Unopposed sympathetic activity is when the sympathetic nervous system is overly stimulated without a counterbalancing effect from the parasympathetic nervous system. It can lead to symptoms such as rapid heart rate, high blood pressure, sweating, and feelings of anxiety or agitation. This imbalance can occur in conditions like panic attacks or certain drug overdoses.
Activating the parasympathetic nervous system through activities like deep breathing, relaxation techniques, and meditation can decrease sympathetic activity, reducing anxiety and nervousness. Additionally, participating in activities like exercise, spending time in nature, and socializing can also help to lower sympathetic activity and promote a sense of calm.
Sympathetic stimulation can be increased by various factors, including physical stressors like exercise, emotional stress, and perceived threats. Hormonal responses, particularly the release of adrenaline (epinephrine) from the adrenal medulla, also enhance sympathetic activity. Additionally, certain medications and stimulants, such as caffeine, can elevate sympathetic stimulation by affecting neurotransmitter release and receptor activity.
Sympathetic postganglionic fibers end in effector organs such as smooth muscles, cardiac muscles, and glands. They innervate these structures to modulate their activity in response to stress or stimulation of the sympathetic nervous system.
Sympathetic inhibition refers to a decrease in the activity of the sympathetic nervous system, which is responsible for the fight-or-flight response. This can result in a decrease in heart rate, blood pressure, and overall stress levels in the body. Sympathetic inhibition is often associated with relaxation, rest, and recovery.
Sympathetic activity inhibits gastric secretion by causing vasoconstriction of blood vessels in the stomach lining. Parasympathetic activity stimulates gastric secretion by increasing blood flow and activating gastric glands, leading to increased production of stomach acid and digestive enzymes.
No, sympathetic activity typically causes vasoconstriction, not vasodilation.

The relationship between blood pressure and sympathetic activity is characterized by a regulatory mechanism where increased sympathetic activity leads to higher blood pressure. The sympathetic nervous system stimulates the heart to beat faster and stronger, constricts blood vessels, and increases the release of hormones like norepinephrine, all contributing to elevated blood pressure. Conversely, when blood pressure decreases, sympathetic activity is heightened to restore blood pressure to normal levels. Thus, there is a dynamic balance between sympathetic activity and blood pressure regulation in the body.

The pacemaker of the heart is known as the sinoatrial (SA) node. It sets the rate at which the heart will beat without any autonomic stimulation, that is, no sympathetic or parasympathetic activity. Increases in sympathetic activity will increase the heart rate while increases in parasympathetic activity decrease heart rate. The pacemaker of the heart is known as the sinoatrial (SA) node.

Autonomic tone
CNS modulation of the autonomic nervous system (ANS) does not rely entirely on efferent stimulation through the parasympathetic nervous system; it also involves sympathetic pathways. The CNS regulates both the sympathetic and parasympathetic branches, allowing for a balance between the two. Perceived sympathetic activity is not merely a product of the absence of parasympathetic influence; it represents a distinct activation of the sympathetic nervous system, which can occur independently of parasympathetic activity.

Innervated by both the sympathetic and parasympathetic nervous system. This allows for both branches of autonomic NS (sympathetic and parasympathetic) to precisely control an organ's activity.
