Praxis 5857 Practice Test Practice Question
Which of the following structures transmits information from the muscles to the brain?
Correct Answer: A
Rationale: Afferent neurons are responsible for transmitting sensory information from muscles and other body parts to the brain, enabling the perception of movement and position. Efferent neurons, on the other hand, carry signals from the brain to muscles, facilitating movement rather than relaying information. Motor neurons specifically refer to a subset of efferent neurons that directly control muscle contractions. Interneurons function as connectors within the central nervous system, processing information but not directly transmitting sensory data from muscles to the brain. Thus, only afferent neurons fulfill the role of conveying muscle information to the brain.
