The parasympathetic system has more control, as the sympathetic system includes hormonal effectors that work across the entire body.
An antagonist in the autonomic nervous system is a substance that blocks the action of neurotransmitters at specific receptors. This can result in the inhibition of certain physiological responses mediated by the autonomic nervous system, such as heart rate or smooth muscle contraction. Antagonists are often used in medicine to treat conditions where modulating autonomic functions is beneficial.
Both visceral activities and involuntary response are controlled by a specific part of the brain know as the Mendullu although this part of the brain sends signals to the Central Nervous System (CNS) which has overall control of the body's visceral activities.
Norepinephrine is mainly secreted by the adrenal medulla and also by specific neuron terminals in the sympathetic nervous system. It acts as both a hormone (when released into the bloodstream) and a neurotransmitter (when released at synapses).
Cells that are specialized for specific functions, such as nerve cells and muscle cells, would most prefer not to have cells undergoing division.
In prophase, the specific onion root cell that is undergoing cell division is the one that is preparing to divide and replicate its genetic material.
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.

parasympathetic
The autonomic ganglia of the parasympathetic system are called terminal ganglia or intramural ganglia. They are located near or within the target organs, allowing for more localized and specific control of parasympathetic functions.

Preganglionic fibers of the parasympathetic division of the autonomic nervous system synapse with postganglionic neurons in the ganglia located near or within their target organs. This allows for the transmission of nerve impulses from the central nervous system to the specific organs to regulate functions like digestion, salivation, and smooth muscle contraction.
Both visceral activities and involuntary response are controlled by a specific part of the brain know as the Mendullu although this part of the brain sends signals to the Central Nervous System (CNS) which has overall control of the body's visceral activities.
Impulses carried to the heart by fibers that secrete acetylcholine are typically from the parasympathetic nervous system. Acetylcholine acts on specific receptors in the heart to slow the heart rate. This helps regulate the heart's activity and maintain balance in the autonomic nervous system.
The prognosis for persons suffering autonomic dysfunction is variable and depends on specific dysfunction and on the severity of the dysfunction. Autonomic dysfunctions can present as acute and reversible syndromes.
Autonomic Reflexes are micro movements in response to specific stimuli that are not regulated by conscious effort. Its most effective use is in the Autonomic Digital Reflexapproach in which twitches of the fingers are decoded as meaningful reactions of the body's inner state.
sympathetic
The autonomic nervous system is controlled by the brainstem, hypothalamus, and spinal cord. The pituitary gland is controlled by the hypothalamus through the release of specific hormones that regulate pituitary function.
