Sympathetic tone refers to the level of activity in the sympathetic nervous system, which is responsible for the body's "fight or flight" response. It helps regulate various physiological processes such as heart rate, blood pressure, and breathing in response to stress or danger. Maintaining an appropriate sympathetic tone is crucial for the body to respond effectively to different situations and maintain balance in its functions.

Describe the meaning and importance of sympathetic tone and parasympathetic tone?
Both your sympathetic and parasympathetic neurons have a constant rate of firing under normal conditions. This is called their "tone", and it maintains the normal rate of your heartbeat, keeps your blood pressure within a normal range and such to maintain homeostasis. Of course, the sympathetic and parasympathetic firing rate changes greatly during fight-or-flight responses and such.

What causes arterioles to dilate in response to increased sympathetic tone?
Increased sympathetic tone leads to the release of norepinephrine, which binds to alpha-1 adrenergic receptors on arteriolar smooth muscle. This binding initiates a signaling cascade that ultimately results in the relaxation of the smooth muscle, causing the arterioles to dilate.

Is white rami exclusive to the sympathetic division of the ANS?
No, white rami are not exclusive to the sympathetic division of the autonomic nervous system (ANS). While they are primarily associated with the sympathetic division, specifically as pathways for preganglionic sympathetic fibers to enter the sympathetic ganglia, similar structures exist in the parasympathetic division. However, the term "white rami" typically refers to the myelinated preganglionic fibers of the sympathetic system.
