the parasympathetic division
the central nervous system
the endocrine system
the sympathetic division

somatic nerves.
autonomic nerves.
spinal cord and somatic nerves.
brain and spinal cord.

Explanation:

1. For the first question: The sympathetic division of the autonomic nervous system activates the fight-or-flight response, mobilizing bodily resources during emergencies. The parasympathetic division regulates rest-and-digest functions, the central nervous system is the overall control center (not the fight-or-flight branch), and the endocrine system works with but is not the nervous system branch in question.
2. For the second question: The central nervous system (CNS) is defined as consisting of the brain and spinal cord. Somatic and autonomic nerves are part of the peripheral nervous system, not the CNS.

Answer:

1. The sympathetic division
2. brain and spinal cord.
