Question

lets start with the motor signal you just tracked. this signal went from the central nervous system to the thumb. what direction would a sensory signal travel? a) from the peripheral nervous system to the thumb b) from the central nervous system to the thumb c) from the thumb to the central nervous system d) from the thumb to the peripheral nervous system

Explanation:

Sensory signals carry information from sensory receptors (like those in the thumb) to the central nervous system (brain and spinal cord) for processing. Motor signals go from the central nervous system to muscles (like in the thumb for movement). Option a is incorrect as it's not the typical path for sensory signals. Option b is the path of motor signals. Option d is an incorrect description of the sensory signal's direction as the final destination is the central nervous system, not just the peripheral nervous system (which is the pathway but not the end - point for processing in this context).

Answer:

C. From the thumb to the central nervous system
