The spinal cord.
"reflexes"
The division of the autonomic nervous system responsible for each of the reflexes is the ciliospinal reflex. Ciliospinal reflex responds mainly by the 2nd and 3rd order nerves to the muscle of the iris.
I'm not positive, but I think that reflexes are controlled by the sympathetic nervous system (SNS). The sympathetic nervous system is part of the autonomic nervous system (ANS), which is part of the peripheral nervous system (PNS). The SNS is responsible for fight-or-flight responses. For example, if you see a shark coming directly at you, you decide to try to either get away from it (flight) or fight it off (fight). Reflexes are mediated by reflex arcs, which are neural pathways. Some sensory neurons pass directly to the synapse of the spinal cord, rather than the brain. This allows reflexes to occur relatively quickly.
The autonomic nervous system does. It works at the level of the spinal cord.
There area few reflexes when coming to a newborn. The main reflex would be the central nervous system.

i believe it is the "Somatic" Nervous System. Since the Somatic is Voluntary and all. The Somatic is the part of the Nervous System that is responsible for consciousness movement and action. However, some systems in the Somatic are still involuntary, like reflexes. The Somatic Nervous System is part of the Peripheral Nervous System.
To confirm correct formation of their nervous system.
The central nervous system.
The nervous system including the central nervous system and the peripheral system are responsible for coordination and control.
The two integral parts of the autonomic nervous system are the sympathetic nervous system responsible for, "rest and digest" and the parasympathetic nervous system that is responsible for, "fight or flight".
Nervous system and Muscular system usually. For some, the Sensory system, a part of the Nervous system, also has to do with reflexes.
