Question

which is a function performed by the central nervous system (cns)? select all that apply.
□ processing information that is received from the stimuli receptors
□ receiving stimuli and making the body react to those stimuli
□ sending out information so that the body can react appropriately to stimuli
□ coordinating reflexes and reactions to stimuli
□ sensing stimuli and causing reactions in the body

Explanation:

1. Processing information from stimuli receptors: The CNS (brain and spinal cord) processes sensory information received from receptors (like eyes, skin). This is a key function.
2. Receiving stimuli and making body react: The peripheral nervous system (PNS) receives stimuli, while CNS processes and initiates response. So this is not a CNS - only function.
3. Sending out information for body reaction: After processing, CNS sends motor commands (via PNS) to effectors (muscles, glands) so body reacts appropriately. This is a CNS function.
4. Coordinating reflexes and reactions to stimuli: The spinal cord (part of CNS) coordinates reflexes, and the brain coordinates more complex reactions. This is a CNS function.
5. Sensing stimuli and causing reactions: Sensing stimuli is done by PNS receptors; CNS processes and initiates response, not sensing. So this is not a CNS function.

Answer:

• processing information that is received from the stimuli receptors
• sending out information so that the body can react appropriately to stimuli
• coordinating reflexes and reactions to stimuli
