Final answer:
The nerves that come out of the spinal cord and go to organs are controlled automatically by the autonomic nervous system. Reflexes, on the other hand, are controlled by the spinal cord.
Step-by-step explanation:
The nerves that come out of the spinal cord and go to organs are controlled automatically by the autonomic nervous system. This system is responsible for controlling involuntary functions of the body, such as heart rate, blood flow, and digestion. It sends messages between parts of the nervous system and other organ systems through neurotransmitters.
Reflexes, on the other hand, are controlled by the spinal cord. They are quick, unconscious movements that happen without any input from the brain. For example, automatically removing a hand from a hot object is a reflex controlled by local synaptic connections.
