple muscles), the defining feature here is that motor output is efferent and typically involves convergence of inputs to drive the appropriate motor response.
