Which autonomic nervous system fibers release norepinephrine?
The autonomic nervous system fibers that release norepinephrine are primarily the postganglionic sympathetic fibers. These fibers originate in the sympathetic ganglia and project to various target organs, where they release norepinephrine to mediate the "fight or flight" response. In contrast, the preganglionic sympathetic fibers release acetylcholine.
Which division of the autonomic nervous system is involved in secreting norepinephrine via adrenergic nerve fibers?
Sympathetic nervous system .
Which division of the autonomic nervous system is characterized by short preganglionic and long postganglionic fibers?
The parasympathetic nervous system has long preganglionic and short postganglionic fibers
Sympathetic and parasympathetic nervous system's are subdivisions of what nervous system?
The sympathetic and parasympathetic nervous systems are subdivisions of the autonomic nervous system.
What fibers are the sweat glands innervated by?

What are the autonomic nervous system?
parasympathetic and sympathetic nervous systems
What branch of spinal nerve only contain autonomic fibers?
The branch of the spinal nerve that contains only autonomic fibers is the rami communicantes. These are divided into the white rami communicantes, which carry preganglionic sympathetic fibers to the sympathetic ganglia, and the gray rami communicantes, which carry postganglionic sympathetic fibers back to the spinal nerve. These branches are essential for the autonomic nervous system's regulation of involuntary functions.
What is between the sympathetic and the parasympathetic nervous system?
The parasympathetic and sympathetic divisions of the autonomic nervous system or antagonistic. They have opposing effects.
